Ethernet subinterface, both the default PW data encapsulation type and default access mode are
VLAN.
The PW data encapsulation type and AC access mode determine how the VLAN tag is processed by
a PE. Therefore, the PW data encapsulation types and AC access modes on the local PE and the
peer PE must match.
To configure the interface with Ethernet or VLAN encapsulation:
