ABSTRACT:
A network device comprises one or more first ports to receive at least one layer 2 frame of data comprising a media access control (MAC) client data field. An egress policy module adds M bits to the frame of data before the MAC client data field, where M is an integer greater than zero. A second port transmits the frame of data after the M bits are added to the frame of data.
