Bridging

Data for VLAN users is carried in tagged MAC frames.

A VLAN-aware bridge also uses the VLAN identifier included in the LAN
frames to make the forwarding decisions.

3.1.4 Frames

Format

3.1.4.1

Ethernet Untagged MAC Frame

Figure 3-2 is an example of an untagged MAC frame.

Figure 4

Ethernet Untagged MAC Frame

The Destination Address (DA) specifies the station(s) for which the
frame is intended. It may be an individual, multicast, or broadcast
address.

•

The Source Address (SA) specifies the station sending the frame.

The Length/Type field (L/T) takes one of two meanings, depending on
its numeric value:

−

If the value is less than or equal to 1500, it indicates the number of
bytes in the subsequent data field.

−

If the value is greater than or equal to 1536, it indicates the nature
of the upper layer protocol.

The Data field contains the upper layer data. A Padding field (Pad) may
be present to warranty a minimum size for the Ethernet frame.
