Introduction

The 1Gb Intelligent L2 Switch provides two switch modes: The conventional L2 switch mode, and SmartPanel
mode. The switch can store up to two different software image, called image1 and image2. Normally, the
conventional L2 switch software image is stored in image1, and the SmartPanel software is stored in image2. You
can select which software image (image1 or image2) you want to run in switch memory. By default, the switch
software is loaded from image1. To run the SmartPanel software, you need to change a software image to image2
and reboot the switch. See additional references for configuration to select a software image.

This guide explains how to configure the switch in running the SmartPanel software. The SmartPanel pr ovides a
simple Ethernet interface option for connecting to the network infrastructure. The number and type of configuration
options on the SmartPanel are restricted to reduce the initial setup complexit y and to minimize the impact on
upstream networking devices.

Management Network

The 1Gb Intelligent L2 Switch is a Switch Module within the Blade Enclosure. The Blade Enclosur e includes an
Enclosure Manager Card which manages the modules and CPU Blades in the enclosure.

The 1Gb Intelligent L2 Switch communicates with the Enclosure Manager Card through its internal management
port (port 19). The factory default settings permit management and control access to the switch through the 10/100
Mbps Ethernet port on the Blade Enclosure, or the built-in console port.

The switch management network has the following characteristics:

• Port 19 — Management port 19 has the following configuration:

• Flow control: both

• Auto-negotiation

• Untagged

• Port VLAN ID (PVID): 4095

• VLAN 4095 — Management VLAN 4095 isolates management traffic within the switch. VLAN 4095 contains

only one member port (port 19). No other ports can be members of VLAN 4095.

• Interface 256 — Management interface 256 is associated with VLAN 4095. No other interfaces can be
associated with VLAN 4095. The IP address of the management interface is assigned through Dynamic Host
Control Protocol (DHCP).

• Gateway 4 — This gateway is the default gateway for the management interface.

Connecting to the switch

You can access the command line interface in one of the following ways:

• Using a console connection via the console port

• Using a Telnet connection over the network

• Using a Secure Shell (SSH) connection to securely log in over a network

• Using a HTTP connection over the network

Establishing a console connection

To establish a console connection with the switch, you need:

• A null modem cable with a female DB-9 connector (See the User’s Guide for more information.)

• An ASCII terminal or a computer running terminal emulation software set to the parameters shown in the table

below

Table 2 Console configuration parameters

Parameter Value
Baud Rate 9600
Data Bits 8

Parity None
Stop Bits 1
Flow Control None

To establish a console connection with the switch:

1. Connect the terminal to the console port using the null modem cable.

2. Power on the terminal.

3. Press the Enter key a few times on the terminal to establish the connection.

4. You will be required to enter a password for access to the switch. (For more information, see the “Accessing
the switch” section later in this chapter.)

SmartPanel 6

Setting an IP address

To access the switch via a Telnet, an SSH connection, or an HTTP connection, you need to have an Internet
Protocol (IP) address set for the switch. You can assign the IP address only to the management interface (interface

256), associated with port 19. The management interface requests its IP address from a Dynamic Host Control

Protocol (DHCP) server on the Enclosure Manager Card. See the User’s Guide of the Enclosure Manager Card for
configuration to assign the IP address to the switch modules.

NOTE: You can assign the IP address only on the management port 19.

Establishing a Telnet connection

A Telnet connection offers the convenience of accessing the switch from any workstation connected to the network.
Telnet provides the same options for user, operator, and administrator access as those available through the
console port. By default, Telnet is enabled on the switch. The switch supports four concurrent Telnet connections.

Once the IP parameters are configured, you can access the CLI using a Telnet connection. To establish a Telnet
connection with the switch, run the Telnet program on the workstation and enter the telnet command, followed by
the switch IP address:

telnet <1Gb Intelligent L2 Switch IP address>

You will then be prompted to enter a password. The password entered determines the access level: administrator,
operator, or user. See the “Accessing the switch” section later in this chapter for description of default passwords.

Establishing an SSH connection

Although a remote network administrator can manage the configuration of a switch via Telnet, this method does not
provide a secure connection. The Secure Shell (SSH) protocol enables you to securely lo g into the switch over the
network.

