Features and Benefits

Overview

The CCM console management appliance provides non-blocked access and control for devices such
as serial-managed Linux (or other UNIX) servers, routers, power management devices and firewalls.
This includes Avocent SPC power control devices that provide advanced power management.

• The CCM850 appliance has 8 serial ports. A single 10/100 Mbps Ethernet port provides net­work connectivity on each appliance. Two CCM850 appliances may be mounted in 1U of ver­tical space in a standard 19 inch rack.

• The CCM1650 appliance has 16 serial ports. A single 10/100 Mbps Ethernet port provides
network connectivity on each appliance. Two CCM1650 appliances may be mounted in 1U of
vertical space in a standard 19 inch rack.

• The CCM4850 appliance has 48 serial ports. A single 10/100/1000 Mbps Ethernet port
provides network connectivity on each CCM appliance. One CCM4850 appliance may be
mounted in 1U of vertical space in a standard 19 inch rack.

Each appliance has a console port that uses a Command Line Interface (CLI) for configuration,
management and optionally, connection to other ports.

1

Serial device access options

You may choose from among several client application options to access the CCM appliance and
its attached serial devices:

• The AVWorks
client and a Secure Shell (SSH) client

• Third party Telnet clients

• Third party SSH clients

Access to attached serial devices is also possible through the appliance serial CLI, plus PPP (Point
to Point Protocol) and other types of dial-in connections to a modem on the console port.

When session sharing is enabled, the CCM appliance supports multiple concurrent sessions.
Configured user access levels may be used as preemption criteria for serial port access.

®

cross-platform management application that offers a built-in enhanced Telnet

2 CCM Installer/User Guide

User authentication and data security

The CCM user database supports up to 64 user accounts, which include usernames, passwords and/
or keys, plus specifications of access rights/levels to CCM appliance ports and commands. User
definitions may be changed at any time. You may choose to have user access authenticated locally
at the CCM user database and/or at one or more RADIUS (Remote Access Dial-In User Service)
servers. Data security may be enhanced using industry-standard SSH encryption.

Extensive command set

The CCM appliance offers a wide range of commands that allow administrators to easily configure,
control and display information about the CCM appliance operating environment, including its
ports, user accounts and active sessions. The serial CLI is always available on the unit’s console
port, and may be easily accessed during a session with an attached serial device.

The user interface also offers descriptive error message data and built-in command help
information. On-board Trivial File Transfer Protocol (TFTP) support allows administrators to
upload new functionality to CCM appliances in the field.

Port history

Each CCM port has a buffer that holds the most recent 64K bytes of online and offline serial data.
A separate history command mode lets you navigate within a port’s current history file and conduct
tailored searches.

You may also configure the appliance to write serial port data to a file on an NFS server, thus
preventing data loss due to overflow of the history buffer.

Safety Precautions

To avoid potential device problems, if the building has 3-phase AC power, ensure that a computer
and its monitor (if used) are on the same phase. For best results, they should be on the same circuit.

To avoid potentially fatal shock hazard and possible damage to equipment, please observe the
following precautions:

• Do not use a 2-wire extension cord in any product configuration containing this appliance.

• Test AC outlets at the computer and monitor (if used) for proper polarity and grounding.

• Use only with grounded outlets at both the computer and monitor. When using a backup Unin­terruptible Power Supply (UPS), power the computer, the monitor and the CCM appliance off
the supply.

NOTE: The AC inlet is the main disconnect.

Rack mount safety considerations

• Elevated Ambient Temperature: If installed in a closed rack assembly, the operation tempera­ture of the rack environment may be greater than room ambient. Use care not to exceed the
rated maximum ambient temperature of the unit.

• Reduced Airflow: Installation of the equipment in a rack should be such that the amount of air­flow required for safe operation of the equipment is not compromised.

• Mechanical Loading: Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.

• Circuit Overloading: Consideration should be given to the connection of the equipment to the
supply circuit and the effect that overloading of circuits might have on overcurrent protection
and supply wiring. Consider equipment nameplate ratings for maximum current.

• Reliable Earthing: Reliable earthing of rack mounted equipment should be maintained. Pay
particular attention to supply connections other than direct connections to the branch circuit
(for example, use of power strips).

Using AVWorks Software

The AVWorks cross-platform management application may be used to manage CCM appliances
and access attached devices. Using AVWorks software, you may perform most of the operations
that are described in this manual. This manual describes how to manage a CCM appliance by
entering commands using the CLI. The AVWorks Installer/User Guide describes how to manage a
CCM appliance using the graphic interface.

Installing the CCM Appliance

WARNING: This unit is not user serviceable. To avoid electrical shock, do not attempt to open the unit or operate

with the cover off. Do not attempt to make any repairs. See Appendix F on page 113 for information.

WARNING: The power outlet should be near the equipment and easily accessible.

To install the CCM appliance hardware:

1. Place the unit where you can connect cables between the serial devices and the CCM serial
ports, and where you can connect a LAN interface cable between the Ethernet hub or switch
and the CCM LAN connector.

2. Connect devices to the CCM serial ports; see Device Cabling on page 95 for cable information.
Connect each serial device to its appropriate power source, following the device’s documentation.

8 CCM Installer/User Guide

3. Attach a LAN interface cable to the LAN connector on the CCM appliance. A CAT 5 cable is
required for 100BaseT operation. For CCM4850 appliances, a CAT 6 cable is required for
1000BaseT operation.

4. Insert the power cord into the back of the CCM appliance. Insert the other end of the power
cord into a grounded electrical receptor.

5. Check that the POWER LED on the front of the unit is illuminated. If not, check the power
cable to ensure that it is inserted snugly into the back of the unit. The ONLINE LED will illu­minate within two to three minutes to indicate that the self-test is complete. If the ONLINE
LED blinks, contact Technical Support for assistance.

6. For CCM850/1650 appliances, check that the LINK LED is illuminated.

For CCM4850 appliances, check that the LAN port LEDs indicate that a 10, 100 or 1000 Mbps
link exists.

If there is no link, check the Ethernet cable to ensure that both ends are correctly inserted into
their jacks.

7. Once the POWER, ONLINE and appropriate LEDs are illuminated, proceed with the configu­ration process (if you will be using BootP, remove power from the appliance).

Configuring the CCM Appliance

To configure the CCM appliance, you must specify a unique IP address, plus other network address
information. This information will be stored in the CCM configuration database. During initial
login, you will specify a password for the Admin user.

Configuring the network address settings

You may configure the CCM appliance network address settings using AVWorks software, BootP
or the serial CLI on the console port.

To configure the network address settings using AVWorks software:

Using the AVWorks New Appliance Wizard is the easiest method to configure the CCM appliance
network address settings. See the AVWorks Installer/User Guide for instructions. After the
network address settings are configured, see Initial CCM appliance login on page 10.

To configure the network address settings using BootP:

1. Ensure that there is a BootP server on your network that is configured to correctly respond to a
BootP request from the CCM appliance. BootP servers require the Ethernet MAC address of
network devices. The Ethernet MAC address is printed on a label affixed to the appliance. See your
BootP server’s system administrator guide for information about configuring the BootP server.

2. After you have configured your network’s BootP server with the CCM appliance Ethernet
MAC address, IP address, subnet mask and gateway, restore power to the CCM appliance and
wait for the ONLINE LED to illuminate. Once this occurs, the CCM appliance has completed
the BootP protocol, obtained its network address information and stored these in FLASH.

Chapter 2: Installation and Configuration 9

3. You may verify that the BootP process was successful with a ping command, which tests net­work connectivity. The ping command is entered as:

ping <ip_address>

For example, the following command tests the network connectivity of a CCM appliance with
the IP address 192.168.0.5.

ping 192.168.0.5

4. If the CCM appliance completes the BootP successfully, you will see a display similar to
the following.

Pinging 192.168.0.5 with 32 bytes of data:
Reply from 192.168.0.5: bytes=32 time<10ms TTL=128
Reply from 192.168.0.5: bytes=32 time<10ms TTL=128
Reply from 192.168.0.5: bytes=32 time<10ms TTL=128
Reply from 192.168.0.5: bytes=32 time<10ms TTL=128

If the CCM appliance did not successfully obtain its IP address with the BootP protocol, you
will see a display similar to the following.

Pinging 192.168.0.5 with 32 bytes of data
Request timed out.
Request timed out.
Request timed out.
Request timed out.

In this case, check the address information provided to the BootP server to confirm it is correct.
Verify that the Ethernet LAN adaptor cable is correctly installed on the CCM appliance and the
Ethernet hub.

After the network address settings are configured successfully, launch a Telnet session to the
assigned IP address. Then, see Initial CCM appliance login on page 10.

To configure the CCM appliance using the serial CLI:

1. Attach a compatible device to the console port. The compatible device types are: ASCII,
VT52, VT100, VT102, VT220 and VT320.

For cable and adaptor information, see Device Cabling on page 95. You may use any terminal
emulation program that is available on your system.

2. Configure your terminal or terminal emulation program as follows.

Baud rate 9600
Bits per character 8
Stop bits 1
Flow control None

3. Press the

Return or Enter key until a prompt appears, requesting your username. If you do not

receive a prompt after pressing the key five times, check your cable and serial settings to be
sure that they are correct.

4. Proceed to Initial CCM appliance login on page 10.

You may reboot or reinitialize the CCM appliance by pressing a recessed button on the appliance
front panel or by issuing a command.

