Chapter 12 Configuring Interface Characteristics

Using Interface Configuration Mode

The switch supports these interface types:
•
•
•
You can also configure a range of interfaces (see the
page
To configure a physical interface (port), specify the interface type, stack member number, module number,
and switch port number, and enter interface configuration mode.
•
•
•
•
You can identify physical interfaces by looking at the switch. You can also use the show privileged
EXEC commands to display information about a specific interface or all the interfaces. The remainder
of this chapter primarily provides physical interface configuration procedures.
These examples identify interfaces:
•
•
If the switch has SFP modules, the port numbers continue consecutively.To configure the first SFP
module port on stack member 1 with 48 10/100/1000 ports, enter this command:
Configuration examples and outputs in this book might not be specific to your switch, particularly

regarding the presence of a stack member number.

Type—Port types depend on those supported on the switch. Possible types are: Fast Ethernet
(fastethernet or fa) for 10/100 Mb/s Ethernet, Gigabit Ethernet (gigabitethernet or gi) for
10/100/1000 Mb/s Ethernet ports, 10-Gigabit Ethernet (tengigabitethernet or te) for 10,000 Mb/s, or
small form-factor pluggable (SFP) module Gigabit Ethernet interfaces.
Stack member number—The number that identifies the switch within the stack. The switch number
range is 1 to 4 and is assigned the first time the switch initializes. The default switch number, before
it is integrated into a switch stack, is 1. When a switch has been assigned a stack member number,
it keeps that number until another is assigned to it.
You can use the switch port LEDs in Stack mode to identify the stack member number of a switch.
For information about stack member numbers, see the
Module number—The module or slot number on the switch (always 0).
Port number—The interface number on the switch. The port numbers always begin at 1, starting
with the far left port when facing the front of the switch, for example, gigabitethernet1/0/1. For a
switch with 10/100/1000 ports and SFP module ports, SFP module ports are numbered
consecutively following the 10/100/1000 ports.
To configure 10/100/1000 port 4 on a standalone switch, enter this command:
Switch(config)# interface gigabit
tethernet1/0/4
To configure 10/100 port 4 on stack member 3, enter this command:
Switch(config)# interface gigabitethernet3/0/4
Switch(config)# interface gigabitethernet1/0/49