As a secure alternative to using Telnet to manage switch configuration, SSH ensures that all data sent over the
network is encrypted and secure. In order to use SSH, you must first configure it on the switch. See the “Secure
Shell Server configuration” section in the “Configuration Menu” chapter for information on how to configure SSH.

Establishing an HTTP connection

By default, HTTP is enabled on the switch. You can configure the switch using the Web browser. For more
information, see the “Browser-based interface” chapter.

Accessing the switch

To enable better switch management and user accountability, the switch provides different levels or classes of user
access. Levels of access to the CLI and Web management functions and screens increase as needed to perform
various switch management tasks. The three levels of access are:

• User—User interaction with the switch is completely passive; nothing can be changed on the switch. Users
may display information that has no security or privacy implications, such as switch statistics and current
operational state information.

• Operator—Operators can only effect temporary changes on the switch. These changes will be lost when the
switch is rebooted/reset. Operators have access to the switch management features used for daily switch
operations. Because any changes an operator makes are undone by a reset of the switch, operators cannot
severely impact switch operation, but do have access to the Maintenance menu.

• Administrator—Only administrators can make permanent changes to the switch configuration, changes that
are persistent across a reboot/reset of the switch. Administrators can access switch functions to configure and
troubleshoot problems on the switch. Because administrators can also make temporary (operator-level)
changes as well, they must be aware of the interactions between temporary and permanent changes.

Access to switch functions is controlled through the use of unique usernames and passwords. Once you are
connected to the switch via the local console, Telnet, or SSH, you are prompted to enter a password. The
password entered determines the access level. The default user names/password for each access level is listed in
the following table. Once you are connected to the switch via HTTP, you are prompted to enter a user account and
password.

NOTE: It is recommended that you change default switch passwords after initia l configuration and as
regularly as required under your network security policies. For more information, see the “Setting passwords”
section in the “First-time configuration” chapter.

Browser-based interface

Introduction

This chapter explains how to access the switch browser-based interface (BBI) for the SmartPanel and configure the
switch.

Requirements

To use the browser-based interface, you need the following:

• PC or workstation with network access to the switch

• Frame-capable Web-browser software, such as the following:

• Netscape Navigator 4.7x or higher

• Internet Explorer 6.0x or higher

• JavaScript enabled in your Web browser

Web browser setup

Most modern Web browsers work with frames and JavaScript by default, and require no addition al set up. Ho wever,
you should check your Web browser’s features and configuration to be sure frames and JavaScript are enabled.

NOTE: JavaScript is not the same as Java™. Be sure that JavaScript is enabled in your Web browser.

Starting the BBI

When the switch and browser setup is complete, follow these steps to launch the BBI:

1. Start your Web browser.

2. Enter the switch IP interface address in the Web browser Uniform Resource Locator (URL) field.
For example, if the switch IP interface has a network IP address of 192.168.3.70. Using Internet Explorer, you

could enter the following (for secure BBI access, use https://).

If you do not use the default TCP port number (80) for BBI access, you can include the port number when you
enter the IP address:

Browser-based interface 9

If the switch IP interface address has a name on your local domain name server, you can enter the name
instead. Using Internet Explorer, you can enter the following:

3. Log in to the switch.
If your switch and browser are properly configured, you will be asked to enter a password.

Enter the account name and password for the switch.

4. Allow the BBI Dashboard page to load.
When the proper account name and password combination is entered, the BBI Port Group Mapping page is

displayed in the browser viewing area.

NOTE: There may be a slight delay while the Port Group Mapping page is initial izing. You should not stop
the browser while loading is in progress.

Port Group Mapping

SmartPanel ports can be combined into Port Groups. Up to five Port Groups are available in the SmartPanel. A
Spare Ports Group is available for unused ports.

VLANs and Link Aggregation Groups (trunks) are configured automatically for each Port Group. No network loops
are allowed in the configuration. All external ports in the Port Group form a trunk group (static trunk or Link
Aggregation Group).

Port Group Characteristics

SmartPanel Port Groups must have the following characteristics.

• Each Port Group must contain at least one external port (20-24) and one internal server blade port (1-16).

• All external ports in a Port Group must have the same configuration.

• Each port in the Port Group is a member of a unique, untagged VLAN.

• Tagged VLANs (1-4094) can be assigned to each Port Group. Tagged VLANs cannot be configured across

multiple Port Groups.

• All external ports in the Port Group form a trunk group.

NOTE: Cross-connect ports (17-18) are not available in the SmartPanel.

Port Group configuration

On the BBI, choose Port Group Mapping to select the Port Group for each of the external ports and server blade
ports. Click Apply to make the changes active. Click Save to write the configuration to flash memory.

Browser-based interface 13

In this example, Port 1-4, 20-21 are assigned to Group1, and Port 5-8, 22-23 are assigned to Group2. The others
are assigned to Spare Ports Group.

• none: No flow control

Browser-based interface 15

VLAN

Virtual LANs (VLANs) are commonly used to split up groups of network users into manageable broadcast domains,
to create logical segmentation of workgroups, and to enforce security policies among logic al segments. This switch
supports up to 1,000 VLANs per switch. Even though the maximum number of VLANs supported at any given time
is 1,000, each can be identified with any number between 1 and 4095. VLAN 4095 is used by the management
network, which includes the management port 19. VLAN 4095 configuration cannot be modified.

PVID

Each Port Group has a configurable default VLAN number, known as its PVID (Port VLAN ID). All ports are set as
untagged members of PVID. By default, all ports except port 19 are configured as Group1. The PVID of Group1 is 1.

The unique value of PVID is assigned to the Port Group, which contains at least one external port and one internal
server blade port. For the configuration, see the “Port VLAN ID configuration” section later in this chapter.

NOTE: Spare Ports Group for unused ports is assigned a PVID.

802.1Q VLAN Tagging

802.1Q VLAN tagging provides standards-based VLAN support for Ethernet systems. This standard permits

multiple VLANs to be transmitted over a single Ethernet connection.
Tagging places the VLAN identifier in the frame header of a packet, allowing each port to belo ng to multiple VLANs.

For the configuration to add the VLAN ID to the Port Group, see the “Non-Default Virtual LANs” section later in this
chapter.

NOTE: The SmartPanel does not permit configuration of tagged VLANs across multiple Ports Groups.

Port VLAN ID configuration

Assign at lease one external port and one internal blade server port to the Port Group to use it and assign a uniqu e
value of PVID. On the BBI, choose System settings > Uplink/Group to change the PVID. Edit the value of the
following Port VLAN ID. The value of unused Port Group is 0.

Browser-based interface 16

Non-Default Virtual LANs

On the BBI, choose Non-Default Virtual LANs to create VLANs and assign them to Port Groups. The non-default
VLAN ID is placed in the frame header of a packet in forwatding from the port.

The following describes the steps to add VLAN ID.

1. Click Add VLAN to configure a new VLAN.

2. Enter a VLAN number and click OK.

The following is displayed.

Trunking

Trunk groups provide super-bandwidth, multi-link connections between SmartPane l or other trunk-capable devices.
A trunk group is a group of ports that act together, combining their bandwidth to create a single, larger virtual link.

SmartPanel trunk groups are static link aggregation groups that are compatible with Cisco’s EtherChan nel
technology.

The SmartPanel is statically configured to place each Port Group into a separate trunk group.

NOTE: Because all ports in a Port Group belong to the same trunk group, individual external ports cannot be
used as a regular 802.3 link. Do not plug a workstation directly into one of the SmartPanel’s external ports,
unless that is the only device plugged into the ports.

When using port trunk groups between the SmartPanel and a switch, you can cr eate a virtual link, operating at up
to 5 Gigabits per second, depending on how many physical ports are combined.

Statistical Load Distribution

Network traffic is statistically distributed between ports in a trunk group. The SmartPanel uses the source and
destination IP address information present in each transmitted IP frame to determine load distribution. If the frame
is not an IP frame, then Layer 2 MAC addresses are used.

