Configuring Interfaces
Using Interface Configuration Mode
Type
—
10/100/1000 Mbps Ethernet ports, Gigabit Ethernet (gigabitethernet or gi), TenGigabitEthernet
(tengigethernet or te) for or small form-factor pluggable (SFP) module Gigabit Ethernet interfaces.
Module number
—
The module or slot number on the switch.
Port number—The interface number on the switch. The port numbers always begin at 1, starting with the leftmost
port when facing the front of the switch, for example, gigabitethernet 1/1. If there is more than one interface type
(for example, 10/100 ports and SFP module ports), the port numbers restart with the second interface type:
gigabitethernet 1/1.
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.
Procedures for Configuring Interfaces
These general instructions apply to all interface configuration processes.
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)#
2.
Enter the
interface
global configuration command. Identify the interface type and the number of the connector. In
this example, Fast Ethernet port 1 is selected:
Switch(config)#
interface fastethernet0/1
Switch(config-if)#
Note:
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
fastethernet 0/1
,
fastethernet0/1
,
fa 0/1
, or
fa0/1
.
3.
If you are configuring a UNI or ENI, enter the
no shutdown
interface configuration command to enable the interface:
Switch(config-if)#
no shutdown
4.
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.
5.
After you configure an interface, verify its status by using the
show
privileged EXEC commands listed in the
Monitoring and Maintaining the Interfaces, page 45
.
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.
Configuring a Range of Interfaces
You can use the
interface range
global configuration command to configure multiple interfaces with the same
configuration parameters. When you enter the interface range configuration mode, all command parameters that you
enter are attributed to all interfaces within that range until you exit this mode.
Beginning in privileged EXEC mode, follow these steps to configure a range of interfaces with the same parameters:
