1.3 Configuring Selective QinQ

The outer VLAN tag inserted by the basic QinQ feature is the VLAN tag corresponding
to the port's default VLAN ID, while the selective QinQ feature can add different VLAN
tags according to the inner VLAN tags carried in received frames.
Frames that do not match tag mapping rules defined for the selective QinQ function are
tagged with the default outer VLAN tag of the port they reach if the basic QinQ function
is enabled. However, if the basic QinQ function is not enabled, the packets will be
dropped.
Follow these steps to configure the selective QinQ function
Enter system view
Enter
Ethernet port
view or port
group view
Configure the outer VLAN
tag to be added to received
frames and enter QinQ
view
Specify the VLANs whose
frames are to be tagged
with the outer VLAN tag
Caution:
Selective QinQ can be configured on access ports/trunk ports/hybrid ports
connecting customer networks to service provider networks.
An inner VLAN tag corresponds to only one outer VLAN tag. To change an outer
VLAN tag, you must remove it first and then reconfigure one.
When you use the qing vid command to configure selective QinQ, the configuration
to remove tags of the packets on the outgoing port of the local switch or the
configuration to permit the packets with tags on the corresponding ports of the other
switches is required.