Each packet’s particular combination of source and destination addresses results in selecting one li ne in the trunk
group for data transmission. If there are enough devices feeding the trunk lines, then traffic distribution becomes
relatively even.

Built-In Fault Tolerance

Since trunk groups are comprised of multiple physical links, each trunk group is inhere ntl y fault tolerant. As long as
one connection is available, the trunk remains active.

Statistical load balancing is maintained whenever a port in a trunk group is lost or returned to service.

Trunk group configuration rules

The trunking feature operates according to specific configuration rules. When working with trunks, consider the
following rules that determine how a trunk group reacts in any network topology.

• All trunks must originate from one device, and lead to one destination device.

• Trunking from third-party devices must comply with Cisco® EtherChannel® technology.

• All external ports in a Port Group must have the same configuration.

• Only external ports in a Port Group are trunked. For Port Group configuration, see the “Port Group

configuration”.

Link Aggregation Control Protocol

Link Aggregation Control Protocol (LACP) is an IEEE 802.3ad standard for grouping seve ral physical ports into one
logical port (known as a dynamic trunk group or Link Aggregation Group) with any device that supports the
standard. Please refer to IEEE 802.3ad-2002 for a full description of the standard.

The 802.3ad standard allows standard Ethernet links to form a singl e Layer 2 link using the Link Aggregation
Control Protocol (LACP). Link aggregation is a method of grouping p hysical link segments of the same media type
and speed in full duplex, and treating them as if they were part of a single, logical link segment. If a link in a LACP
trunk group fails, traffic is reassigned dynamically to the remaining link/s of the dynamic trunk group.

Browser-based interface 22

Trunk Group configuration

On the BBI, choose System Settings > Uplink/Group to enable or disable the Link Aggregation Control Protocol.
When enabled, the external ports are configured as a LACP trunk group. When disabled, they are configured as a
static trunk group. The default is disabled.

Failover

The primary application for Failover is to support Network Adapter Teaming. With Network Adapter Teaming, the
NICs on each server all share the same IP address, and are configured into a team. One NIC is the primary link,
and the other is a standby link.

Failover is enabled by default. You can enable or disable Failover on a Port Group. When enabled, F ailover works
as follows.

• If some (or all) of the links fail in the failover trigger, the SmartPanel disables all internal ports of the Port
Group. When the internal ports are disabled, it causes the NIC team on the affected server blade to failover
from the primary to the backup NIC. This process is called a failover event.

• When the appropriate links return to service, the SmartPanel enables the internal ports of the Port Group.
This causes the NIC team on the affected server blades to fail back to the primary SmartPanel (unless Auto­Fallback is disabled on the NIC team). The backup processes traffic until the primary’s internal l inks come up,
which takes up to five seconds.

The failover limit lets you specify the minimum number of operational links required within the failover trigger before
the trigger initiates a failover event. For example, if the limit is four, a failover event occurs when the number of
operational links in the trigger is four or fewer. When you set the limit to all, the SmartPanel triggers a failover event
only when no links in the trigger are operational. The default is all.

Browser-based interface 23

Failover configuration

On the BBI, choose System Settings > Uplink/Group to configure the Switch Failover and Number of Links to
Trigger Failover.

IGMP Snooping

IGMP Snooping allows the SmartPanel to forward multicast traffic only to those ports that request it. IGMP
Snooping prevents multicast traffic from being flooded to all ports. The SmartPanel learns which server hosts are
interested in receiving multicast traffic, and forwards it only to ports connected to those servers.

On the BBI, choose System Settings > IGMP Snooping to enable IGMP Snooping. The default is disabled.

Command Line Interface

Introduction

The CLI is used for viewing switch information and statistics. In addition, the administrator can use the CLI for
performing all levels of switch configuration.

To make the CLI easy to use, the various commands have been logically grouped into a series of menus and
submenus. Each menu displays a list of commands and/or submenus that are available, along with a summary of
what each command will do. Below each menu is a prompt where you can enter any comm and appropriate to the
current menu.

This chapter describes the Main Menu commands, and provides a list of commands and shortcuts that are
commonly available from all the menus within the CLI.

Main Menu

The Main Menu displays after a successful connection and login. The follo wing ta ble shows the Main Menu for the
administrator login. Some features are not available under the user login.

[Main Menu]
info - Information Menu
stats - Statistics Menu
cfg - Configuration Menu
oper - Operations Command Menu
boot - Boot Options Menu
maint - Maintenance Menu
diff - Show pending config changes [global command]
apply - Apply pending config changes [global command]
save - Save updated config to FLASH [global command]
revert - Revert pending or applied changes [global command]

exit - Exit [global command, always available]

Menu summary

The Main Menu displays the following submenus:

• Information Menu
The Information Menu provides submenus for displaying information about the current status of the switch.

• Statistics Menu
This menu provides submenus for displaying switch performance statistics.

• Configuration Menu
This menu is available only from an administrator login. It includes subme nus for configuring every aspect of

the switch. Changes to configuration are not active until explicitly applied. Changes can be saved to non­volatile memory (NVRAM).

• Operations Command Menu
Operations-level commands are used for making immediate and temporary changes to switch configurati on.

This menu is used for bringing ports temporarily in and out of service. This menu is available only from an
administrator and operator login.

• Boot Options Menu
The Boot Options Menu is available only from an administrator login. This menu is used for upgrading switch

software, selecting configuration blocks, and for resetting the switch when necessary. This menu is also used
to set the switch back to factory settings.

• Maintenance Menu
This menu is used for debugging purposes, enabling you to generate a tec hnical support dump of the critical

state information in the switch, and to clear entries in the Forwarding Database and the Address Resolution
Protocol (ARP). This menu is available only from an administrator and operator login.

Command Line Interface 27

Global commands

Some basic commands are recognized throughout the menu hierarchy. These commands are useful for obtaining
online Help, navigating through menus, and for applying and saving configuration changes.

Command Line Interface 29

Command line interface shortcuts

The following shortcuts allow you to enter commands quickly and easily.

Command stacking

As a shortcut, you can type multiple commands on a single line, separated by forward slashes (/). You can connect
as many commands as required to access the menu option that you want.

For example, the keyboard shortcut to access the Simple Network Management Protocol (SNMP) Configuration
Menu from the Main# prompt is:

Main# cfg/sys/ssnmp/name

Command abbreviation

Most commands can be abbreviated by entering the first characters that distinguish the command from the others
in the same menu or submenu.

For example, the command shown above could also be ent ered as:

Main# c/sys/ssn/n

Tab completion

By entering the first letter of a command at any menu prompt and pressing the Tab key, the CLI will display all
commands or options in that menu that begin with that letter. Entering additional letters will further refine the list of
commands or options displayed.

If only one command fits the input text when the Tab key is pressed, that command will be supplied on the
command line, waiting to be entered. If the Tab key is pressed without any input on the command line, the currently
active menu displays.

The User-based Security Model (USM) in SNMPv3 provides security services such as authentication and privac y of
messages. This security model makes use of a defined set of user identities displayed in the USM user table. The
USM user table contains information like:

• the user name

• a security name in the form of a string whose format is independent of the Security Model

• an authentication protocol, which is an indication that the messages sent on behalf of the user can be

authenticated

• the privacy protocol

the read or write type of operation or notification into a MIB view.
The View-based Access Control Model defines a set of services that an application can use for checking access

rights of a group. This group’s access rights are determined by a read-view, a write-view, and a notify-view. The
read-view represents the set of object instances authorized for the group while reading the objects. The write-view
represents the set of object instances authorized for the group when writing objects. The notify-view represents the
set of object instances authorized for the group when sending a notification.

An address that is in the forwarding (FWD) state indicates that the switch has learned it. When in the trunking
(TRK) state, the Trnk field displays the trunk group number. If the state for the port is listed as unknown (UNK), the
MAC address has not yet been learned by the switch, but has only been seen as a destinatio n address. When an
address is in the unknown state, no outbound port is indicated.

