Configuring a Layer 2 Ethernet interface
Configure the Layer 2 Ethernet interface connected to the CE to create a Layer 2 link between the PE and
CE.
The Layer 2 interface type determines the access mode of the AC. On the Layer 2 Ethernet interface, you
can use the access-mode keyword of the ac interface command to specify the access mode as Ethernet
(the default) or VLAN.
Configuring a service instance on a Layer 2 Ethernet interface
When the PE connects to a CE through a Layer 2 Ethernet interface, you can configure a service instance
on the Layer 2 Ethernet interface to match specific packets from the AC.
To configure a service instance:
