Using Wildcards to Identify Interfaces in show Commands

Wildcards (*) identify a group of interfaces in show commands. Table 5-4provides examples of wildcard usage to identify a group of interfaces.

Table 5-4 Examples of Wildcard Usage

Wildcard Syntax	Description

*	Specifies all interfaces

gi*	Specifies all Gigabit-Ethernet interfaces in the
	system

gi0/1/*	Specifies all Gigabit-Ethernet interfaces in rack 0,
	slot 1

gi0/3/4.*	Specifies all subinterfaces for Gi0/3/4

Note The wildcard (*) must be the last character in the interface name.

Example

In the following example, the configuration for all Gigabit-Ethernet interfaces in rack 0, slot 1 appears:

RP/0/RSP1/CPU0:router# show running-config interface Gi0/1/*

interface Gi0/1/0/0

ipv4 address 10.2.3.4 255.255.255.0 gi

interface Gi0/1/0/1

ipv4 address 10.2.3.5 255.255.255.0 gi

crc 32

!

keepalive disable

interface Gi0/1/0/2

ipv4 address 10.2.3.6 255.255.255.0 gi

crc 32

!

keepalive disable

interface Gi0/1/0/3

ipv4 address 10.2.3.7 255.255.255.0 gi

crc 32

!

keepalive disable

--More--

In the following example, the state of all Gigabit-Ethernet interfaces appears:

RP/0/RSP1/CPU0:router# show interfaces gi* brief