A frame received on the interface corresponding to this port is counted by
this object, if and only if, it is for a protocol being processed by the local
bridging function, including bridge management frames.

dot1PortOutFrames The number of frames that have been transmitted by this port to its

segment.
A frame transmitted on the interface corresponding to this port is counted
by this object, if and only if, it is for a protocol being processed by the local

the forwarding process.

dot1TpLearnedEntryDiscards The total number of Forwarding Database entries, which have been or

would have been learned, but have been discarded due to a lack of space
to store them in the Forwarding Database.
If this counter is increasing, it indicates that the Forwarding Database is
regularly becoming full (a condition which has adverse performance effects
on the sub network).
If this counter has a significant value but is not presently increasing, it
indicates that the problem has been occurring but is not persistent.

Configuration Menu

Introduction

The Configuration Menu is only available from an administrator login. It includes submenus for configuring every
aspect of the switch. Changes to configuration are not active until explicitly applied. Changes can be saved to non­volatile memory (NVRAM).

Menu information

Command: /cfg

[Configuration Menu]
sys - System-wide Parameter Menu
port - Port Menu
spgroup - Spare Ports Group Menu
group - Group Menu
dump - Dump current configuration to script file
ptcfg - Backup current configuration to FTP/TFTP server

The following table describes the Configuration Menu options.

Table 57 Configuration Menu options

Viewing, applying, reverting, and saving changes

gtcfg - Restore current configuration from FTP/TFTP server

Command Usage

sys Displays the System Menu.
port <port number> Displays the Port Menu.
spgroup Displays the Spare Ports Group Menu.
group <group number> Displays the Group Menu.
dump Dumps current configuration to a script file.
ptcfg <server IP address> <filename on
host>
gtcfg <server IP address> <filename on
host>

Backs up current configuration to TFTP or FTP server.

Restores current configuration from TFTP or FTP server.

As you use the configuration menus to set switch parameters, the changes you make do not take effect
immediately. All changes are considered pending until you e xp licitly apply them. Also, any changes are lost the
next time the switch boots unless the changes are explicitly saved.

While configuration changes are in the pending state, you can:

• View the pending changes

• Apply the pending changes

• Revert to restore configuration parameters set with the last apply command

• Save the changes to flash memory

Command Line Interface 60

Viewing pending changes

You can view all pending configuration changes by entering diff at any CLI prompt:

# diff

You can view all pending configuration changes that have been applied but not saved to flash memory by entering

diff flash at any CLI prompt:

# diff flash

Applying pending changes

To make your configuration changes active, you must apply them. To apply configur ation changes, enter the
following command at any prompt:

# apply

NOTE: All configuration changes take effect immediately when applied.

Reverting changes

The revert command removes configuration changes that have been made, but not applied. Enter revert apply
to remove all changes that have not been saved:

# revert

Saving the configuration

In addition to applying the configuration changes, you can save them to flash memory on the switch.
IMPORTANT: If you do not save the changes, they will be lost the next time the system is rebooted.

To save the new configuration, enter the following command at any prompt:

# save

When you save configuration changes, the changes are saved to the active configuration block. T he configuration
being replaced by the save is first copied to the backup configuration block. If you do not want the previous
configuration block copied to the backup configuration block, enter the following i nstead:

# save n

You can decide which configuration you want to run the next time you reset the switch. Your options include:

• The active configuration block

• The backup configuration block

• Factory default configuration block

You can view all pending configuration changes that have been applied but not saved to flash memory using the
diff flash command. It is a global command that can be executed from any prompt.

For instructions on selecting the configuration to run at the next system reset, see the “Selecting a configuration
block” section in the “Boot Options Menu” chapter.

more secure than the TACACS encryption protocol. TACACS+ is described in RFC 1492.

TACACS+ protocol is more reliable than RADIUS, as TACACS+ uses the Transmission Control Protocol (TCP)
whereas RADIUS uses the User Datagram Protocol (UDP). Also, RADIUS combines authentication and
authorization in a user profile, whereas TACACS+ separates the two operations.

TACACS+ offers the following advantages over RADIUS as the authentication device:

• TACACS+ is TCP-based, so it facilitates connection-oriented traffic.

• It supports full-packet encryption, as opposed to password-only in authentication requests.

