Using the Interface Command

Figure 9-1
Using the Interface Command
To configure a physical interface (port), use the interface global configuration command to enter interface
configuration mode and to specify the interface type, slot, and number.

You can identify physical interfaces by physically checking the interface location on the switch. You can
also use the IOS 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.
This section describes how to configure all types of interfaces and how to configure a range of interfaces:

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

Type—Fast Ethernet (fastethernet or fa) for 10/100 Ethernet or Gigabit Ethernet (gigabitethernet or
gi)
Slot—The slot number on the switch (always 0 on this switch).
Port number—The interface number on the switch. The port numbers always begin at 1, starting at
the left when facing the front of the switch, for example, fastethernet 0/1, fastethernet 0/2. If there
is more than one media type (for example, 10/100 ports and Gigabit Ethernet ports), the port number
starts again with the second media: gigabitethernet 0/1, gigabitethernet 0/2.
