Cisco Enhanced EtherSwitch Service Modules Configuration Guide


The Cisco enhanced EtherSwitch service modules provide Cisco 2900 series routers and Cisco 3900 series routers the ability to use Cisco enhanced EtherSwitch service modules as independent Layer 2 and Layer 3 switches when running Cisco IOS.


Note This document describes the following Cisco enhanced EtherSwitch service modules only: SM-ES2-16-P, SM-ES3-16-P, SM-ES3G-16-P, SM-ES2-24, SM-ES2-24-P, SM-ES3-24-P, SM-ES3G-24-P, SM-D-ES2-48, SM-D-ES3-48-P, and SM-D-ES3G-48-P. For information about other Cisco Ethernet switch network modules, see the Connecting Cisco Ethernet Switch Network Modules to the Network document.


The Cisco enhanced EtherSwitch service modules connect to Cisco 2900 series and Cisco 3900 series routers through the service module console Gigabit Ethernet port to a serial interface on the router. This Gigabit Ethernet port gives the appearance of a Layer 3 port to the router.

The Cisco enhanced EtherSwitch service modules also provide a physical Gigabit Ethernet serializer/deserializer integrated circuit transceiver High-Speed Intrachassis Module Interconnect (HIMI) interface. In the Cisco 2900 series and Cisco 3900 series routers, the HIMI link on the Cisco enhanced EtherSwitch service modules is connected to the router internal Gigabit Ethernet backplane. This link is used for interconnection between other interface cards or network modules attached to the router Gigabit Ethernet backplane bypassing the router host CPU, thus increasing CPU performance by decreasing CPU processing.

To access the Cisco enhanced EtherSwitch service module, establish a session from the router over the serial interface to the Cisco enhanced EtherSwitch service module. To exchange and monitor control messages between the Cisco enhanced EtherSwitch service module and the router, a Router Blade Configuration Protocol (RBCP) stack operates concurrently on active IOS sessions running on both the router and the service module.

How to Configure the Cisco Enhanced EtherSwitch Service Module on the Router

This section contains the following procedures:

Accessing the CLI Through a Console Connection or Through Telnet (required)

Understanding Interface Types on the Cisco Enhanced EtherSwitch Service Modules (optional)

Using Interface Configuration Mode

Configuring the Cisco Enhanced EtherSwitch Service Module in the Router

Shutting Down, Resetting, and Reloading the Cisco Enhanced EtherSwitch Service Module

Accessing the CLI Through a Console Connection or Through Telnet

Before you can access the Cisco enhanced EtherSwitch service module CLI, you must connect to the host router through the router console or through Telnet. Once you are connected to the router, you must configure an IP address on the Gigabit Ethernet interface connected to the Cisco enhanced EtherSwitch service module. Open a session to the Cisco enhanced EtherSwitch service module using the service-module gigabitethernet x/0 session command in privileged EXEC mode on the router.

You can use one of these methods to establish a connection to the Cisco enhanced EtherSwitch service module:

Connect to the router console using Telnet or Secure Shell (SSH) and open a session to the switch using the service-module gigabitethernet x/0 session command in privileged EXEC mode on the router.


Note When connecting to the router through the console using Telnet or SSH from a client station, you must have IP connectivity from the station to the switch.


Use any Telnet TCP/IP or encrypted SSH package from a remote management station. The internal interface must have network connectivity with the Telnet or SSH client, and the internal interface must have an enable secret password configured. After you connect through the CLI, a Telnet session, or an SSH session, the user EXEC prompt appears on the management station.

The Cisco enhanced EtherSwitch service module or switch supports up to 5 simultaneous secure SSH sessions and up to 16 simultaneous Telnet sessions. Changes made by one Telnet user are reflected in all other Telnet sessions.

