Protocols And Standards; Qinq Configuration Task List - HP 5820X series Configuration Manual

The switch determines whether a received frame carries a SVLAN or CVLAN tag by checking the TPID
value. For example, if a frame carries a SVLAN tag with TPID value 0x9100 and a CVLAN tag with TPID
value 0x8100, and the configured TPID value of the SVLAN tag is 0x9100 and that of the CVLAN tag is
0x8200, the switch considers that the frame carries only the SVLAN tag but not the CVLAN tag.
In addition, the systems of different vendors may set the TPID of the outer VLAN tag of QinQ frames to
different values. For compatibility with these systems, modify the TPID value so that the QinQ frames,
when sent to the public network, carry the TPID value identical to the value of a particular vendor to allow
interoperability with the switches of that vendor.
The TPID in an Ethernet frame has the same position with the protocol type field in a frame without a
VLAN tag. To avoid problems in packet forwarding and handling in the network, do not set the TPID
value to any of the values in
