Chapter 1 QinQ Configuration
1-3
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, the S3600 and S5510
series switches allow you to 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 devices 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, you cannot set the TPID value to any of the values in the table below.
