Chapter9 Configuring Interface Characteristics
Using Interface 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 comm a nd to d efine th e m a cro.
Beginning in privileged EXEC mode, follow these steps to define an interface range macro:
Use the no define interface-range macro_name global configuration command to delete a macro.
When using the define interface-range global configuration command, note these guidelines:
Valid entries for interface-range:
vlan vlan-ID - vlan-ID, where the VLAN ID is 1 to 4094
fastethernet module/{first port} - {last port}, where the module is always 0
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 ranges 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 entering an
interface-range. For example, gigabitethernet0/1- 2 is a valid range; gigabitethernet0/1-2 is not
a valid range.
The VLAN interfaces must have been configured with the interface vlan command. The show
running-config privileged EXEC command displays the configured VLAN interfaces. VLA N
interfaces not displayed by the show running-config command cannot be used as interface-ranges.
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 define interface-range macro_name
interface-range 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 interfa ce ranges.
Each interface-range must consist of the same port type.
Step3 no shutdown Enable the port, if necessary. By default, UNIs are disabled, and NNIs
are enabled.
Step4 interface range macro macro_name Select the interface range to be configured 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.
Step5 end Return to privileged EXEC mode.
Step6 show running-config | include define Show the defined interface range macro configuration.
Step7 copy running-config startup-config (O ptional) Save your entri es in the co nfiguration file.
