How to Configure the Cisco EtherSwitch Service Module

The interface numbering format on the Cisco EtherSwitch service module is stack-member-number/0/switch-port. For more detailed information about interface types, see the Catalyst 3750 Switch Software Configuration Guide, Cisco IOS Release 12.2 at the following URL:

Using Interface Configuration Mode

You can configure the individual Cisco EtherSwitch service module physical interfaces (ports) through the interface configuration mode on the CLI. The port numbering scheme that you use in interface configuration mode is interface type stack member number/0/port number.

Note For Cisco EtherSwitch service modules or switches that do not have StackWise interfaces, the stack member number is 1 by default but changeable through Cisco IOS software or bootloader.

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

•Stack member number—The number used to identify the Cisco EtherSwitch service module or switch within the stack. The Cisco EtherSwitch service module or switch number ranges from 1 to 9 and is assigned the first time the service module or switch initializes. The default Cisco EtherSwitch service module or switch number, before it is integrated into a switch stack, is 1; when a service module or switch has been assigned a stack member number, it keeps that number until another is assigned to it.

You can use the Cisco EtherSwitch service module or switch port LEDs in stack mode to identify the stack member number of a service module or switch.

•Module number—The module slot number on the Cisco EtherSwitch service module or switch (always 0 on the service module or switch).

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

You can identify physical interfaces by physically checking the interface location on the

Cisco 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 EtherSwitch service module.

These are examples of specifying interfaces:

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

Enhanced EtherSwitch (config)# interface gigabitethernet1/0/4

•To specify Fast Ethernet port 4 on stack member 3, enter this command in global configuration mode:

Enhanced EtherSwitch (config)# interface fastethernet3/0/4