Rebooting

During a reboot, any active Telnet sessions, including your own, are terminated. Any configuration
changes that require a reboot will become effective when the reboot completes.

To reboot the appliance in hardware:

1. Locate the recessed RESET button on the front of the CCM appliance. An opened paper clip
may be used to depress the button.

2. Insert the opened paper clip in the recess, then depress the button.

To reboot the appliance with a command:

Issue a Server Reboot command.

Reinitializing

Reinitializing the CCM appliance removes configured information. This may be useful when
reinstalling the unit at another location in your network.You may erase the configuration database,
which contains all nonvolatile data except the IP address, subnet mask and gateway. You may also
erase both the configuration database and the network address information.

To reinitialize the CCM appliance in hardware:

1. Locate the recessed INIT button on the front of the CCM appliance. An opened paper clip may
be used to depress the button.

2. Insert the end of the opened paper clip in the recess, then depress and hold the button. The
ONLINE LED will blink, indicating an initialization has been requested. You have approxi­mately seven seconds to release the button before any action is taken.

After seven seconds, the ONLINE LED will blink more rapidly to confirm that the CCM
configuration database has been erased. Continuing to hold the INIT button for a few more seconds
will erase the IP address as well. The ONLINE LED will blink faster to confirm the deletion.

If any portion of FLASH is erased, the CCM appliance reboots when the INIT button is released.

Chapter 2: Installation and Configuration 11

To reinitialize the CCM appliance with a command:

1. Issue a Server Init command with the Config parameter if you wish to erase the configura­tion database but retain the network address information.

-or­Use the All parameter if you wish to erase the configuration database and the network
address information.

2. You are prompted to confirm or cancel the operation.

The appliance reboots after initializing the database and copying it to the configuration FLASH.

Overview

The CCM console management appliance and its ports are easily configured and managed to meet
your requirements for device connection, user authentication, access control, power status
monitoring, port history information display and Simple Network Management Protocol (SNMP)
compliance for use with third party network management products.

Configuring Global Settings

Generally, the CCM appliance-level commands affect console port operations, configure/initiate
physical operations and enable/disable features.

13

Console port settings

The Server CLI command includes parameters that configure the console port:

• The terminal type to be used

• Enabling/disabling connections to devices from the console port - see Connecting to devices
from the console port on page 18

• The modem initialization character - see Configuring and using dial-in connections on page 19

This command also covers the following:

• The CLI access character that will suspend a device session and place you in CLI command
mode (this value may be overridden at the port level) - see CLI Mode on page 26

• Local port history file processing options during connection and when a session ends - see
Managing Port History on page 33.

• The session time-out value, which indicates the period of inactivity that must occur before a
session is ended (this value may be overridden at the port level) - see Session time-out on
page 27

Network settings, updating firmware and rebooting/reinitializing the appliance

To change the CCM appliance IP, gateway or subnet addresses, use the Server Set command
(page 71).

14 CCM Installer/User Guide

To update the boot or application firmware on the appliance, use the Server FLASH command
(page 67).

The appliance may be rebooted or reinitialized by pressing a button on the appliance or by issuing a
command; see Rebooting and Reinitializing the CCM Appliance on page 10.

Updating the Appliance Clock

The CCM appliance supports the NTP protocol. When NTP is enabled, the real time clock on the
CCM appliance will be updated immediately after NTP is enabled, each time the appliance reboots
and optionally, at specified intervals.

You may specify one or two NTP servers to provide the time. An NTP server may be external or an
internal server that you supply. The primary server will be queried for the time first. If it does not
respond with a valid time, the secondary server will be queried.

To enable or disable NTP:

To enable NTP, issue an NTP command with the Enable parameter.

NTP ENABLE [IP=<prim_add>[,<sec_addr>]] [UPDATE=<hours>]

If this is the first time NTP is being enabled, you must specify at least one NTP server address.

If you want the time to be updated periodically, specify an update interval of up to 99 hours. If you
specify a zero interval value (which is the default), the time will be updated only when the CCM
appliance reboots.

When you enable NTP, you are prompted to confirm or cancel the operation.

To disable NTP, issue an NTP command with the Disable parameter.

NTP DISABLE

Updating the Appliance Clock on page 14

Configuring Serial Port Settings

You may configure a CCM port to support one of two types of target devices (TDs): SPC or console.

For more information about SPC power control devices, see the SPC Installer/User Guide.

A console TD may be a serial-managed Linux (or other Unix) server, router, firewall or other
supported serial device.

By default, CCM ports are configured with the settings listed in Table 3.2.

Table 3.2: Default Port Settings

Parameter Value

Target device Console

Name xx-xx-xx Pn (last 3 octets of MAC address plus the port number)

Baud rate 9600

Bits per character 8

Parity None

Stop bits 1

Flow control None

Chapter 3: Operations 15

Time-out 15 minutes

CLI access character Use Server CLI setting (^D)

Power None

Most of these settings are standard serial port operating characteristics.

The CLI access character parameter specifies how you access the CLI. For more information, see
CLI Mode on page 26.

The Power parameter instructs the CCM appliance to monitor the state of a specified RS-232
control signal. Signal transitions may be configured to trigger SNMP traps. The parameter value
indicates an inbound control signal (CTS, DCD or DSR) and the state of that signal (low or high).
When the defined signal is true, the CCM appliance interprets it as a power on condition for the
attached device; when the signal is false, a power off condition for the device is assumed. The
signal specified for flow control may not be used for power control, and vice versa.

Port groups

The CCM appliance supports access control groups which may include one or more serial ports.
This feature allows a user account to be granted access to a group of ports using a single
specification. Each port may belong to only one group (but multiple ports may belong to the same

16 CCM Installer/User Guide

group). One or more port groups may then be specified in a user account. A group name may
contain up to eight characters.

Up to 8 port groups may be specified for a CCM850 appliance user, up to 16 port groups for a
CCM1650 appliance user and up to 48 port groups for a CCM4850 appliance user.

For example, assume that ports 1, 2, 3 and 4 are assigned to a group named LINUX. Ports 5, 6, 7
and 8 are assigned to a group named ROUTERS.

Users who must be able to access all Linux devices can be granted this right by having the LINUX
group specified in each of their user accounts. Those users will be able to access the devices
connected to ports 1, 2, 3 and 4.

Users who must be able to access Linux and router devices can be granted this right by having both
the LINUX and the ROUTERS groups specified in their user accounts. Those users will be able to
access the devices connected to ports 1 through 8.

To configure TD=console serial port settings:

Issue a Port Set command. You may specify settings for one port, multiple ports or all ports.

PORT [<port>|ALL] SET TD=CONSOLE [NAME=<name>] [BAUD=<baud>]
[SIZE=<size>] [PARITY=<parity>] [STOP=<stop_bits>] [FLOW=<flow_ctrl>]
[TIMEOUT=<time-out>] [SOCKET=<socket>] [CHAR=^<cli_char>]
[TOGGLE=NONE|DTR] [POWER=<signal>] [GROUP=<group>]

For more information and descriptions of all valid parameters, see Port Set command on page 61.

To configure TD=SPC ports and settings:

Issue a Port Set command with the TD=SPC parameter.

PORT <port> SET TD=SPC [NAME=<name>] [GROUP=<group>]

When a port is configured for an SPC power control device, you may specify only the Name and
Group parameters; no other serial port settings may be specified with the Port Set command.
However, you may use the SPC command to change certain configuration values for the SPC device.

SPC <port>|ALL [MINLOAD=<amps>] [MAXLOAD=<amps>]

Use an SPC Socket command to configure or control the state of the sockets on the SPC device.

SPC <port>|ALL [SOCKET <socket>] [WAKE=ON|OFF] [ONMIN=<time>]
[OFFMIN=<time>] [POWER=ON|OFF|REBOOT]

For more information, see SPC Command on page 85 and SPC Socket Command on page 85.

NOTE: Users who wish to use the native command interfaces of the SPC device should specify TD=console.

To display serial port settings:

Issue a Show Port command.

SHOW PORT [<port>|ALL|NAMES|GROUPS]

When you request information about a port configured as TD=console, the display includes
configuration information, current power status (if power status monitoring has been enabled), plus

transmit, receive and error counts. When you request information about a single port and a user is
currently accessing that port, the display also includes the username, access rights and other
information about the current session.

When you request information about a single port configured as TD=SPC, the display includes
information configured with the SPC command. A Show Port All command will indicate which
ports are SPC ports.

The display for Show Port Names includes the port numbers and names. If a port’s name has not
been changed with a Port Set command, the logical name is displayed. The display for Show Port
Groups includes the port number and port group name, if assigned.

For more information, see Show Port command on page 77.

Connecting to Serial Devices

The CCM appliance offers several methods for connecting to attached serial devices: Telnet, serial
CLI , PPP and SSH.

You may use the session sharing feature to permit multiple concurrent connections to a port. See
Session sharing on page 23 for more information.

Connecting to devices using Telnet

Each CCM serial port is directly addressable through a unique TCP port that provides a connection
to the attached serial device.

Plain text (non-encrypted) Telnet connections are enabled by default. For information about
enabling both plain text Telnet and SSH connections, Enabling plain text Telnet and SSH
connections on page 23 and Server Security command on page 70.

You may access the CCM appliance and its ports using the AVWorks software Telnet client or
third party Telnet client applications. Third party Telnet applications may be used in combination
with AVWorks software or standalone.

