1. Switch Management

1.1.Configuration Options

For advanced management capability, the onboard management agent provides a

menu-driven system configuration program. This program can be accessed by a direct

or modem connection to the serial port on the rear panel (out-of-band), or by a Telnet

connection over the network (in-band).

The management agent is based on SNMP (Simple Network Management Protocol).

This SNMP agent permits the switch to be managed from any PC in the network using

in-band management software.

The management agent also includes an embedded HTTP Web agent. This Web agent

can be accessed using a standard Web browser from any computer attached to the

network.

The system configuration program and the SNMP agent support management functions

such as:

• Enable / disable any port.

• Set the communication mode for any port.

• Configure SNMP parameters.

• Add ports to network VLANs.

• Configure IP routing and multicast VLANs.

• Display system information or statistics.

• Configure the switch to join a Spanning Tree.

• Download system firmware.

1.2.Required Connections

1.2.1.Console Port (Out-of-Band) Connections

Attach a VT100 compatible terminal or a PC running a terminal emulation program to

the serial port on the switch’s rear panel. Use the null-modem cable provided with this

package, or use a null-modem connection that complies with the wiring assignments

shown in Appendix B of this guide.

When attaching to a PC, set terminal emulation type to VT100, specify the port used by

your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit, no

parity, and 19200 bps (for initial configuration). Also be sure to set flow control to “none.”

(Refer to “Configuring the Serial Port” on chapter 2 for a complete description of

configuration options.)

Note:

If the default settings for the management agent’s serial port have been modified

and you are having difficulty making a console connection, you can display or

modify the current settings using a Web browser as described under “Configuring

the Serial Port” on chapter 3.

1.2.2.Remote Management Via the Console Port

1.2.2.1.Configuring the Switch Site

Connect the switch’s DB9 serial port to the modem’s serial port uses standard cabling.

For most modems which use a 25-pin port, you will have to provide an RS-232 cable

with a 9-pin connector on one end and a 25-pin connector on the other end. Set the

modem at the switch’s site to force auto-answer mode. The following is a sample

initialization string: “ATQ1S0=1&D0&K0&W” as defined below:

Q1 : Inhibit result codes to DTE

S0=1 : Auto answer on first ring

D0 : Don’t care DTR

K0 : Disables DTE / DCE flow control

W : Write command to modem memory

1.2.2.2.Configuring the Remote Site

At the remote site, connect the PC’s COM port (COM 1~4) to the modem’s serial port.

Set terminal emulation type to VT100, specify the port used by your PC (i.e., COM 1~4),

and then set communications to 8 data bits, 1 stop bit, no parity, 19200 bps, and no flow

control.

1.2.3.In-Band Connections

Prior to accessing the switch’s onboard agent via a network connection, you must first

configure it with a valid IP address, subnet mask, and default gateway (for Layer 2

mode) using an out-of-band connection or the BOOTP protocol.

After configuring the switch’s IP parameters, you can access the onboard configuration

program from anywhere within the attached network. The onboard configuration

program can be accessed using Telnet from any computer attached to the network. The

switch can also be managed by any computer using a Web browser (Internet Explorer

4.0 or above, or Netscape Navigator 4.0 or above), or from a network computer using

network management software.

Notes:

1. By default BOOTP is disabled. To enable BOOTP, see “IP Configuration

(Layer 2 Mode)” on chapter 2.

2. Each VLAN group can be assigned its own IP interface address (chapter 2

“IP Configuration (Layer 2 Mode)”). Therefore, if the port connected to the

management station has joined several VLANs, you can manage the switch

via any of these IP addresses.

3. This switch supports four concurrent Telnet sessions.

4. The onboard program only provides access to basic configuration functions.

To access the full range of SNMP management functions, you must use

SNMP- based network management software.

2. Console Interface

2.1.Log-in Screen

Once a direct connection to the serial port or a Telnet connection is established, the log-in screen for the onboard configuration program appears as shown below.

Intelligent Switch V1.00 10-19-2001 (c) Copyright communications Corp. User Name: Password :

1. For Management Model, it will display “Management Switch”.

If this is your first time to log into the configuration program, then the default user names

are “admin” and “guest,” with no password. The administrator has Read / Write access

to all configuration parameters and statistics, while the guest has Read Only access to

the management program.

You should define a new administrator password, record it and put it in a safe place.

Select User Configuration from the Management Setup Menu and enter a new

password for the administrator. Note that passwords can consist of up to 15

alphanumeric characters and are not case sensitive.

Note:

You are allowed three attempts to enter the correct password; on the third failed

attempt the current connection is terminated.

After you enter the user name and password, you will have access to the system

configuration program illustrated by the following menu map:

<Apply> <OK> <Cancel> IP address of this system for Ethernet. | READ/WRITE Use <TAB> or arrow keys to move, other keys to make changes.

Parameter Description

Interface Type Indicates IP over Ethernet. IP Address IP address of the switch you are managing. The system supports

SNMP over UDP / IP transport protocol. In this environment, all systems on the Internet such as network interconnection devices and any PC accessing the agent module (or running network management software) must have an IP address. Valid IP addresses consist of four numbers, 0 to 255, separated by periods. Anything outside this format will not be accepted by the configuration program.

Subnet Mask Subnet mask of the switch. This mask identifies the host address

bits used for routing to specific subnets.

Default Gateway Gateway used to pass trap messages from the system’s agent to

the management station. Note that the gateway must be defined (when operating at Layer 2) if the management station is located in a different IP segment.

IP State Specifies whether IP functionality is enabled via manual

configuration, or set by Boot Protocol (BOOTP). Options include:

USER-CONFIG IP functionality is enabled based on the default

or user specified IP Configuration. (This is the default setting.)

BOOTP Get IP IP is enabled but will not function until a BOOTP

reply has been received. BOOTP requests will be broadcast periodically by the switch in an effort to learn its IP address. (BOOTP values can include the IP address, default gateway, and subnet mask.)

Mgt. Access Allows management access of the switch from all VLANs or only

from a specified VLAN. If you select “Mgmt VLAN,” then select Apply to display the VLAN ID field, select the required VLAN, and then select Apply or OK to save your changes.

2.4.1.2.IP Connectivity Test (Ping)

2.4.3.Assigning SNMP Parameters

Use the SNMP Configuration screen to display and modify parameters for the Simple

Network Management Protocol (SNMP). The switch includes an onboard SNMP agent

which monitors the status of its hardware, as well as the traffic passing through its ports.

A computer attached to the network, called a Network Management Station (NMS), can

be used to access this information. Access rights to the onboard agent are controlled by

community strings. To communicate with the switch, the NMS must first submit a valid

community string for authentication. The options for configuring community strings and

related trap functions are described in the following sections.

SNMP Configuration ==================

Send Authentication Fail Traps : ENABLED

SNMP Communities ...

IP Trap Manager ...

<OK> Send a trap or not when SNMP authentication fails. | READ/SELECT Use <TAB> or arrow keys to move, <Space> to scroll options.

Parameter Description

Send Authentication Fail Traps

Issue a trap message to specified IP trap managers whenever authentication of an SNMP request fails. (The default is enabled.)

SNMP Communities Assigns SNMP access based on specified strings.

IP Trap Managers Specifies management stations that will receive authentication

failure messages or other trap messages from the switch.

2.4.3.1.Configuring Community Names

The following figure and table describe how to configure the community strings

authorized for management access. Up to 5 community names may be entered.
