Chapter 8 Configuring Interfaces
Defining and Using Interface-Range Macros
• The LED is green (on) when the link is active.
• The LED is off when the link is down.
• The LED is amber when there is a POST failure.
To display the link status, use the show interfaces fastethernet 1 privileged EXEC command.
Defining and Using Interface-Range Macros
You can define an interface-range macro to automatically select a range of interfaces for configuration.
Before using the macro keyword in the interface-range macro command string, you must define the
macro.
To define an interface-range macro, enter this command:
This example shows how to define an interface-range macro named enet_list to select Fast Ethernet
interfaces 5/1 through 5/4:
Switch(config)# define interface-range enet_list fastethernet 5/1 - 4
To show the defined interface-range macro configuration, enter this command:
This example shows how to display the defined interface-range macro named enet_list:
Switch# show running-config | include define
define interface-range enet_list FastEthernet5/1 - 4
Switch#
To use an interface-range macro in the interface range command, enter this command:
This example shows how to change to the interface-range configuration mode using the interface-range
macro enet_list:
Command Purpose
Switch(config)# define interface-range macro_name
{vlan vlan_ID - vlan_ID} | {{fastethernet |
gigabitethernet | tengigabitethernet}
slot/interface - interface}
[, {vlan vlan_ID - vlan_ID} {{fastethernet |
gigabitethernet | tengigabitethernet}
slot/interface - interface}]
Defines the interface-range macro and
saves it in the running configuration file.
Command Purpose
Switch# show running-config
Shows the defined interface-range macro
configuration.
Command Purpose
Switch(config)# interface range macro
name
Selects the interface range to be configured using
the values saved in a named interface-range macro.
