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:

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

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.

• Type — Fast Ethernet (fastethernet or fa) for 10/100-Mbps Ethernet or Gigabit Ethernet (gigabitethernet or gi) for 10/100/1000-Mbps Ethernet ports.
• Module number — The 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:

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.

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:

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

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:

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

When password recovery is disabled, access to the boot loader prompt through the password-recovery mechanism is disallowed even though the password-recovery mechanism has been triggered. If you agree to let the system be reset to the default system configuration, access to the boot loader prompt is then allowed, and you can set the environment variables.
