Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
Step 3 Run:
qinq protocol protocol-id
The protocol type of the outer VLAN tag is set.
The qinq protocol command cannot be used on a QinQ interface.
The qinq protocol command is used to identify incoming frames and add or change TPID for
outgoing frames.
By default, the protocol type in the outer VLAN tag is 0x8100.
NOTE
l To implement the connectivity between the devices of different vendors, the protocol type in the outer
VLAN tag must be identified by the peer device.
l The protocol IDs set by the qinq protocol command cannot be the same as well-known protocol IDs.
Otherwise, the interface cannot distinguish packets of these protocols. For example, protocol-id cannot
be set to 0x0806, which is the ARP protocol ID.
