Protocols And Standards; Qinq Configuration Task List - HP A3100-8 v2 SI Configuration Manual

The switch determines whether a received frame carries a VLAN tag by checking the TPID value. For
example, if a frame carries a VLAN tag with TPID value 0x8100, but the configured TPID value is 0x9100,
the switch considers that the frame does not carry any VLAN tag.
The systems of different vendors might 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, allowing
interoperability with the switches of that vendor.
The TPID in an Ethernet frame has the same position as 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 reserved values.
