Chapter 12 Configuring Interface Characteristics
Using Interface Configuration Mode
Using Interface Configuration Mode
The switch supports these interface types:
•
Physical ports—switch ports
• VLANs—switch virtual interfaces
•
Port channels—EtherChannel interfaces
You can also configure a range of interfaces (see the “Configuring a Range of Interfaces” section on
page 12-12 ).
To configure a physical interface (port), specify the interface type, stack member number, module number,
and switch port number, and enter interface configuration mode.
• 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 “Member Numbers” section on page 6-6 .
• 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.
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:
• 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
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:
Switch(config)# interface gigabitethernet1/0/49
Note Configuration examples and outputs in this book might not be specific to your switch, particularly
regarding the presence of a stack member number.
