Configuring And Using Interface-Range Macros - Cisco Catalyst 2950 Software Configuration Manual

Chapter 10 Configuring Interface Characteristics
•
This example shows how to use the interface range global configuration command to set the speed on
Fast Ethernet interfaces 0/1 to 0/5 to 100 Mbps:
Switch# configure terminal
Switch(config)# interface range fastethernet0/1 - 5
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 all
Fast Ethernet interfaces in the range 0/1 to 0/3 and Gigabit Ethernet interfaces 0/1 and 0/2:
Switch# configure terminal
Switch(config)# interface range fastethernet0/1 - 3, gigabitethernet0/1 - 2
Switch(config-if-range)# no shutdown
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 together 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
Step 3
interface range macro macro_name
Step 4
end
Step 5 show running-config | include define
Step 6
copy running-config startup-config
78-11380-12
All interfaces in a range must be the same type; that is, all Fast Ethernet ports, all Gigabit Ethernet
ports, all EtherChannel ports, or VLAN interfaces.
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.
•
You do not need to enter spaces before or after the comma.
Each interface-range must consist of the same port type.
•
Select the interface range to be configured by using the values saved
in the interface-range macro called macro_name.
You can now use the normal configuration commands to apply the
configuration to all interfaces in the defined macro.
Return to privileged EXEC mode.
Show the defined interface-range macro configuration.
(Optional) Save your entries in the configuration file.
