Chapter 9 Configuri ng th e Switch Interfaces Using the Interface Command
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
Step 2 Ente r th e interface global configur atio n c om ma nd. I de nti fy t he i nte rfac e t yp e an d t he num be r of t he
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 your particular interface
requires. The commands 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
ent er end to return to privileged EXEC mode.
You can al so configure a range of inte rfaces by using the interface range or interface range macro
global configurati on comm ands. Inte rfaces co nfigured in a range must be the same type and must be
configured with the same feature options.
Step 4 After you c onfigure a n int erface, verify its stat us by using th e show privileged EXEC c omma nds li sted
in the “Monitoring and Maintaining the Interfaces” section o n page 9-16.
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:
