QinQ Configuration Task List

Table 1-2 QinQ configuration task list

Configuring Basic QinQ

Configuring Selective QinQ

Configuring the TPID Value in VLAN Tags
QinQ requires configurations only on the service provider network, not on the customer 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.
Basic and selective QinQ should both be configured on the ports connecting customer networks.
Configuring Basic QinQ

Enabling Basic QinQ

Follow these steps to enable basic QinQ:
Enter system view

Enable QinQ on the port(s)
Configuring Selective QinQ

Configuring an Outer VLAN Tagging Policy

Basic QinQ can only tag received frames with the default VLAN tag of the receiving port, while selective
QinQ allows adding different outer VLAN tags based on different inner VLAN tags.
H3C S5120-EI series switches support the configuration of basic QinQ and selective QinQ at the same
time on a port and when the two features are both enabled on the port, frames that meet the selective
QinQ condition are handled with selective QinQ on this port first, and the left frames are handled with
basic QinQ.
