Chapter 9 Configuring Interfaces

Using Interface Configuration Mode

Using Interface Configuration Mode

The switch supports these interface types:

• Physical ports—switch ports, routed ports, UNIs, NNIs, and ENIs

• VLANs—switch virtual interfaces

• Port-channels—EtherChannel interfaces

You can also configure a range of interfaces (see the “Configuring a Range of Interfaces” section on

page 9-9).

To configure a physical interface (port), specify the interface type, the module number, and the switch port

number, and enter interface configuration mode.

• Type—Fast Ethernet (fastethernet or fa) for 10/100 Mbps Ethernet, Gigabit Ethernet

(gigabitethernet or gi) for 10/100/1000 Mbps Ethernet ports, or small form-factor pluggable (SFP)

module Gigabit Ethernet interfaces.

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

• Port number—The interface number on the switch. The port numbers always begin at 1, starting with

the leftmost port when facing the front of the switch, for example, fastethernet 0/1 or gigabitethernet

0/1. If there is more than one interface type (for example, 10/100 ports and SFP module ports), the

port numbers restart with the second interface type: gigabitethernet 0/1.

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

also use the show privileged EXEC commands to display information about a specific interface or all

the interfaces on the switch. The remainder of this chapter primarily provides physical interface

configuration procedures.

These general instructions apply to all interface configuration processes.

Step 1 Enter the configure terminal command at the privileged EXEC prompt:

Switch# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)#

Step 2 Enter the interface global configuration command. Identify the interface type and the number of the

connector. In this example, Fast Ethernet port 1 is selected:

Switch(config)# interface fastethernet0/1

Switch(config-if)#

Note You do not need to add a space between the interface type and interface number. For example,

in the preceding line, you can specify either fastethernet 0/1, fastethernet0/1, fa 0/1, or fa0/1.

Step 3 If you are configuring a UNI or ENI, enter the no shutdown interface configuration command to enable

the interface:

Switch(config-if)# no shutdown
