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.
Step 2

Enter the interface global configuration command. Identify the interface type, the switch number, and the interface number. In this example, Gigabit Ethernet port 1 on switch 1 is selected:
Switch(config)# interface gigabitethernet1/0/1

Step 3

Follow each interface command with the 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
