Procedures For Configuring Interfaces - Cisco WS-C3560-48PS-S Software Configuration Manual

Chapter 10 Configuring Interface Characteristics
To configure a physical interface (port), enter interface configuration mode, and specify the interface type,
module number, and switch port number.

You can identify physical interfaces by physically checking the interface location on the switch. You can
also use the Cisco 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.

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)#
Enter the interface global configuration command. Identify the interface type and the number of the
Step 2
connector. In this example, Gigabit Ethernet port 1 is selected:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)#
Note
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.
After you configure an interface, verify its status by using the show privileged EXEC commands listed
Step 4
in the
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.

Type—Fast Ethernet (fastethernet or fa) for 10/100 Mbps Ethernet or Gigabit Ethernet
(gigabitethernet or gi) for small form-factor pluggable (SFP) Gigabit Ethernet interfaces.
Module number—The module or slot number on the switch (always 0 on the Catalyst 3560 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 SFP module ports), the SFP port
numbers start again from 1: gigabitethernet0/1, gigabitethernet 0/2.
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.
