WebEtherType (e.g. 0x0800) Customer payload; PBB defines a 48-bit B-DA and 48-bit B-SA to indicate the backbone source and destination MAC addresses. It also defines a 12-bit B-VID (backbone VLAN ID) and 24-bit I-SID (Service Instance VLAN ID). The bridges in the PBB domain switch based on the B-VID and B-DA values, which contain 60 bits total.

Looking at the Ethernet header format, you will see that the first 6 bytes of the packet are reserved for the destination MAC address, and the … EtherType is a two-octet field in an Ethernet frame. It is used to indicate which protocol is encapsulated in the payload of the frame and is used at the receiving end by the data link layer to determine how the payload is processed. The same field is also used to indicate the size of some Ethernet frames. EtherType … See more In modern implementations of Ethernet, the field within the Ethernet frame used to describe the EtherType can also be used to represent the size of the payload of the Ethernet Frame.
