Configuring And Using Interface Range Macros - Cisco 3020 - Catalyst Blade Switch Configuration Manual

Using Interface Configuration Mode
When using the interface range global configuration command, note these guidelines:
•
•
•
•
This example shows how to use the interface range global configuration command to set the speed on
ports 1 to 4 to 100 Mbps:
Switch# configure terminal
Switch(config)# interface range gigabitethernet0/1 - 4
Switch(config-if-range)# speed 100
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

Valid entries for port-range:
vlan vlan-ID, where the VLAN ID is 1 to 4094
–
gigabitethernet module/{first port} - {last port}, where the module is always 0
–
port-channel port-channel-number - port-channel-number, where the port-channel-number
–
is 1 to 48
Note When you use the interface range command with port channels, the first and last
port-channel number must be active port channels.
You must add a space between the first interface number and the hyphen when using the
interface range command. For example, the command interface range gigabitethernet0/1 - 4 is a
valid range; the command interface range gigabitethernet0/1-4 is not a valid range.
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 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.
