Configuring selective QinQ
Configuring an outer VLAN tagging policy
Basic QinQ can only tag received frames with the PVID of the receiving port. Selective QinQ allows
adding different outer VLAN tags based on different inner VLAN tags.
The A5120 EI Switch Series supports the configuration of basic QinQ and selective QinQ at the same
time on a port. When both features are enabled on the port, frames that meet the selective QinQ
condition are handled with selective QinQ before the remaining frames are handled with basic QinQ.
Follow these steps to configure an outer VLAN tagging policy:
Enter interface
view or port
group view
Enter Ethernet
or Layer-2

By default, the SVLAN tag to be
added is the PVID of the
receiving port.
Tag frames of the specified

raw-vlan-id inbound { all | vlan-
list }
CAUTION:
An inner VLAN tag corresponds to only one outer VLAN tag.
To change an outer VLAN tag, you must delete the old outer VLAN tag configuration and configure a new outer
VLAN tag.