Chapter 3: Operations 17

AVWorks software Telnet client

Each CCM appliance ships with the AVWorks cross-platform management application. AVWorks
software provides a convenient way to select a CCM appliance or an attached device and launch a
Telnet session to manage it.

AVWorks software includes a built-in Serial Console Viewer Telnet application that offers several
features not found in other Telnet clients. For maximum flexibility, AVWorks software allows you
to associate a unique Telnet client with each CCM port. AVWorks software also provides built-in
support for SSH2.

You may specify the built-in Telnet client or a third party Telnet client. For more information, see
the AVWorks Installer/User Guide.

18 CCM Installer/User Guide

Standalone third party Telnet clients

You may use third party Telnet clients to access the CCM appliance directly without
AVWorks software.

To connect to a device using Telnet:

Type

telnet, followed by the CCM appliance IP address and the appropriate TCP port, which by

default is 3000 plus the physical port number, in decimal format. (The TCP port number may be
changed for any CCM port.)

For example, the following Telnet command connects to the serial device attached to physical port
4 of the CCM appliance.

telnet 192.168.0.5 3004

If an authentication method other than None has been configured for the CCM appliance, you will be
prompted for a username and password. Once authentication completes, your connection is confirmed.
When you successfully connect to the serial device, you will see a display similar to the following.

Username: Myname
Password: ******
Authentication Complete
Connected to Port: 7 9600,8,N,1,XON/XOFF

If the authentication method is configured as None, you may Telnet and connect to a serial device
without entering credentials; however, credentials are always required when connecting to the
CCM CLI.

NOTE: When using AVWorks software, the configuration of the credential caching feature may affect whether
you are prompted for a username and password. See the AVWorks Installer/User Guide for more information.

Data entered at the Telnet client is written to the attached serial device. Any data received by the
CCM appliance from the serial device is output to your Telnet client.

Connecting to devices from the console port

You may connect to a serial device from the console port, using a local terminal or a local PC using
a terminal emulation program. If you connect an external modem to the console port, you may also
access devices through a remote terminal or PC that can dial into the external modem. For
information about modem connections, see Configuring and using dial-in connections on page 19
and Server CLI command on page 65.

To connect to a device from the console port:

1. Issue a Server CLI command, using the Connect parameter to enable the use of the Connect
command from the console port. (This need only be done one time.)

SERVER CLI CONNECT=ON

2. Issue a Connect command to the desired port.

CONNECT [<port>] [EXCLUSIVE]

The optional Exclusive parameter requests exclusive access to the port. This is valid only if the
port is not currently in use. See Session sharing on page 23 for more information.

If you do not specify a port, a menu will be displayed, listing the ports that are available for
serial connection. Enter a port number or name, or press
valid port is specified, a message Connected to port ... appears. This message includes the port
name plus the configured settings for baud, data bits, parity, stop bits and flow control.

3. To end a device session that was initiated with a Connect command, issue a Disconnect command.

DISCONNECT

For more information, see Server CLI command on page 65, Connect Command on page 53 and
Disconnect Command on page 54.

Configuring and using dial-in connections

You may attach an external modem to the console port for dial-in serial CLI access to the CCM
appliance. This may be used as a backup connection if the appliance is not accessible from the
network. It may also be used as a primary connection at remote sites that do not have Ethernet
network capability. The modem must be Hayes compatible.

To specify a modem initialization string:

1. Issue a Server CLI command, using the Modeminit parameter to specify the modem initializa­tion string.

SERVER CLI MODEMINIT=“<string>”

The string must be enclosed in quotes and must include at least the command settings ATV1
and S0=1, which cause the modem to issue verbose response strings and autoanswer the phone
on the first ring. For more information, see Server CLI command on page 65.

The modem initialization string is sent to the cabled modem when any of the following
conditions occur:

• CCM appliance initialization

• Detection of a transition of DSR from low to high

• Completion of a call when DCD changes from high to low

2. Upon successful modem connection, press the

Chapter 3: Operations 19

Enter to cancel the command. If a

Enter key until the login prompt appears.

To display modem configuration information:

Issue a Show Server CLI command.

For more information, see Show Server CLI command on page 81.

Using PPP

The CCM appliance supports remote PPP access using an autoanswer modem that answers calls
and establishes the PPP protocol with a dial-in client. You may establish Telnet or SSH
connections over PPP.

SHOW SERVER CLI

20 CCM Installer/User Guide

PPP dial-in may be used to access a remote CCM appliance that does not warrant a WAN (Wide
Area Network) link to the Ethernet interface. The PPP dial-in may also be used to access a subnet
containing remote devices in the event of a WAN link failure. In this case, the PPP provides an
alternate path to one or more remote devices.

To use PPP, you must configure a modem in autoanswer mode on the console port; see Configuring
and using dial-in connections on page 19. Once the PPP connection is established, you must launch
an application that connects to the CCM appliance or to one of its ports. The PPP connection is
only a communications interface to the CCM appliance.

The CCM appliance implements a PPP server that uses CHAP (Challenge Authentication
Protocol). Passwords are not accepted in the clear on PPP connections.

To enable or disable a PPP server on the console port:

1. To enable a PPP server on the console port, issue a Server PPP command with the Enable parameter.

SERVER PPP ENABLE LOCALIP=<local_ip> REMOTEIP=<rem_ip> [MASK=<subnet>]

You must specify local and remote IP addresses to be used for the CCM appliance and client
ends of the PPP connection respectively. You are prompted to confirm or cancel the changes.

2. To disable a PPP server, issue a Server PPP command with the Disable parameter.

SERVER PPP DISABLE

For more information, see Server PPP command on page 68.

To display PPP configuration information:

Issue a Show Server PPP command.

For more information, see Show Server PPP command on page 81.

Using SSH

The CCM console management appliance supports version 2 of the SSH protocol (SSH2). The
CCM SSH server operates on the standard SSH port 22. The shell for this connection provides a
CLI prompt as if you had established a Telnet connection on port 23. The shell request for this
connection is for CLI access.

SSH connections to specific serial ports may be made on TCP ports that are numbered with values
100 greater than the standard 30xx Telnet ports for the CCM appliance. For example, if port 7 is
configured for Telnet access on port 3007, then port 3107 will be a direct SSH connection for port

7. When SSH is enabled, Telnet port 23 connections will be accepted from other clients if the

Server Security command includes the Encrypt=SSH,None parameter, which indicates that both
SSH and plain text connections will be allowed. Connecting to Telnet port 23 may also be tunneled
through a connection to SSH port 22.

SHOW SERVER PPP

Chapter 3: Operations 21

SSH server keys

When SSH is enabled for the first time, all sessions are terminated and the CCM appliance
generates an SSH server key. The key generation process may take up to three minutes. The key is
computed at random and is stored in the CCM configuration database.

In most cases, the SSH server key should not be modified because most SSH clients will associate
the key with the IP address of the CCM appliance. During the first connection to a new SSH server,
the client will display the SSH server’s key. You will be prompted to indicate if it should be stored
on the SSH client. After the first connection, most SSH clients will validate the key when
connecting to the CCM appliance. This provides an extra layer of security because the SSH client
can verify the key sent by the server each time it connects.

When you disable SSH and later reenable it, you may either use the existing server key or compute
a new one. If you are reenabling the same server at the same IP address, it is recommended that you
use the existing key, as SSH clients may be using it for verification. If you are moving the CCM
appliance to another location and changing the IP address, you may wish to generate a new SSH
server key.

Authenticating an SSH user

SSH is enabled and disabled with the Server SSH command. When you enable SSH, you may
specify the authentication method(s) that will be used for SSH connections. The method may be a
password, an SSH key or both. A user’s password and SSH key are specified with a User Add or
User Set command. All SSH keys must be RSA keys. DSA keys are not supported.

Table 3.3 lists and describes the valid SSH authentication methods that may be specified with a
Server SSH command.

Table 3.3: SSH Authentication Methods

Method Description

SSH connections will be authenticated with a username/password. With this method,

PW (default)

KEY

PW|KEY or KEY|PW

a user’s definition must include a valid password in order for that user to authenticate
an SSH session.

SSH connections will be authenticated with an SSH key. With this method, a user’s
definition must include valid SSH key information in order for that user to
authenticate an SSH session. Key authentication is always local; RADIUS is not
supported. For more information, see SSH user keys on page 22.

SSH connections will be authenticated with either a username/password or an SSH
key. If a user has only a password defined, that user must authenticate an SSH
session with a username/password. If a user has only an SSH key defined, that user
must authenticate an SSH session using the key. If a user has both a password and
an SSH key defined, that user may use either a username/password or the SSH key
to authenticate an SSH session. This method allows the administrator to define how
each user will authenticate an SSH session based on information provided in the
User Add/Set command.
PW authentication will be local or RADIUS as specified in the Auth parameter of the
Server Security command. Key authentication is always local.

22 CCM Installer/User Guide

Table 3.3: SSH Authentication Methods (Continued)

Method Description

PW&KEY or KEY&PW

A user’s access rights are determined from the authentication method used. SSH key authentication
always uses the access rights from the local user database. Depending on the server authentication
mode specified with the Server Security command, SSH password authentication will use either the
access rights from the local user database or the values returned by the RADIUS server.

With either of the “or” methods (PW|KEY and KEY|PW), the user access rights are determined
from the method used to authenticate the user.

