a Provider Bridge.
A customer-edge port is a C-VLAN component Port

C-VLAN component associated with that port. This
C-VLAN component is uniquely identified within the
Bridge by the port number of the associated Customer
Edge Port.

on a Provider Bridge or within a Provider Edge
Bridge that receives and transmits frame for a
