Chapter 10 Configuring Interface Characteristics
Using Interface Configuration Mode
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 are examples of how to identify interfaces:
• To configure 10/100/1000 port 4 on a standalone switch, enter this command:
Switch(config)# interface gigabitethernet1/0/4
• To configure 10-Gigabit Ethernet port 1 on a standalone switch, enter this command:
Switch(config)# interface tengigabitethernet1/0/1
• To configure 10-Gigabit Ethernet port on stack member 3, enter this command:
Switch(config)# interface tengigabitethernet3/0/1
If the switch has SFP modules, the port numbers continue consecutively.To configure the first SFP
module port on stack member 1 with 16 10/100/1000 ports, enter this command:
Switch(config)# interface gigabitethernet1/0/19
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 number of the connector. In this example, Gigabit Ethernet port 1 on switch 1 is selected:
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)#
Note You do not need to add a space between the interface type and the interface number. For example,
in the preceding line, you can specify either gigabitethernet 1/0/1, gigabitethernet1/0/1,
gi 1/0/1, or gi1/0/1.
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 on page 10-25.