With either of the “and” methods (PW&KEY and KEY&PW), the user access rights are
determined from the first method specified. If PW&KEY is specified, the access rights from the
password authentication will be used. If KEY&PW is specified, the access rights from the key
authentication will be used.

For more information, see Using Authentication Methods on page 30.

SSH user keys

SSH connections will be authenticated using both a username/password and an
SSH key. With this method, a user’s definition must include a password and SSH key
information for that user to authenticate an SSH session.
PW authentication will be local or RADIUS as specified in the Auth parameter of the
Server Security command. Key authentication is always local.

A user’s SSH key is specified in a User Add or User Set command. You may define a key even if
SSH is not currently enabled. The key may be specified in one of two ways:

• When using the SSHKEY and FTPIP keyword pair to define the network location of a user’s
SSH key file, the SSHKEY parameter specifies the name of the uuencoded (Unix to Unix
encoded) public key file on an FTP server. The maximum file size that can be received is 4K
bytes. The FTPIP parameter specifies the FTP server’s IP address.

When this method is specified, the CCM appliance initiates an FTP client request to the
specified IP address. The CCM appliance then prompts the user for an FTP username and
password for connection. When connected, the CCM appliance will GET the specified key file
and the FTP connection will be closed. The CCM appliance then stores the SSH key with the
username in the CCM user database.

• When using the KEY keyword to specify the SSH key, the KEY parameter specifies the actual
uuencoded SSH key. This is for configurations that do not implement an FTP server. The CCM
appliance stores the specified key in the CCM user database.

The CCM appliance processes a uuencoded SSH2 public key file with the format described in the
IETF document draft-ietf-secshpublickeyfile-02. The key must follow all format requirements. The
UNIX ssh-keygen2 generates this file format. The CCM appliance also processes a uuencoded
SSH1 public key file. The UNIX ssh-keygen generates this file format.

Chapter 3: Operations 23

To enable SSH session access to the CCM appliance:

1. Issue a Show Server Security command to ensure that you are using an authentication method
other than None.

SHOW SERVER SECURITY

2. Issue a Server SSH command with the Enable parameter. You may also specify an authentica­tion method.

SERVER SSH ENABLE AUTH=<auth>

If an authentication method is not specified, the previous authentication parameter will be
used. The default value is AUTH=PW.

3. If you are enabling SSH for the first time, you are advised that all other CCM appliance
sessions will be terminated. Enter

4. If you are reenabling SSH, you are prompted to use the existing SSH server key or generate a
new key. Enter

For more information, see Server SSH command on page 75.

To disable SSH session access to the CCM appliance:

Issue a Server SSH command with the Disable parameter.

SERVER SSH DISABLE

When SSH is disabled, the CCM appliance operates in plain text mode.

Y to use the existing key or N to generate a new key.

Y to continue or N to cancel.

To display SSH information:

Issue a Show Server Security command.

SHOW SERVER SECURITY

If SSH is enabled, the display will include SSH2. Regardless of whether SSH is enabled, the
display will indicate the authentication method that was specified with the Server SSH command.

Enabling plain text Telnet and SSH connections

Plain text (non-encrypted) Telnet connections are enabled by default.

If you enable SSH connections using the Server Security command and the Encrypt=SSH
parameter, plain text Telnet connections will be disabled. However, if you enable SSH connections
with the Server SSH command, both plain text and SSH connections will be allowed.

To enable both Telnet and SSH connections:

Issue a Server Security command, indicating Encrypt=SSH,None.

Session sharing

Session sharing allows multiple concurrent sessions to the same attached device.

• The CCM850 appliance allows up to 16 total concurrent sessions, with up to four concurrent
sessions per port.

24 CCM Installer/User Guide

• The CCM1650 appliance allows up to 32 total concurrent sessions, with up to four concurrent
sessions per port.

• The CCM4850 appliance allows up to 96 total concurrent sessions, with up to four concurrent
sessions per port.

You may:

• Disable sharing. In this case, only one session per port may be active at a time.

• Enable automatic session sharing. In this case, a user will automatically be connected to a port
even if it is in use (with restrictions noted in the following examples).

• Enable session sharing with the query option. In this case, when a port is in use, the session
originator (the user who initiated the first session) must grant permission before other users are
able to join a session on that port.

Session sharing and the preemption of device sessions are also affected by a user’s configured
access level. There are three access levels, with the following hierarchy:

Appliance Administrator > Administrator > User

For example, assume user A is currently accessing a device, and user B wishes to access the same
device. If user B’s access level is equal to or higher than user A’s access level, then user B may be
allowed to preempt user A’s device session. See Access levels on page 29 for more information.

Any user may also request exclusive access to a port if there is no other existing connection to that
port. This is done on the login screen by adding the E parameter after the username or by adding the
Exclusive parameter with the Connect command.

The following examples show the interaction between share mode and access levels.

Session sharing examples

These examples illustrate session sharing and preemption for one port and two users. Assume this
port is currently in use by the session originator (SO). Another user, the requesting user (RU),
wants to connect to the same port. For simplicity, also assume that if RU is allowed to connect, it
will not exceed the maximum allowable number of sessions per port or sessions per appliance.

Example 1 - SO’s access level is higher than RU’s access level.

Share mode = Query
SO is connected non-exclusively

SO will be prompted to approve sharing the connection.

If SO approves, then RU will be connected to the port.
If SO does not approve, then RU will not be connected to the port.

Share mode = Query
SO is connected exclusively

RU will not be connected to the port.

Share mode = Disabled or Auto

RU will not be connected to the port. (In this case, it does not matter whether SO is connected
exclusively or non-exclusively.)

Chapter 3: Operations 25

Example 2 - RU’s access level is equal to or higher than SO’s access level

Share mode = Disabled

-or-

SO is connected exclusively

RU is prompted with preemption choices E, N and D.

If RU replies with

E, then SO will be preempted/disconnected and RU will be connected

exclusively to the port.

If RU replies with

N, then SO will be preempted/disconnected and RU will be connected

non-exclusively to the port.

If RU replies with

D, SO will remain connected and RU will not be connected to the port.

Share mode = Auto or Query
SO is connected non-exclusively

RU is prompted with preemption choices E, N, S and D.

If RU replies with

E, then SO will be preempted/disconnected and RU will be connected

exclusively to the port.

If RU replies with

N, then SO will be preempted/disconnected and RU will be connected

non-exclusively to the port.

If RU replies with

S and Share Mode = Auto, SO will remain connected and RU will be

connected to the port.

If RU replies with

S and Share Mode = Query, SO will be prompted to approve sharing

the connection.

If SO approves, RU will be connected to the port.

If SO does not approve, RU will not be connected to the port.

If RU replies with

D, SO will remain connected and RU will not be connected to the port.

Example 3 - Ending shared sessions

In a shared session, if the SO quits the session, the next user sharing the session will become the
SO. If the SO is logged out by another user, all sessions that are shared with the SO will be
terminated, as well as the SO’s session.

To enable/disable session sharing:

To disable session sharing, issue a Server Share command with the Disable parameter.

-or-

To enable automatic sharing, specify the Auto parameter.

-or-

To enable sharing only with the permission of the session originator, specify the Query parameter.
This is the default value.

26 CCM Installer/User Guide

To initiate a device session with exclusive access:

At the Username: prompt, enter your username, followed by an

-or-

If device connections from the console port are enabled, enter a Connect command, followed by a
port number or name, then the Exclusive parameter.

NOTE: A request for an exclusive connection is valid only when there are no other users currently using the port.

To display share mode information:

Issue a Show Server command. The display will indicate the share mode.

CLI Mode

While you are connected to an attached serial device, you may enter CLI mode and enter CCM
appliance commands.

To enter or exit CLI mode when connected to a serial device:

1. To enter CLI mode, type the CLI access character, which is
prompt (>), you may enter CCM commands.

2. To exit CLI mode and return to the session with the attached device, issue a Resume command.

RESUME

For more information, see Resume Command on page 64.

To change the CLI access character:

Issue a Server CLI command or a Port Set command, using the Char parameter to specify the CLI
access character.

SERVER CLI CHAR=^<char>

- or ­PORT SET CHAR=^<char>

If you issue a Port Set command with Char=None, then the CLI access character specified in the
Server CLI command will be used. You may use the Port Set command to override the Server CLI
access character on a per-port basis.

For more information, see Server CLI command on page 65 and Port Set command on page 61.

Ctrl-D by default. At the CLI

To display CLI access character information:

Issue a Show Server CLI command.

SHOW SERVER CLI

For more information, see Show Server CLI command on page 81.

Ending Device Sessions

To end your session:

Enter CLI mode and issue a Quit command.

- or -

If you initiated the device session with a Connect command, enter CLI mode and issue a
Disconnect command.

- or -

Allow the port to time-out due to inactivity. In this case, a notification message is issued and the
serial CLI session returns to CLI mode. This time-out may occur while you are in CLI mode.

- or -

For modem connections, if a carrier drop occurs, the serial CLI session is automatically logged off.

If you end a shared session and you were the session originator, the next user sharing the session
becomes the session originator.

For more information, see Quit Command on page 64 and Disconnect Command on page 54.

To end another user’s session:

Issue a User Logout command, specifying the name of the user to be logged out.

A message is sent and the connection is dropped.

If you are logged out by another user during a shared session and you are the session originator, all
the sessions that share with you will also be logged out.

