Using Interface Configuration Mode
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, 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
Switch(config-if)#
Note Entering a space between the interface type and interface number is optional
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 listed
in the “Monitoring and Maintaining the Interfaces” section on page 12-29 .
Enter the show interfaces privileged EXEC command to see a list of all interfaces on or configured for
the switch. A report is provided for each interface that the device supports or for the specified interface.
Configuring a Range of Interfaces
You can use the interface range global configuration command to configure multiple interfaces with
the same configuration parameters. When you enter the interface-range configuration mode, all
command parameters that you enter are attributed to all interfaces within that range until you exit this
mode.
