Configuring the TPID value in VLAN tags
NOTE:
QinQ requires configurations only on the service provider network.
QinQ configurations made in Ethernet interface view take effect on the current interface only. Those made in
Layer 2 aggregate interface view take effect on the current aggregate interface and all the member ports in the
aggregation group. Those made in port group view take effect on all member ports in the current port group.
Configure both basic and selective QinQ on the ports that connect customer networks.
Configuring basic QinQ
Enabling basic QinQ
A basic QinQ-enabled port tags an incoming packet with its PVID.
Follow these steps to enable basic QinQ:
Enter interface
view or port
group view
Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view
interface interface-type
interface-number
Required
Use either command.
port-group manual port-group-
name
Required
Disabled by default.
Configuring VLAN transparent transmission
When basic QinQ is enabled on a port, all packets passing through the port are tagged with the port’s
PVID. However, by configuring the VLAN transparent transmission function on a port, you can specify the
port not to add its PVID to packets carrying specific inner VLAN tags when they pass through it, so that
these packets are transmitted in the service provider network with single tags.
Follow these steps to configure VLAN transparent transmission:
Enter interface
view or port
group view
Enter Layer 2
Ethernet interface