For more information, see User Logout command on page 88. For information about session
sharing, see Session sharing on page 23.

Chapter 3: Operations 27

Session time-out

The CCM console management appliance monitors data traffic when you are connected to an
attached serial device. You may specify a time-out value with the Server CLI command. You may
also specify a time-out value for each port with the Port Set command. When no data is received
from the connected user for the configured number of minutes, the connection is terminated.

The following time-out values are used:

• For a Telnet session, the Server CLI time-out value is used.

• For a serial port session, if the port’s configured time-out value is zero, the Server CLI time­out value is used, even if it is also zero.

• For a serial port session, if the port’s configured time-out value is non-zero, that value is used.

Managing User Accounts

The CCM user database can store information for up to 64 user accounts.

28 CCM Installer/User Guide

To add a user:

Issue a User Add command.

USER ADD <username> [PASSWORD=<pwd>] [SSHKEY=<keyfile>] [FTPIP=<ftpadd>]
[KEY=<sshkey>] [ACCESS=<access>] [GROUP=<group1>[,<group2>...]]

You must specify a username. You must also specify a password or SSH user key information, or
you may specify both. You may also include an access level/access rights and group names. For
more information, see Using SSH on page 20, Access rights and levels on page 28, User Add
command on page 87 and Port groups on page 15.

To change a user’s configuration information:

Issue a User Set command.

USER SET <username> [PASSWORD=<pwd>] [SSHKEY=<keyfile>] [FTPIP=<ftpadd>]
[KEY=<sshkey>] [ACCESS=[+|–]<access>] [GROUP=[+|–]<group1>[,<group2>...]]

You may change your own password at any time. You must have USER access rights to change
another user’s password or to change any user’s SSH user key information and access rights.

To remove an SSH user key or password, specify Key=“” or Password=“”. You cannot remove
both the password and the SSH key from a user’s definition; one must remain in the user database.
Also, you cannot remove a user’s key or password if that removal would result in no valid users
having USER access rights.

For more information, see Using SSH on page 20, Access rights and levels on page 28 and User Set
command on page 89.

To delete a user:

Issue a User Delete command.

USER DELETE <username>

For more information, see User Delete command on page 88.

To display user configuration information:

1. To display information about one user, issue a Show User command, specifying the username.

SHOW USER <username>

2. To display information about all users, issue a Show User command with the All parameter.

SHOW USER ALL

For more information, see Show User command on page 83.

Access rights and levels

Most CCM appliance commands require the user to have the appropriate permission to issue CCM
appliance commands. Permissions are expressed as access rights or access levels. The access
rights/levels for each command are listed in Table 4.4 on page 47. Table 3.4 describes the access
rights a user may be given.

Table 3.4: Access Rights

Access Right Description

Chapter 3: Operations 29

PCON

SCON

SMON

USER

BREAK

P

The Port Configuration access right allows the user to modify port settings. Grant PCON
access only to users who need to issue the Port Set command.

The Server Configuration access right allows the user to change the CCM configurations,
including setting the IP address and updating the program load in FLASH. Grant SCON
access only to users who need to administer the CCM appliance.

The Server Monitor access right allows the user to view CCM appliance status and
monitor serial port activity. Grant SMON access only to users who need to assist other
users in accessing attached serial devices.

The USER access right allows the user to modify the user database. Grant USER access
only to users who need to add users, change user specifications or delete users. At least
one user must have USER access rights; otherwise, the user database cannot be changed.

The BREAK access right allows the user to send a serial break sequence to the attached
serial device. On certain devices, this sequence has a special meaning. Grant BREAK
access only to users who need to use the Port Break command.

The Port access right gives a user access to one or more serial ports and the attached
serial devices. You may grant Port access rights to specific ports (Pn), a range of ports
(Px-y) or all ports (PALL).

Access levels

When you specify a user’s permissions, you may either indicate the individual rights as listed in
Table 3.4 or you may indicate a predefined access level. The APPLIANCEADMIN and ADMIN
levels are equivalent to the following individual specifications:

• The APPLIANCEADMIN level is equivalent to PALL, USER, SCON, SMON, PCON
and BREAK

• The ADMIN level is equivalent to PALL, USER, SMON, PCON and BREAK

The third level (that is, not APPLIANCEADMIN or ADMIN) is user. For preemption purposes, the
following hierarchy is used: APPLIANCEADMIN > ADMIN > user.

Session sharing is affected by access levels; see Session sharing on page 23 for more information.

To manage a user’s access rights/levels:

1. To configure a user’s access rights/level, issue a User Add command, using the Access param­eter to specify the rights or a level.

USER ADD <username> ACCESS=<access>

2. To change a user’s access rights/level, issue a User Set command, using the Access parameter
to specify the rights or a level.

USER SET <username> ACCESS=<access>

30 CCM Installer/User Guide

3. To display the access rights and level for one or all users, issue a Show User command.

SHOW USER <username>|ALL

For more information, see Managing User Accounts on page 27 plus User Add command on
page 87, User Set command on page 89 and Show User command on page 83.

Using Authentication Methods

The CCM appliance supports several methods for authenticating users: local, RADIUS and none.
Multiple connection and authentication methods may operate concurrently. By default,
authentication is performed at the local CCM user database.

Local authentication

Local authentication uses the CCM appliance internal user database to authenticate users. You may
optionally specify both local and RADIUS authentication, in either order. In this case,
authentication will be attempted initially on the first method specified. If that fails, the second
method will be used for authentication.

RADIUS authentication

RADIUS authentication uses an external third party RADIUS server containing a user database to
authenticate CCM appliance users. The CCM appliance, functioning as a RADIUS client, sends
usernames and passwords to the RADIUS server. If a username and password do not agree with
equivalent information on the RADIUS server, the CCM appliance is informed and the user is denied
CCM access. If the username and password are successfully validated on the RADIUS server, the
RADIUS server returns an attribute that indicates the access rights defined for that username.

To use RADIUS authentication, you must specify information about the primary RADIUS server
and optionally, a secondary RADIUS server to be used as a backup.

The RADIUS server definition values specified in CCM appliance commands must match
corresponding values configured on the RADIUS server. On the RADIUS server, you must include
CCM appliance-specific information: the list of valid users and their access rights for the CCM
appliance. Each user-rights attribute in the RADIUS server’s dictionary must be specified as a
string containing the user’s access rights for the CCM appliance, exactly matching the syntax used
in the CCM User Add command.

Consult your RADIUS administrator’s manual for information about specifying users and their
attributes. The exact process depends on the RADIUS server you are using.

You may optionally specify both RADIUS and local authentication, in either order. In this case,
authentication will be attempted initially on the first method specified. If that fails, the second
method will be used for authentication.

When port group names are used, the CCM appliance will parse group names coming from a
RADIUS server, and allow access according to group content.

No authentication

When authentication is disabled, users are not authenticated. Telnet sessions to serial ports are
accepted immediately, and users are not prompted for a username or password. In this case, users
are granted access only to the port to which they are connected, including Break access.

Connections to the Telnet port (23), serial CLI and PPP are still authenticated using the local CCM
user database, even when authentication is expressly disabled. Generally, these communications
paths are used only by administrators, and authentication is enforced in order to establish
appropriate access rights.

Authentication may not be disabled when SSH session access is enabled.

Authentication summary

Table 3.5 indicates how authentication is performed according to the authentication method
specified and the type of connection to the CCM appliance.

Table 3.5: Authentication Method Summary

Mode Connection Type and Authentication Action

Local All sessions are authenticated using the CCM user database.

Chapter 3: Operations 31

None

Telnet and SSH sessions are authenticated using RADIUS. Serial CLI sessions are
authenticated using the CCM user database.

Telnet and SSH sessions are authenticated using the CCM user database. If that
fails, authentication uses RADIUS. Serial CLI sessions are authenticated using the
CCM user database.

Telnet and SSH sessions are authenticated using RADIUS. If that fails,
authentication uses the CCM user database. Serial CLI connections are
authenticated using the CCM user database.

Telnet to serial port sessions use no authentication. Telnet CLI and serial CLI
sessions are authenticated using the CCM user database. This authentication mode
cannot be used for SSH connections.

To specify the authentication method:

1. For RADIUS authentication, issue a Server RADIUS command.

SERVER RADIUS PRIMARY|SECONDARY IP=<radius_ip> SECRET=<secret> USER­RIGHTS=<attr> [AUTHPORT=<udp>] [TIMEOUT=<time-out>] [RETRIES=<retry>]

You must specify the server’s IP address, the UDP port to be used and a “secret” to be used.
You must also specify a user-rights attribute value that matches a value in the RADIUS
server’s dictionary.

You may also use this command to delete a RADIUS server definition.

SERVER RADIUS PRIMARY|SECONDARY DELETE

For more information, see Server RADIUS command on page 69.

32 CCM Installer/User Guide

2. Issue a Server Security command, using the Authentication parameter to specify the
authentication method. Use the Encrypt parameter to enable plain text Telnet connections,
SSH connections or both.

SERVER SECURITY AUTHENTICATION=<auth> ENCRYPT=<conns>

You may optionally specify both RADIUS and local authentication, in either order. In tis case,
authentication will be attempted initially on the first method specified. If that fails, the second
method will be used for authentication.

When SSH session access is enabled, you must specify an authentication mode other than None.

