when tagging a received VLAN-VPN frame as needed. When doing that, you should set
the same TPID on both the customer-side port and the service provider-side port.

frame without a VLAN tag. To avoid problems in packet forwarding and handling, you
cannot set the TPID value to any of the values in the table below.
