Chapter 12 Configuring Interface Characteristics
Using Interface Configuration Mode
Identify the interface type and the interface number, Gigabit Ethernet port 1 in this example:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)#
Note Entering a space between the interface type and interface number is optional
Step 3 Follow each interface command with the 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.
Step 4 After you configure an interface, verify its status by using the show privileged EXEC commands listed
in the “Monitoring and Maintaining the Interfaces” section on page 12-37.
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-r ange configuration mode, all command
parameters that you enter are attributed to all interfaces within that range until you exit this mode.
Beginning in p rivileged EXEC mode, follow th ese steps to configure a range of interfaces with the
same parameters:
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface range {port-range | macro
macro_name}
Specify the range of interfaces (VLANs or physical por ts) to be
configured, and enter interface-range configuration mode.
You can use the interface range command to configure up to five
port ranges or a previously defined macro.
The macro variable is explained in the “Configuring and Using
Interface Range Macros” section on page 12-19.
In a comma-separated port-range, you must enter the interface
type for each entry and enter spaces before and after the comma.
In a hyphen-separated port-range, you do not need to re-enter the
interface type, but you must enter a space before the hyphen.
Step 3 Use the normal configuration commands to apply the configuration
parameters to all interfaces in the range. Each command is executed
as it is entered.
Step 4 end Return to privileged EXEC mode.