3. You are prompted to save the information. Enter

To display authentication configuration information:

1. Issue a Show Server Security command.

SHOW SERVER SECURITY

The display includes the current CCM appliance authentication settings that were configured
with the Server Security command. If SSH access has been enabled, the display indicates
SSH2. Regardless of whether SSH is enabled, the display includes the authentication method
specified with the Server SSH command.

2. To display CCM RADIUS settings that were configured with the Server RADIUS command,
issue a Show Server RADIUS command.

SHOW SERVER RADIUS

For more information, see Server Security command on page 70, Show Server Security command
on page 82, Show Server RADIUS command on page 81 and Using SSH on page 20.

Y to confirm or N to cancel.

Using security lock-out

When the security lock-out feature is enabled, a user account will be locked-out after five
consecutive authentication failures. A successful authentication will reset the counter to zero. You
may configure a lock-out period of 1-999 hours. A lock-out period of zero disables the feature; that
is, user accounts will not be locked-out.

A locked account will remain locked until the specified time elapses, the CCM appliance is power­cycled or the account is unlocked by an administrator with the User Unlock command. A user with
the ADMIN access level may unlock all users except a user with the APPLIANCEADMIN level. A
user with the APPLIANCEADMIN level may unlock all users.

To enable or disable security lock-out:

1. To enable security lock-out, issue a Server Security command, using the Lockout parameter
with a value between 1-999.

2. To disable security lock-out, issue a Server Security command, using the Lockout=0 parameter.

To unlock a locked-out user:

Issue a User Unlock command with the username.

Managing Port History

Each CCM appliance serial port has a circular history buffer that contains the latest 64K bytes of data
received from the attached serial device. You may enable the NFS feature, which will write buffered
data to a file on an NFS server. Port history information may be useful for auditing and troubleshooting.

Using the local history buffer

The history buffer begins filling with data received from attached devices upon completion of
CCM appliance initialization, even if no user is connected. When you connect to a serial port, the
data that was received from the attached serial device prior to the connection is available in the
buffer. Once online, new data continues to be stored in the buffer. You may choose whether to
display the history buffer’s content automatically when you connect and whether to keep or discard
the history buffer’s content at the end of a session.

When more than 64K bytes of data are sent to the history buffer, data at the top of the buffer is
discarded to make room for the new data. As a result, the buffer always contains the most recent
64K bytes of port history.

Using port history mode commands

Once you are in port history mode, you may issue the commands listed in Table 3.6. Only the first
letter of the command is required.

Chapter 3: Operations 33

Table 3.6: Port History Mode Commands

Command Description

Bottom B sets the view location to the bottom of the file minus 23 history display lines, if available.

Clear C clears the port history buffer.

Help H displays a summary of the port history commands.

Quit Q returns to the normal CLI.

Resume

N increments the current history display line by the number of lines per page and outputs a

new history display page.

P decrements the current history display line by the number of lines per page and outputs a
new history display page.

R leaves port history mode and CLI mode and resumes the session with the attached serial device.
This single command is equivalent to sequentially using the Quit and Resume commands.

34 CCM Installer/User Guide

down from the current line toward the bottom of the buffer. The search direction remains in
effect for subsequent searches until you change the search direction.
If the string is found, the current history display line is set to the line containing the string, and
the unit outputs a history display page. If the string is not found, an error message is displayed,
no other information is output and the current history display line is not changed.
Entering the Search command with no parameters searches again for the previous string in the
same direction as the previous search.

The following examples assume the user is in port history mode.

The following command searches the history buffer in the upward direction for the string
Abort Process.

PORT HISTORY> s -u “Abort Process”

The following command searches the history buffer for the string Process, ignoring case.

-i before the string. To specify

-u to search up from the current line toward the top of the buffer or -d to search

To access port history mode:

Issue a Port History command.

PORT HISTORY

The PORT HISTORY > prompt appears.

To control the port history buffer display when you connect:

Issue a Server CLI command, using the History parameter to specify the Hold or Auto option:

SERVER CLI HISTORY=HOLD|AUTO

• If Hold is specified, the number of bytes in the history buffer is displayed, but none of the his­tory data is output. In this case, you must access the CLI and use the Port History command to
view the port’s history buffer content. This is the default mode.

• If Auto is specified, the number of bytes in the history buffer is displayed and the entire con­tent of the buffer is output to the Telnet session. In this mode, the history buffer’s content may
be reviewed in the Telnet client’s scrolling window. You may also use the Port History com­mand to view the port’s history buffer content.

To control the port history buffer content when you end a session:

Issue a Server CLI command, using the History parameter to specify the Clear or Keep option:

SERVER CLI HISTORY=CLEAR|KEEP

• If Clear is specified, the port history buffer is cleared and all data is discarded at the end of a session.

• If Keep is specified, the port history buffer’s content is retained at the end of a session.

To clear and discard all data in a port history buffer:

Issue a Clear command while you are in port history mode.

CLEAR

- or -

Issue a Server CLI command, indicating History=Clear.

SERVER CLI HISTORY=CLEAR

In this case, the port’s history buffer is cleared at the end of each device session.

NFS history files

When the NFS feature is enabled on the CCM appliance and on a port, port history data is written
to a file on an NFS server, in addition to the local history buffer on the CCM appliance. Each serial
port has its own file(s) on the NFS server where data is written. The NFS server must support
NFSv3 (RFC1813).

Timestamps

Timestamps are written to the history file in the format: YYYY-MM-DD HH:MM:SS, where the
hour (HH) is in 24-hour format. Each timestamp is preceded and followed by a carriage return and
linefeed (
assumed to be UTC (Universal Coordinated Time). You may display the current time on the CCM
appliance at any time by entering a Show Server command.

A timestamp is inserted at the beginning of the file and whenever the file is opened for data to be
written, but not more frequently than once every second.

If the CCM appliance is unable to send incoming data to the NFS server file quickly enough (for
example, due to network load or server speed), an overrun may occur in the history accumulation
buffer, and older data will be discarded to accommodate new incoming data. If this occurs, the
location in the history file where the data was lost will indicate <<data lost due to overrun>>
appended to the timestamp.

CR+LF). The timestamp date/time uses the current time on the CCM appliance, which is

Chapter 3: Operations 35

Enabling NFS on the CCM appliance

To use NFS, you must first enable NFS on the CCM appliance by identifying the address and
mount point of the NFS server, plus the file type and the protocol.

NOTE: The NFS server’s system administrator must make the appropriate configuration changes to allow the
CCM appliance to access a specific subdirectory in the NFS server’s file system (the mount point). This may or
may not allow the CCM appliance to access and/or create subdirectories within the mounted subdirectory. This
will affect what may be specified in the Port NFS command’s file parameter.

36 CCM Installer/User Guide

The valid file types are:

• Linear - A file will be opened for writing at the end (appended); this is the default

• Daily - A new file will be created every midnight

By default, the TCP network protocol is used for communications between the CCM appliance and
the NFS server. You may use the Protocol parameter to specify the UDP or TCP protocol.

To enable/disable NFS on the CCM appliance:

1. To enable NFS on the appliance, issue an NFS command with the Enable parameter.

NFS ENABLE [IP=<nfs_server>] [MOUNT=<mount>] [FTYPE=LINEAR|DAILY]
[PROTOCOL=TCP|UDP]

If this is the first time you are enabling NFS on the appliance, you must include the IP address
of the NFS server and a valid mount point. You may also specify the file type and protocol.

You may also use the NFS Enable command to change the current IP address, mount point, file
type or protocol.

The values will be displayed and you will be prompted to confirm.

If a mount operation is not immediately successful, it will be retried every 60 seconds for
approximately 15 minutes. If an existing mount is lost, the CCM appliance will automatically
attempt to restore it.

If an error occurs, the display may include a numeric value and a text message. See NFS Error
Codes and Port Status on page 105 for descriptions.

2. To disable NFS, issue an NFS command with the Disable parameter.

NFS DISABLE

If you later enable NFS again on the appliance, the server address, mount point, file type and
protocol values at the time of disabling will be used if new values are not specified with the
enable command.

For more information, see NFS Command on page 54.

To check the NFS mount status:

Issue a Show NFS command. (You may also issue the NFS Enable command without additional
parameters to verify an existing mount.)

Enabling NFS on the CCM appliance ports

After NFS is successfully enabled on the CCM appliance, you may enable and configure NFS on
the individual ports.

If an error occurs, it may include a numeric value and a text message. See NFS Error Codes and
Port Status on page 105 for descriptions.

NFS filenames

When you enable NFS on one or all ports, you may specify a filename, which must be unique for
each port. If the daily file type was configured with the NFS Enable command, the filename must

Chapter 3: Operations 37

be also be unique for each day. You may use the substitution strings listed in Table 3.7 as part of
the filename specification, regardless of the file type.

Table 3.7: Substitution Strings in NFS Filename Specification

2-Character String Substituted Value Example (Port 7 on January 8, 2004)

%d Day of month (01-31) 08

%D Same as %m-%d-%y 01-08-04

%F

%j Julian day of year (001-366) 008

%m Month (01-12) 01

%y Year without century (00-99) 04

%Y Year with century (2004-9999) 2004

%# Port number (01-nn) 07

%% % %

Same as %Y-%m-%d
(this is the ISO 8601 date format)

2004-01-08

If you do not specify a filename, the default is interpreted according to the configured file type:

• If the file type is linear, the default is equivalent to P%#.hst. The resulting filename for each
port will include the port number.

