Using Interface Configuration Mode

Port number—The interface number on the switch. The 10/100/1000 port numbers always begin
at 1, starting with the far left port when facing the front of the switch, for example,
gigabitethernet1/0/1 or gigabitethernet1/0/8.

gigabitethernet1/0/1 or gigabitethernet1/0/8.
On a switch with 10/100/1000 ports and Cisco TwinGig Converter Modules in the 10-Gigabit
Ethernet module slots, the port numbers restart with the 10-Gigabit Ethernet ports:
tengigabitethernet1/0/1.
Ethernet module slots, the port numbers restart with the 10-Gigabit Ethernet ports:
tengigabitethernet1/0/1.
On a switch with 10/100/1000 ports and Cisco dual SFP X2 converter modules in the 10-Gigabit
Ethernet module slots, the SFP module ports are numbered consecutively following the 10/100/1000
interfaces. For example, if the switch has 24 10/100/1000 ports, the SFP module ports are
gigabitethernet1/0/25 through gigabitethernet1/0/28.

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 on a Catalyst 3750-E switch:
•
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 24 10/100/1000 ports, enter this command:
module port on stack member 1 with 24 10/100/1000 ports, enter this command:
Switch(config)# interface gigabitethernet1/0/25
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 (only
Catalyst 3750-E switches), and the number of the connector. In this example, Gigabit Ethernet port 1 on
switch 1 is selected:
Catalyst 3750-E switches), 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.