You can use the following configuration examples to establish a connection:

To configure an IP address and subnet mask for Gigabit Ethernet interface (gigabitethernet 1/0) on the router, use the following command:

Router(config)#interface gigabitethernet 1/0
Router(config-if)#ip address 10.1.1.111 255.255.255.252
 
   

To open a session from the router to the Cisco enhanced EtherSwitch service module, use the following command:

Router#service-module gigabitethernet1/0 session

Understanding Interface Types on the Cisco Enhanced EtherSwitch Service Modules

This section describes the different types of interfaces supported by the Cisco enhanced EtherSwitch service module with references to chapters that contain more detailed information about configuring these interface types.

The Cisco enhanced EtherSwitch service module supports the following interface types:

Fast Ethernet interfaces

Gigabit Ethernet interfaces

VLAN switched virtual interface (SVI)

Using Interface Configuration Mode

You can configure the individual Cisco enhanced EtherSwitch service module physical interfaces (ports) through the interface configuration mode on the CLI.

TypeFast Ethernet (fastethernet or fa) for 10/100-Mbps Ethernet or Gigabit Ethernet (gigabitethernet or gi) for 10/100/1000-Mbps Ethernet ports.

Module numberThe module slot number on the Cisco enhanced EtherSwitch service module or switch (always 0 on the service module or switch).

Port number—The interface number on the Cisco enhanced EtherSwitch service module or switch. The port numbers always begin at 1, starting at the right when facing the front of the Cisco enhanced EtherSwitch service module, for example, gigabitethernet 0/1, gigabitethernet 0/2 with 0/1 on the top, 0/2 on the bottom, 0/3 on the top, 0/4 on the bottom and so on.

You can identify physical interfaces by physically checking the interface location on the
Cisco enhanced EtherSwitch service module. You can also use the Cisco IOS show privileged EXEC commands to display information about a specific interface or all the interfaces on the Cisco switching
service module.

These are examples of specifying interfaces:

To specify Gigabit Ethernet port 4 on a standalone Cisco enhanced EtherSwitch service module, enter this command in global configuration mode:

Enhanced Switching (config)# interface gigabitethernet 0/4
 
   

Configuring the Cisco Enhanced EtherSwitch Service Module in the Router

This section describes how to perform the initial configuration on the router with a Cisco enhanced EtherSwitch service module installed. This section also describes the initial configuration on the Cisco enhanced EtherSwitch service module itself. Once an IP address has been configured on the Gigabit Ethernet interface on the router (representing the Cisco enhanced EtherSwitch service module), you can open a console session to the Cisco enhanced EtherSwitch service module and configure its Fast Ethernet and Gigabit Ethernet interfaces for Layer 2 or Layer 3 functionality.

Once the Cisco enhanced EtherSwitch service module interface has been configured and you boot up the service module image, you can switch back and forth between the router and the service module.


Note During auto boot loader operation, you are not presented with the boot loader command-line prompt. You gain access to the boot loader command line if the switch is set to manually boot or, if an error occurs, the operating system (a corrupted Cisco IOS image) is loaded. You can also access the boot loader if you have lost or forgotten the switch password.

Troubleshooting the Cisco Enhanced EtherSwitch Service Module Software

This section describes how to troubleshoot the Cisco enhanced EtherSwitch service module:

Recovering from a Corrupted Software Image Using Xmodem

Recovering from a Lost or Forgotten Password

Recovering from a Lost or Forgotten Password When Password Recovery Is Disabled

Recovering from a Corrupted Software Image Using Xmodem

This section describes how to recover from a corrupted software image by using Xmodem.


Note The router should have the switch image in the router flash memory or have network connectivity to the TFTP server.


The Cisco enhanced EtherSwitch service module software can be corrupted while upgrading the software, by downloading the wrong file to the Cisco enhanced EtherSwitch service module, and by deleting the image file. In all of these cases, the service module does not pass the power-on self-test (POST) and there is no connectivity.

This procedure uses the Xmodem Protocol to recover from a corrupt or wrong image file. Many software packages support the Xmodem Protocol, and this procedure is largely dependent on the emulation software you are using.

To start the Xmodem protocol process, issue the password reset command. After you issue the password reset command, the following message appears:

Password reset process is complete...
 
   
 
   
The system has been interrupted prior to initializing the
flash filesystem.  The following commands will initialize
the flash filesystem, and finish loading the operating 
system software:
 
   
    flash_init
    load_helper
    boot
 
   
 
   
Switch: 

Restrictions

This procedure is recommended only for recovery of a corrupted image. To perform this procedure, the Cisco enhanced EtherSwitch service module must be at the boot loader prompt, and the console from the router to the Cisco enhanced EtherSwitch service module must be disconnected for the Xmodem Protocol to work.

SUMMARY STEPS

1. service-module interface slot/port password-reset

2. flash_init

3. control+shift+6 x (Use x to get back to the router prompt.)

4. disconnect

5. copy flash: xmodem: or copy tftp: xmodem:

6. service-module interface slot/port session

7. dir flash:

8. boot flash:image

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

service-module interface slot/port password-reset

Example:

Router# service-module gigabitethernet2/0 password-reset

Ensures that the switch stays at the boot loader prompt, so that you can copy a new image through the Xmodem Protocol.

Step 2 

flash_init

Example:

Switch: flash_init

Initializes the flash memory file system on the switch.

Step 3 

control+shift+6 x

Example:

Switch: control+shift+6 x

Returns you to the router console while keeping the console session to the switch intact.

(Use x to get back to the router prompt.)

Step 4 

disconnect

Example:

Router# disconnect 1

Disconnects the switch session to begin the Xmodem download.

Step 5 

copy flash: xmodem:

Example:

Router# copy flash: xmodem:

Starts the file transfer from the router flash memory by using the Xmodem Protocol from the router prompt.

Note Use this command to download the software image from the router flash memory. Use this command from the router prompt.

or

copy tftp: xmodem:

Example:

Router# copy tftp: xmodem:

or

Starts the file transfer from a TFTP server from the router prompt.

Note Use this command to download the software image from a TFTP server. Use this command only if the image is not on the router flash memory.

Step 6 

service-module interface slot/port session

Example:

Router# service-module gigabitethernet1/0 session

Connects to the service module and opens a Cisco enhanced EtherSwitch service module session.

Step 7 

dir flash:

Example:

switch: dir flash:

Displays a list of all files and directories in flash memory on the service module.

Step 8 

boot flash:image

Example:

switch> boot flash:c2960sm-lanbasek9-mz.image

Boots the Cisco enhanced EtherSwitch service module image if all files and directories are in flash memory on the service module.

Troubleshooting

If the downloaded image (files and directories) are not in flash memory on the Cisco enhanced EtherSwitch service module, repeat Step 1 through Step 6. If the procedure fails again, ensure that your TFTP connection is up and that your TFTP session is open when you download the image.

Recovering from a Lost or Forgotten Password

This section shows how to recover from a lost or forgotten password.

The default configuration for the Cisco enhanced EtherSwitch service module allows an end user to recover from a lost password by entering a new password.

During auto boot loader operation, you are not presented with the boot loader command-line prompt. You gain access to the boot loader command line if the switch is set to manually boot or, if an error occurs, the operating system (a corrupted Cisco IOS image) is loaded. You can also access the boot loader if you have lost or forgotten the switch password.


Note The default configuration for Cisco enhanced EtherSwitch service modules allows an end user to recover from a lost password. The password recovery disable feature allows the system administrator to protect access to the switch password by disabling part of this functionality and allowing the user to interrupt the boot process only by agreeing to set the system back to the default configuration. With password recovery disabled, the user can still interrupt the boot process and change the password, but the configuration file (config.text) and the VLAN database file (vlan.dat) are deleted.


Prerequisites

This recovery procedure requires you have physical access to the service module.

SUMMARY STEPS

1. service-module interface slot/port password-reset

2. flash_init

3. rename

4. boot

5. copy flash:

6. configure terminal

7. enable secret password

8. exit

9. copy running-configuration startup-configuration

10. reload

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

service-module interface slot/port password-reset

Example:

Router# service-module gigabitethernet1/0 password-reset

Enables password recovery.

