Chapter 11 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 command to define the macro.

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

–

gigabitethernet module/{first port} - {last port}, where the module is always 0 (for
Catalyst 3560-E switches)

gigabitethernet stack member/module/{first port} - {last port}, where the module is always 0
(for Catalyst 3750-E switches)

–

tengigabitethernet module/{first port} - {last port}, where the module is always 0 (for
Catalyst 3560-E switches)

tengigabitethernet stack member/module/{first port} - {last port}, where the module is
always 0 (for Catalyst 3750-E switches)

–

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, gigabitethernet1/0/1 - 4 is a valid range; gigabitethernet1/0/1-4 is
not a valid range.

Command

Purpose

Step 1

configure terminal

Enter global configuration mode.

Step 2

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 interface ranges.

•

Each interface-range must consist of the same port type.

Step 3

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.

Step 4

end

Return to privileged EXEC mode.

Step 5

show running-config | include define

Show the defined interface range macro configuration.

Step 6

copy running-config startup-config

(Optional) Save your entries in the configuration file.
