Clearing Layer 2 Configuration

To clear the Layer 2 configuration on an interface, perform this task:
Command
Step 1
Switch(config)# default interface {fastethernet |
gigabitethernet | tengigabitethernet} slot / port
Step 2
Switch(config-if)# end
Step 3
Switch# show running-config interface
{fastethernet | gigabitethernet |
tengigabitethernet} slot / port
Step 4
Switch# show interfaces [{fastethernet |
gigabitethernet | tengigabitethernet} slot / port ]
switchport
This example shows how to clear the Layer 2 configuration on the Fast Ethernet interface 5/6:
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# default interface fastethernet 5/6
Switch(config)# end
Switch# exit
