Cisco Cisco SM-X Layer 2 3 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.

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.

The default baud rate of the console connection is 9600.

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 SM-X Layer 2/3 ESM 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

Router(config-if)#no shutdown 

To open a session from the router to the Cisco SM-X Layer 2/3 ESM, use the following command:

Router#service-module gigabitethernet1/0 session

This section describes the different types of interfaces supported by the Cisco SM-X Layer 2/3 ESM with 
references to chapters that contain more detailed information about configuring these interface types.

The Cisco SM-X Layer 2/3 ESM supports the following interface types:

Gigabit Ethernet interfaces

VLAN switched virtual interface (SVI)

This section describes how to perform the initial configuration on the router with a Cisco SM-X Layer 
2/3 ESM installed. This section also describes the initial configuration on the Cisco SM-X Layer 2/3 
ESM itself. Once an IP address has been configured on the Gigabit Ethernet interface on the router 
(representing the Cisco SM-X Layer 2/3 ESM), you can open a console session to the Cisco SM-X Layer 
2/3 ESM and configure its Gigabit Ethernet interface for Layer 2 or Layer 3 features.

Once the Cisco SM-X Layer 2/3 ESM 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.
