Examples
The following example shows how to enable Layer 2 transport port mode on an Ethernet interface and enter
Layer 2 transport configuration mode:
RP/0/RSP0/CPU0:router# configure
RP/0/RSP0/CPU0:router(config)# interface GigabitEther 0/2/0/0
RP/0/RSP0/CPU0:router(config-if)# l2transport
RP/0/RSP0/CPU0:router(config-if-l2)#
The following example shows how to use the l2transport keyword in the interface command:
RP/0/RSP0/CPU0:router# configure
RP/0/RSP0/CPU0:router(config)# interface GigabitEther 0/2/0/0 l2transport
RP/0/RSP0/CPU0:router(config-if)# encapsulation dot1q 200
RP/0/RSP0/CPU0:router(config-if-l2)#commit
The following example shows how to use the l2transport command on an Ethernet subinterface:
Ensure that the l2transport command is applied on the same line as the interface command for the
Ethernet subinterface.

To configure l2transport on an Ethernet subinterface, ensure that the main interface is configured as a
Layer 3 interface.
