This is a cool command to erase just the configuration for a particular interface in a Cisco Switch or a Cisco Router.

In the following example we will configure the interface fast Ethernet 0/9  to default configuration

Current Configuration for fast Ethernet 0/9  

ITKE-Cisco#sho running-config interface fastEthernet 0/9

Building configuration…


Current configuration : 85 bytes


interface FastEthernet0/9

 switchport access vlan 100

 switchport mode access




Now we will configure the fast Ethernet 0/9 to default configuration using the following command

“default interface fastEthernet 0/9” 

ITKE-Cisco#configure t

Enter configuration commands, one per line.  End with CNTL/Z.

ITKE-Cisco(config)#default interface fastEthernet 0/9

Interface FastEthernet0/6 set to default configuration



Running configuration for fast Ethernet 0/9 after configuring to default settings

ITKE-Cisco#sho running-config interface fastEthernet 0/9

Building configuration…


Current configuration : 68 bytes


interface FastEthernet0/9

 switchport mode dynamic desirable