• If the file type is daily, the default is equivalent to P%#_%F.hst. The resulting daily filename
for each port will include the port number and the date.

Using the default filenames is the most convenient way to ensure that all filenames will be unique
for each port (and for each day, if the file type is daily).

However, if you choose to specify a filename rather than use the defaults, it must meet the
following criteria:

• The filename must be different from the filename specified for any other port on the CCM
appliance. Using the port number substitution string (%#) in the filename specification is one
way to accomplish this.

If you are enabling NFS on all ports by including the All parameter, and you also include the
File parameter with a nondefault specification (that is, a specification other than File=), the
filename specification must explicitly include the %# port number substitution string.

• If the file type is daily, the filename specification must also include one or more of the date
substitution strings so that the resulting filename is different each day.

If you specify a nondefault filename, and later wish to use the default filename, you may change it
by issuing a Port NFS Enable command with a File= or File=”” parameter.

38 CCM Installer/User Guide

If you specify a nondefault filename, and later attempt to change the file type from linear to daily,
the request will be rejected if the filename specification does not include a date substitution string.

When writes will occur

When you enable NFS on a port, you may configure a buffer size and a time interval, which will be
used to determine when accumulated data is written to the NFS server file.

• If you configure a buffer size of zero bytes and a time interval of zero seconds, data will be
written to the file as soon as the data is available (not to exceed one write per second).

• If you configure a buffer size of zero bytes and a non-zero time interval, accumulated data will
be written to the file each time the specified interval elapses (unless 3584 or more bytes accu­mulate in the buffer before an interval elapses, in which case the data will be written then).

• If you configure a non-zero buffer size and a time interval of zero seconds, data will be written
when the specified number of bytes has accumulated, regardless of elapsed time. (If you con­figure a size value larger than 3584, the data will be written whenever 3584 or more unwritten
bytes accumulate.)

To display NFS configuration information and mount status:

Issue a Show NFS command. The display will include the status of the mount operation. For more
information, see Show NFS command on page 76.

SHOW NFS

To enable/disable and configure NFS on a port:

1. To enable NFS on one or all ports, issue a Port NFS command with the Enable parameter.

PORT <port>|ALL NFS ENABLE [FILE=<file>] [SIZE=<bytes>] [TIME=<sec>]

You may specify a filename or use default values; see NFS filenames on page 36.You may also
configure size and time thresholds; see When writes will occur on page 38.

2. To disable NFS on one or all ports, issue a Port NFS command with the Disable parameter.

PORT NFS DISABLE

For more information, see Port NFS command on page 60.

To display NFS port history file information:

Issue a Show Port command. The display includes the current port NFS status, which covers the
most recent 15 minutes or since NFS history was most recently enabled for that port.

SHOW PORT

-or-

Issue a Show NFS command. In addition to displaying the current NFS mount status, this command
will also show any port error status other than No Recent Errors Detected.

SHOW NFS

NFS Error Codes and Port Status on page 105 describes the error codes that may be displayed.

Managing the CCM Appliance Using SNMP

The CCM console management appliance provides a set of commands that create and manage
SNMP structures for use by third party network management products. These commands cover the
following operations:

• Enabling and disabling SNMP UDP port 161 SNMP processing

• Defining read, write and trap community names

• Defining and deleting up to four SNMP management entity IP addresses

• Enabling and disabling SNMP traps

• Defining and deleting up to four trap destination IP addresses

• Defining, copying and deleting up to ten alert strings for each port

By default, SNMP is enabled but no traps are enabled and no trap destinations are defined.

To enable or disable SNMP processing:

1. To enable SNMP processing, issue a Server SNMP command with the Enable parameter. This
is the default setting.

SERVER SNMP ENABLE

2. To disable SNMP processing, issue a Server SNMP command with the Disable parameter.

SERVER SNMP DISABLE

For more information, see Server SNMP command on page 72.

Chapter 3: Operations 39

To specify SNMP community names:

Issue a Server SNMP Community command, using the Readcomm, Writecomm and Trapcomm
parameters to specify community names.

NOTE: The default community names are “public”; if you enable SNMP, you are encouraged to change the
community values to prevent access to the MIB.

SERVER SNMP COMMUNITY READCOMM=<name> WRITECOMM=<name>
TRAPCOMM=<name>

Although all three community names default to public, if you specify a trap community name with
this command, it must be different from the read and write community names.

For more information, see Server SNMP Community command on page 73.

To add or delete SNMP management entity addresses:

1. To add an SNMP management entity address, issue a Server SNMP Manager command with
the Add parameter and the management entity’s IP address. You may define up to four SNMP
management entity addresses, using separate commands.

SERVER SNMP MANAGER ADD <ip_address>

40 CCM Installer/User Guide

When you define at least one SNMP manager, SNMP requests are processed if they are from
one of the defined SNMP managers. If a request is not from one of the defined SNMP
managers, the SNMP request is discarded.

2. To delete an SNMP management entity address, issue a Server SNMP Manager command with
the Delete parameter and the management entity’s IP address.

SERVER SNMP MANAGER DELETE <ip_address>

If no management entities are defined, any SNMP manager may access the MIB. For more
information, see Server SNMP Manager command on page 73.

To enable or disable SNMP traps:

1. To enable SNMP traps, issue a Server SNMP Trap command with the Enable parameter.

SERVER SNMP TRAP ENABLE

The CCM appliance will display a numbered list of traps that are currently disabled with a
prompt requesting you to select trap(s) to enable. Indicate the traps to be enabled by entering a
trap’s list number, several numbers separated by commas, a range of numbers separated by a
dash or a combination of numbers with commas and dashes. To enable all traps, type
cancel the command, press

- or ­To enable all SNMP traps, issue a Server SNMP Trap command with the Enable and All
parameters. In this case, the numbered list is not displayed.

SERVER SNMP TRAP ENABLE ALL

2. To disable SNMP traps, issue a Server SNMP Trap command with the Disable parameter.

SERVER SNMP TRAP DISABLE

The CCM appliance will display a numbered list of traps that are currently enabled with a
prompt requesting you to select trap(s) to disable. Indicate the traps to be disabled by entering
a trap’s list number, several numbers separated by commas, a range of numbers separated by a
dash or a combination of numbers with commas and dashes. To disable all traps, type
cancel the command, press

- or ­To disable all SNMP traps, issue a Server SNMP Trap command with the Disable and All
parameters. In this case, the numbered list is not displayed.

SERVER SNMP TRAP DISABLE ALL

For more information, see Server SNMP Trap command on page 74 and Supported Traps on
page 100.

ALL. To

Enter.

ALL. To

Enter.

To add or delete SNMP trap destination addresses:

1. To add an SNMP trap destination address, issue a Server SNMP Trap Destination command
with the Add parameter and the destination’s IP address. You may define up to four destination
addresses, using separate commands.

SERVER SNMP TRAP DESTINATION ADD <ip_address>

Chapter 3: Operations 41

2. To delete an SNMP trap destination address, issue a Server SNMP Trap Destination command
with the Delete parameter and the destination’s IP address.

SERVER SNMP TRAP DESTINATION DELETE <ip_address>

For more information, see Server SNMP Trap Destination command on page 75.

To add, copy or delete port alert strings:

1. To add a port alert string, issue a Port Alert Add command, specifying the port and a 3-32
character string. You may define up to ten strings for each port, using separate commands.

The alert string will only generate a trap if the PortAlert trap is enabled with a Server SNMP
Trap command.

PORT <port> ALERT ADD “<string>”

2. To delete a port alert string, issue a Port Alert Delete command, specifying a port.

PORT <port> ALERT DELETE

The CCM appliance displays a numbered list of alert strings that have been defined for the
specified port with a prompt requesting you to select alert string(s) to delete. Indicate the alert
strings to be deleted by entering an alert string’s list number, several numbers separated by
commas, a range of numbers separated by a dash or a combination of numbers with commas
and dashes. To delete all alert strings, type

ALL. To cancel the command, press Enter.

3. To copy the defined alert strings from one port to another port, issue a Port Alert Copy com­mand, specifying the ports to be copied to and from.

PORT <to_port> ALERT COPY <from_port>

At the confirmation prompt, press

Y to confirm or N to cancel. When the copy operation

occurs, all previously defined strings on the port being copied to will be replaced.

For more information, see Port Alert Add command on page 57, Port Alert Copy command on
page 57 and Port Alert Delete command on page 58.

To display SNMP configuration information:

Issue a Show Server SNMP command.

Using CCM Appliance Commands

Accessing the CLI

You may access the CLI in three ways: using the Telnet CLI, using the console port or entering the
CLI access character during a session to a serial device. When the CLI is accessed, its prompt
appears (>), indicating you may type a command.

Entering Commands

At the command prompt, type a command and then press Return or Enter. When the key is
pressed, the command line comprises all characters to the left of the cursor. The character at the
cursor and any characters to the right of the cursor are ignored. Table 4.1 lists the line editing
operations for VT100 compatible devices.

43

Table 4.1: Line Editing Operations for VT100 Compatible Devices

Operation Action

Backspace

Left Arrow

Right Arrow

Up Arrow

Down Arrow

Delete

The character immediately before the cursor is erased and all text at and to the right of the
cursor moves one character to the left.

If the cursor is not at the beginning of the line, the cursor moves one character to the left. If
the cursor is at the beginning of the line, no action is taken.

