TPID setting and priority duplication and mapping
The Ethernet frame tag includes four fields-TPID (Tag Protocol Identifier), User
Priority, CFI and VLAN ID. By default, TPID uses 0x8100 specified in IEEE
802.1Q. Some vendors
’ devices, however, set the TPID of the outer tag of
packes to 0x9100 or other values. To compatible with these devices, QinQ
offers the function to configure the TPID of packets based on port. In the course
of packet transmission, the TPID of the outer VLAN tag of packets are replaced
with the set value.
Priority duplication refers to duplicating the priority of inner tag (user tag) to
outer tag (ISP tag) when adding outer tag.
Priority mapping refers to setting the priority of outer tag (ISP tag) by inner tag
(user tag) when adding outer tag.
MAC address duplication
For flow-based flexible QinQ, the switch learns VID of native VLAN. Hence, in
case of flow-based VLAN translation, when the peer sends back packets,
flooding may occur for the MAC address cannot be obtained.