Step 2 

flash_init

Example:

Switch: flash_init

Initializes the flash memory file system.

Step 3 

rename

Example:

Switch# rename flash:config.text flash:config.text.old

Renames the configuration file to config.text.old.

Step 4 

boot [-x] [-v] [device:][imagename]

Example:

Switch: boot

Use the boot command to boot up an external process.

Step 5 

copy flash:

Example:

Switch: copy flash:config.text system:running-config

Copies the configuration file into memory.

Step 6 

configure terminal

Example:

Switch# configure terminal

Enters global configuration mode.

Step 7 

enable secret password

Example:

Switch(config)# enable secret 5 $1$LiBw$0Xc1wyT.PXPkuhFwqyhVi0

Sets the password.

The secret password can be from 1 to 25 alphanumeric characters.

It can start with a number.

It is case sensitive.

It allows spaces but ignores leading spaces.

Step 8 

exit

Example:

Switch(config)# exit

Returns you to privileged EXEC mode.

Step 9 

copy running-configuration startup-configuration

Example:

Switch# copy running-config startup-config

Copies the configuration from the running configuration file to the switch startup configuration file.

This procedure is likely to leave your Cisco enhanced EtherSwitch service module virtual interface in a shut down state.

You can see which interface is in this state by entering the show running-configuration privileged EXEC command.

To reenable the interface, enter the interface vlan vlan-id global configuration command, and specify the VLAN ID of the shut down interface. With the Cisco enhanced EtherSwitch service module in interface configuration mode, enter the no shutdown command.

Step 10 

reload

Example:

Switch# reload

Reloads the switch.

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

service-module interface slot/port password-reset

Example:

Router# service-module gigabitethernet1/0 password-reset

Resets the password on the router.

Step 2 

service-module interface slot/port session

Example:

Router# service-module gigabitethernet1/0 session

Connects to the service module and opens a service module session.

Entering no leaves the current configuration file intact, so you can rename it.

Entering yes deletes the configuration file.

Note This configuration can only be done if the service-module session command is entered within 50 seconds after entering the service-module password-reset command.

Step 3 

dir flash:

Example:

rommon> dir flash:

Displays a list of all files and directories in flash memory on the service module.

Step 4 

load_helper filesystem:/file-url ...

Example:

Switch: load_helper flash: xyz

Loads and initializes one or more helper images.

Step 5 

boot

Example:

Switch: boot

Boots the system.

Step 6 

enable

Example:

Switch# enable

Enters privileged EXEC mode from the service module prompt.

Step 7 

configure terminal

Example:

Switch# configure terminal

Enters global configuration mode.

Step 8 

enable secret password

Example:

Switch(config)# enable secret 5 $1$LiBw$0Xc1wyT.PXPkuhFwqyhVi0

Changes the password.

The secret password can be from 1 to 25 alphanumeric characters.

It can start with a number.

It is case sensitive.

It allows spaces but ignores leading spaces.

Step 9 

exit

Example:

Switch(config)# exit

Returns you to privileged EXEC mode.

Step 10 

copy running-configuration startup-configuration

Example:

Switch# copy running-config startup-config

Copies the configuration from the running configuration file to the switch startup configuration file.

This procedure is likely to leave your Cisco enhanced EtherSwitch service module virtual interface in a shut down state.

You can see which interface is in this state by entering the show running-configuration privileged EXEC command.

To reenable the interface, enter the interface vlan vlan-id global configuration command, and specify the VLAN ID of the shut down interface. With the Cisco enhanced EtherSwitch service module in interface configuration mode, enter the no shutdown command.

Step 11 

reload

Example:

Switch# reload

Reloads the switch.

Note This does not set the environment variables if the switch is set to auto boot.

Step 12 

set

Example:

Switch# set

Lists all environment variables, including the current baud rate.

Example

Sample Output for the set Command

The following example shows what appears when you enter the set command:

Switch: set
 
   
BAUD=9600
