Procedures for Configuring Interfaces 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, Gigabit Ethernet interface 0/1 is selected:
Switch(config)# interface gigabitethernet0/1 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 gigabitethernet 0/1, gigabitethernet0/1, gi 0/1, or gi0/1.
--------------------------------------------------------------------------------
Step 3 Follow each interface command with the interface configuration commands that the interface requires. The commands that you enter define the protocols and applications that will run on the interface. The commands are collected and applied to the interface when you enter another interface command or enter end to return to privileged EXEC mode.
You can also configure a range of interfaces by using the interface range or interface range macro global configuration commands. Interfaces configured in a range must be the same type and must be configured with the same feature options.
Step 4 After you configure an interface, verify its status by using the show privileged EXEC commands listed in the "Monitoring and Maintaining the Interfaces" section.
