By configuring different match criteria, you can add outer VLAN tags to packets more flexibly. For
example, you can add an outer VLAN tag to packets with the specified source IP/source MAC,
add different outer VLAN tags to packets of different protocols (matched through ACL), or add
different outer VLAN tags to packets with different priorities.
Configuring the TPID Value in VLAN Tags
You can configure the TPID value in VLAN tags in system view, where the configuration takes effect on
all ports of the device.
