Figure 8.2.103-1: MAC addresses Detected
Octet 5 shall encode the number of 48-bit MAC addresses.
MAC address values shall be encoded as 12-digit hexadecimal numbers.
The Length of C-TAG field shall indicate the length of the C-TAG field. It shall be set to 0 if the C-TAG field is absent.
When present, the C-TAG field shall be encoded as the Customer-VLAN tag defined in clause 8.2.94, excluding octets 1 to 4.
The Length of S-TAG field shall indicate the length of the S-TAG field. It shall be set to 0 if the S-TAG field is absent.
When present, the S-TAG field shall be encoded as the Service-VLAN Tag defined in clause 8.2.95, excluding octets 1 to 4.
