The Layer 2 header follows the SMD, with the destination address

and the source address. A standard Ethernet frame may not have a

VLAN tag; however, a tag can be added by the switch port manage-

ment. TSN streams typically have a VLAN tag, which contains a

priority (PCP) and a 12-bit VLAN ID. The VLAN ID is used with the

destination address to identify the TSN stream in the lookup tables.

In industrial applications, typical frame sizes are less than 1522

bytes (including the VLAN tag). The switch can support reception

and transmission of frames in excess of 1522 bytes; however,

jumbo packets consume larger blocks of buffer memory and Ether-

net CRC robustness degrades significantly for longer frame sizes,

which can result in undetected errors in these frames. Frames in

excess of the default maximum length (1522 bytes) are recorded in

the receiving port statistics as a large frame error.