• It supports decoupled authentication, authorization, and accounting.

The following table describes the TACACS+ Server Configuration Menu options.

Command Line Interface 66

IMPORTANT: If TACACS+ is enabled, you must login using TACACS+ authentication when connecting via
the console or Telnet/SSH/HTTP/HTTPS. Backdoor for console is always enabled, so you can connect using
notacacs and the administrator password even if the backdoor (bckdoor) or secure backdoor (secbd) are
disabled.

If backdoor is enabled (bckdoor ena), type in notacacs as a backdoor to bypass TACACS+ checking, and
use the administrator password to log into the switch. The switch allows this even if TACACS+ servers are
available.

If secure backdoor is enabled (secbd ena), type in notacacs as a backdoor to bypass TACACS+ checking,
and use the administrator password to log into the switch. The switch allows this only if TACACS+ servers are
not available.

The switch software supports SNMP-based network management. In SNMP model of network management, a
management station (client/manager) accesses a set of variables known as MIBs (Management Information Base)
provided by the managed device (agent). If you are running an SNMP network management station on your
network, you can manage the switch using the following standard SNMP MIBs:

• MIB II (RFC 1213)

• Ethernet MIB (RFC 1643)

• Bridge MIB (RFC 1493)

An SNMP agent is a software process on the managed device that listens on UDP port 161 for SNMP messages.
Each SNMP message sent to the agent contains a list of management objects to retrieve or to modify.

• SNMP parameters that can be modified include:

• System name

• System location

• System contact

• Use of the SNMP system authentication trap function

• Read community string

• Write community string

The following table describes the System SNMP Configuration Menu options.

Boot Options Menu

Introduction

You must be logged in to the switch as the administrator to use the Boot Options Menu.
The Boot Options Menu provides options for:

• Selecting a switch software image to be used when the switch is next reset.

• Selecting a configuration block to be used when the switch is next reset.

• Downloading or uploading a new software image to the switch via FTP or TFT P.

Menu information

Command: /boot

[Boot Options Menu]
image - Select software image to use on next boot

conf - Select config block to use on next boot
gtimg - Download new software image via FTP/TFTP
ptimg - Upload selected software image via FTP/TFTP
reset - Reset switch
cur - Display current boot options

Each of the Boot Options Menu commands is discussed in greater detail in the following sections.

Updating the switch software image

The switch software image is the executable code running on the switch. A version of the image ships with the
switch, and comes pre-installed on the device. As new versions of the image are released, you can upgrade the
software running on the switch.

Upgrading the software image on the switch requires the following:

• Loading the new image onto a FTP or TFTP server on your network

• Downloading the new image from the FTP or TFTP server to the switch

• Selecting the new software image to be loaded into switch memory the next time the switch is reset

Downloading new software to the switch

The switch can store up to two different software images, called image1 and image2, as well as boot software,
called boot. When you download new software, you must specify where it should b e placed: either into image1,
image2, or boot.

By default, the software for conventional Layer2 switch mode is stored in image1 and the software for SmartPanel
mode is stored in image2.

To download new software to the switch, you will need the following:

• The image or boot software loaded on a FTP or TFTP server on your network

• The IP address of the FTP or TFTP server

• The name of the new software image or boot file

When the above requirements are met, use the following procedure to download the new software to the switch.

1. At the Boot Options# prompt, enter:

Boot Options# gtimg

2. Enter the name of the switch software to be replaced:

Enter name of switch software image to be replaced
["image1"/"image2"/"boot"]: <image>

3. Enter the IP address of the FTP or TFTP server:

Enter IP address of FTP/TFTP server: <IP address>

4. Enter the name of the new software file on the server:

Enter name of file on FTP/TFTP server: <filename>

Command Line Interface 82

The exact form of the name will vary by FTP/TFTP server. However, the file location is normally relative to the
FTP/TFTP directory.

5. Enter the username, if you are using a FTP server:

Enter username for FTP server or hit return for TFTP server: <userID>

6. Enter the password for the FTP server (if prompted):

Enter password for username on FTP server: <password>

7. The system prompts you to confirm your request.
You should next select a software image to run, as described in the “Selecting a Soft Image to Run” section.

