default interface
Command
Default Interface
UseThis command allows you to quickly revert an interface back to its default configuration.
If you have a lot of changes, this is much faster than using the no version of every command on the interface.
Syntax
Router(config)#default interface <interface>
Example
In this example we will revert R1's Fa0/0 interface back to its default configuration.
First lets have a look at Fa0/0's current config.
R1(config)#do show run int fa0/0
Building configuration...
Current configuration : 210 bytes
!
interface FastEthernet0/0
description "This is a description"
bandwidth 100000
ip address 10.1.1.1 255.255.255.0
ip nat inside
ip virtual-reassembly
ip ospf cost 1
delay 4
speed 100
full-duplex
end
R1(config)# |
Now lets default the interface.
R1(config)#default interface fa0/0
Building configuration...
Interface FastEthernet0/0 set to default configuration
R1(config)#
*Mar 1 00:42:00.851: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 10.1.1.2 (FastEthernet0/0) is down: interface down
R1(config)#
R1(config)#do show run int fa0/0
Building configuration...
Current configuration : 73 bytes
!
interface FastEthernet0/0
no ip address
duplex auto
speed auto
end
R1(config)#
