Configuring Interface Characteristics

This example shows how to use the interface range global configuration command to set the speed on
ports 1 to 2 to 100 Mb/s:
Switch# configure terminal
Switch(config)# interface range gigabitethernet1/0/1 - 2
Switch(config-if-range)# speed 100
This example shows how to use a comma to add different interface type strings to the range to enable
Fast Ethernet ports 1 to 3 on switch 1 and Gigabit Ethernet ports 1 and 2 on switch 2 to receive
flow-control pause frames:
Switch# configure terminal
Switch(config)# interface range gigabitethernet1/0/1 - 3, gigabitethernet1/0/1 - 2
Switch(config-if-range)# flowcontrol receive on
If you enter multiple configuration commands while you are in interface-range mode, each command is
executed as it is entered. The commands are not batched and executed after you exit interface-range
mode. If you exit interface-range configuration mode while the commands are being executed, some
commands might not be executed on all interfaces in the range. Wait until the command prompt
reappears before exiting interface-range configuration mode.
Configuring and Using Interface Range Macros
You can create an interface range macro to automatically select a range of interfaces for configuration.
Before you can use the macro keyword in the interface range macro global configuration command
string, you must use the define interface-range global configuration command to define the macro.
Beginning in privileged EXEC mode, follow these steps to define an interface range macro:
Command
Step 1
configure terminal
Step 2
define interface-range macro_name
interface-range
OL-26520-01
You must add a space between the first interface number and the hyphen when using the
interface range command.
For example, interface range gigabitethernet1/0/1 - 4 is a valid range; interface range
gigabitethernet1/0/1-4 is not.
For example, interface range gigabitethernet 0/1 - 4 is a valid range; interface range
gigabitethernet0/1-4 is not.
The interface range command only works with VLAN interfaces that have been configured with
the interface vlan command. The show running-config privileged EXEC command displays the
configured VLAN interfaces. VLAN interfaces not displayed by the show running-config
command cannot be used with the interface range command.
All interfaces defined in a range must be the same type (all Fast Ethernet ports, all Gigabit Ethernet
ports, all EtherChannel ports, or all VLANs), but you can enter multiple ranges in a command.

Purpose
Enter global configuration mode.
Define the interface-range macro, and save it in NVRAM.
•
The macro_name is a 32-character maximum character string.
•
A macro can contain up to five comma-separated interface ranges.
Each interface-range must consist of the same port type.