8. If you are loading an image from which you are not currently booted, the system prompts you to change the
image.

image2 currently contains Software Version 1.0.0
that was downloaded at 15:46:36 Wed Apr 23, 2006.
New download will replace image2 with file "1.0.1_OS.img"
from TFTP server 192.168.2.4.

Do you want to change that to the new image2? [y/n] y
Next boot will use new software image2.

Selecting a software image to run

You can select which software image (image1 or image2) you want to run in switch memory for the next reboot.

1. At the Boot Options# prompt, enter:

Boot Options# image

2. Enter the name of the image you want the switch to use upon the next boot. The system informs you of which
image is currently set to be loaded at the next reset, and prompts you to enter a new choice:

Currently set to use switch software "image1" on next reset.

Specify new image to use on next reset ["image1"/"image2"]:

IMPORTANT: When the switch software is changed (NormalPanel or SmartPanel) and the switch is
rebooted, the switch configuration is removed and the switch runs factory configuration block. Backup the
switch configuration if needed.

Command Line Interface 83

Uploading a software image from the switch

You can upload a software image from the switch to a FTP or TFTP server.

1. At the Boot Options# prompt, enter:

Boot Options# ptimg

2. The system prompts you for information. Enter the desired image:

Enter name of switch software image to be uploaded

["image1"|"image2"|"boot"]: <image>

3. Enter the name or the IP address of the FTP or TFTP server:

Enter hostname or IP address of FTP/TFTP server: <IP address>

4. Enter the name of the file into which the image will be uploaded on the FTP or TFTP server:

Enter name of file on FTP/TFTP server: <filename>

5. Enter the user name, if you are using a FTP server:

Enter username for FTP server or hit return for TFTP server: <userID>

6. Enter the password for the FTP server (if prompted):

Enter password for username on FTP server: <password>

7. The system then requests confirmation of what you have entered. To have the file uploaded, enter y.

image2 currently contains Software Version 1.0.0

Upload will transfer image2 (1889411 bytes) to file "test"

on TFTP server 192.1.1.1.

Confirm upload operation [y/n]: y

Selecting a configuration block

When you make configuration changes to the switch, you must save the changes so that they are retained beyond
the next time the switch is reset. When you execute the save command, your new configuration changes are
placed in the active configuration block. The previous configuration is copied into the backup configuration block.

There is also a factory configuration block. This holds the default configuration set by the factory when the switch
was manufactured. Under certain circumstances, it may be desirable to reset the switch configuration to the default.
This can be useful when a custom-configured switch is moved to a network environment where it will be re­configured for a different purpose.

Use the following procedure to set which configuration block you want the switch to load the next time it is reset:

1. At the Boot Options# prompt, enter:

Boot Options# conf

2. Enter the name of the configuration block you want the switch to use.
The system indicates which configuration block is currently set to be loaded at the next reset, and prompts

you to enter a new choice:

Currently set to use active configuration block on next reset.

Specify new block to use ["active"/"backup"/"factory"]:

Command Line Interface 84

Resetting the switch

You can reset the switch to make your software image file and configuration block changes occur.
Resetting the switch causes the Spanning Tree Protocol to restart. This process can be lengthy, depending on the

topology of your network.
To reset the switch, at the Boot Options# prompt, enter:

>> Boot Options# reset

You are prompted to confirm your request.

Current switch software information

To display the current switch software information, enter the following.

>> Boot Options# cur
Currently set to boot software image2, factory default config block.
Current FLASH software:
image1: version 1.2.0, downloaded 0:15:51 Mon Jan 2, 2006
NormalPanel
image2: version 1.0.0, downloaded 1:32:08 Sun Jan 8, 2006
SmartPanel
boot kernel: version 1.2.0

Use this command to display the image running on the switch, the Configur ation block which the switch runs after
booted, and the switch software stored in image1 and image2.

When NormalPanel is displayed in the software information, the software for conventional Layer2 s witch mode is
stored in the image. When SmartPanel is displayed, the software for SmartPanel mode is stored in the image.
