CEP

Customer Edge Port, also known as Selective Q-in-Q or C-tagged Service Interface, is a role that is configured in software as a CEP VMAN port, and connects a VMAN to specific CVLANs based on the CVLAN CVID. The CNP role, which is configured as an untagged VMAN port, connects a VMAN to all other port traffic that is not already mapped to the port CEP role.
