Configuring Interface Characteristics

Default Ethernet Interface Configuration

gigabitethernet1/0/8. For a switch with 10/100/1000 ports and SFP module ports, SFP module ports are numbered consecutively following the 10/100/1000 ports.

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 stacking-capable switch:

•To configure 10/100/1000 port 4 on a standalone switch, enter this command:

Switch(config)# interface gigabitethernet1/0/4

•To configure 10/100/1000 port 4 on stack member 3, enter this command:

Switch(config)# interface gigabitethernet3/0/4