If the cursor is not at the end of the line, the cursor moves one character to the right. If the
cursor is at the end of the line, no action is taken.

The CLI maintains a buffer containing the last 16 typed command lines. If there is a
previous command line, it will be output as the current command line and may be edited. If
there is no previous command line in the command line buffer, the command line is set to
blanks and you may enter a new command.

The next command in the CLI command line buffer is made available for edit. If there is no
next command line, the command line is set to blanks and you may enter a new command.

The character at the cursor position is deleted and all characters to the right of the cursor
position are moved left one character.

44 CCM Installer/User Guide

Table 4.2 lists the line editing operations for ASCII TTY devices. There is no command line buffer
available on an ASCII TTY device.

Table 4.2: Line Editing Operations for ASCII TTY Devices

Operation Action

Backspace Erases the last character typed.

Esc Erases the current command line.

When commands take effect

Each command is completely processed before the next command may be entered. Some
commands prompt for confirmation before they are processed. In these cases, you must confirm or
cancel by entering

Y or N respectively.

If you enter a Server FLASH command or if you change the CCM appliance IP address with a Server
Set command, a reboot is required before the change becomes effective. In these cases, the CCM
database is updated when you enter the command and you are prompted that the change will not take
effect until the CCM appliance reboots. You may choose to reboot at that time, or you may decline.
When the unit reboots, your session and all other sessions on the CCM appliance are terminated.

Understanding Conventions

This section describes the parts of a CCM appliance command and the conventions used in this
document to describe a command’s syntax.

Command syntax

A command may have four types of syntax: positional commands, positional parameters, keyword
parameters and keyword values. The following examples demonstrate the syntax types.

The following Set Port command changes the baud rate and flow control settings for port 2.

> PORT 2 SET BAUD=57600 FLOW=XONXOF

Table 4.3: Command Syntax Types in Example Command

Value Syn tax

PORT Positional command.

2 Positional parameter that indicates the port number for the command.

SET Positional command that indicates port settings are to be changed.

BAUD Keyword parameter, which is always followed by an equal (=) sign.

57600 Keyword value indicating the baud rate value for the BAUD keyword parameter.

FLOW Keyword parameter, which is always followed by an equal (=) sign.

Chapter 4: Using CCM Appliance Commands 45

Table 4.3: Command Syntax Types in Example Command (Continued)

Value Syn tax

XONXOF Keyword value.

Not every command will contain all syntax types. For example, the following command reboots the
CCM appliance.

>SERVER REBOOT

In this case, both SERVER and REBOOT are positional commands.

In most cases, one or more spaces separate positional commands, positional parameters and
keyword parameters.

For most positional commands, positional parameters or keyword parameters, you only need to
enter the first three characters. The exceptions are:

• When you specify a terminal type with the Type parameter in the Server CLI command, you
must enter all characters.

• When you specify an authentication method with the Auth parameter in the Server SSH com­mand, you must enter all characters.

• When you specify control signal monitoring with the Power parameter in the Port Set com­mand, you must enter all characters.

• When you specify the console port in commands such as Port Set and Show Port, you must
enter the capitalized abbreviation

CON.

Port names may contain up to 32 characters, and must be unique; two ports on the same appliance
cannot have the same name. Port names are case sensitive. The name cannot begin with a number
or a space, nor can it contain a double quote (“) or comma (,). The name cannot be Names, All, Set
or Alert (in any case or any shortened form). If the name contains spaces, enclose the name in
double quotes whenever it is used in commands.

With the exception of usernames, passwords, port names and group names, commands are not case
sensitive; they may be entered in uppercase, lowercase or a combination. For example, all of the
following commands are correct.

> PORT 2 SET BAUD=57600 FLOW=XON
> POR 2 SET BAU=57600 FLOW=XON
> por 2 Set Baud=57600 flow=xon
> port 2 set baud=57600 flow=xon

NOTE: Usernames and passwords are case sensitive. These values are stored exactly as you enter them. For
example, the username “Ann” must be entered with an uppercase “A” and all other letters lowercase. The
username “ANN” will not be accepted as the username “Ann.” Usernames and passwords must contain 3-16
alphanumeric characters.

Any syntax errors are displayed, and where applicable, the error is underlined.

46 CCM Installer/User Guide

In the following example, the keyword parameter “baud” is misspelled. Even if more than three
characters are entered, they must all be correct.

> port 2 Set Baux=57600 flow=xon

---­ERR 26 - SET keyword parameter invalid

In the following example, the keyword value “576” is not valid. Numeric keyword values must be
fully specified and may not be shortened to three characters.

> POR 2 SET BAUD=576 FLOW=XON

--­ERR 27 - SET keyword value invalid

In the following example, there are spaces between BAUD, the equal sign and the value 57600.
Spaces are not permitted between keyword parameters and their values.

> POR 2 SET BAUD = 57600 FLOW=XON

-----------­ERR 26 - SET keyword parameter invalid

For commands that display information, if the information spans more than one screen, -More- will
appear on the last line. You may:

Syntax conventions

This manual uses the following command syntax conventions:

• Brackets [ ] surround optional keywords and values.

• Angle brackets < > surround user-supplied positional parameters and keyword parameter values.

• In most cases, choices are separated by a vertical bar |. The description indicates if you may
specify more than one of the choices and how to separate multiple values. The exception is
the Server SSH command. In this case, the vertical bar is specified on the command line
when you wish to enable the “password or key” method (PW|KEY) or the “key or password”
method (KEY|PW).

Connect Command

The Connect command establishes a connection from the console port of the CCM appliance to a
device attached to a serial port on that CCM appliance. To use this command, you must have
previously issued a Server CLI command with the Connect=On parameter. For more information,
see Connecting to Serial Devices on page 17.

Your ability to connect to another port is also affected by session sharing. For more information,
see Session sharing on page 23.

When the connect completes successfully, the message Connected to port x: will be displayed,
followed by the values for port_number,baud,bits_per_character,parity,stop_bits,flow_control.

ENABLE Enables NFS on the appliance.

IP=<nfs_server>

MOUNT=<mount>

FTYPE=LINEAR|DAILY

PROTOCOL=TCP|UDP

DISABLE Disables NFS on the appliance.

IP address of the NFS server, in IP dot notation. The NFS server must support NFSv3
(RFC1813). This parameter is required if NFS is being enabled for the first time.

Mount point (subdirectory location) on the NFS server. This parameter is required if
NFS is being enabled for the first time. The NFS server must be configured to allow
the CCM appliance to access this file system location.

Linear indicates a file will be opened on the NFS server for writing at the end (appended).
Daily indicates a new file will be created on the NFS server every midnight.
For either file type, if the file being opened does not already exist, it will be created. If
the file already exists, it will be opened for writing at the end (appended).
Default = Linear

Specifies the network protocol to be used between the CCM appliance and the
NFS server.
Default = TCP

Examples

The following command enables the use of the NFS on the CCM appliance. The NFS server is
located at IP address 192.168.52.50, and files will be created under the subdirectory c/ccm_history
every midnight.

the port (and a unique daily port file if the file type is daily). Substitution strings may
be used; see Table 3.7 on page 37.
Default = ““ (P%#.hst if file type is linear, P%#_%F.hst if file type is daily)

Number of bytes that will be buffered on the CCM appliance before being written to
the NFS server file. This threshold is used with the Time value to determine when
accumulated data will be written. Valid values are 0-3584 bytes.
Default = 0 bytes

Maximum number of seconds that will be allowed to elapse before buffered data will
be written to the NFS server file. This threshold is used with the Size value to
determine when accumulated data will be written. Valid values are 0-65536 seconds.
Default = 1 second

Examples

The following command enables NFS on port 3, using the default filename specification, and
setting a size threshold of 20 bytes and a time threshold of zero. With this configuration, data will
be buffered according to the non-zero threshold value, 20 bytes, then it will be written to the NFS
history file. The history file will be named P03.hst if the file type is linear, or P03_<4-digit year>­<2-digit_month>-<2-digit_day> if the file type is daily.

port 3 nfs ena size=20 time=0 file=

The following command enables NFS on port 7, using a substitution string within the filename
specification, and setting zero thresholds for both size and time. (This configuration will not be
acceptable if the file type is daily, because the file specification does not include a date substitution
string that would make each daily file uniquely named.) Assuming the file type is linear, data will
be written to the NFS server file named ccm_1_P07 as soon as it is available, because both
thresholds are zero.

port 7 nfs ena size=0 time=0 file=ccm_1_%#

Port Set command

The Port Set command changes serial port settings in the CCM configuration database. At least one
keyword parameter and value must be specified. Some changes become effective upon the next
connection to the port.

There may be a difference between the display for a Show User command (without a username)
and Show User <current_username>. If you do not specify a username, the command displays the
current user credentials; with a username, the information comes from the database.

For example, assume username Admin is logged in with Access=PALL. Then, a User Set Admin
Access=–PALL command is issued and the database is modified. A Show User command (without
a username) will display the access as PALL, while a Show User Admin command will display the
new access without PALL.

A Show User All command display includes the information in Table 5.38.

Indicates if the user may connect to ports BY GROUP or BY PORT.

If there is any group defined for any ports (which can be determined with a Show

Port Groups command), each user may connect BY GROUP, unless a user’s access

rights include PALL, in which case, a user may connect BY PORT.

If a user is assigned an empty group (with no ports in it) or no groups at all, that user

may lose access to any port once there is a group defined for any port.
