User Guidelines
Up to three additional TPIDs can be configured. The 802.1Q TPID is pre-
configured in the system and may not be removed.
It is not possible to configure an inner VLAN TPID value other than 0x8100.
The primary TPID is shown in the EtherType column. The primary TPID is
placed in the outer tag for traffic egressing the interface. The interface will
process traffic as double tagged if any of the configured TPIDs is present in
the frames outer VLAN tag. Traffic with a TPID other than the configured
TPID is processed normally, i.e. as if it is not double tagged.
