• Configure a traffic behavior to tag packets with an outer VLAN tag.
• Create a QoS policy and associate the class with the behavior in the policy.
• Apply the QoS policy to the port that connects to the user.
Follow these steps to configure selective QinQ:

CAUTION:
•
Selective QinQ has higher priority than basic QinQ. A received frame is tagged with an outer VLAN ID
based on basic QinQ only after it fails to match the match criteria defined in the traffic class.
• Selective QinQ is achieved through QoS policies. For more information about QoS policies, see ACL
and QoS Configuration Guide.
Configuring an inner-outer VLAN 802.1p priority mapping
Through QoS policies, the S10500 Switch Series marks the 802.1p priorities in outer VLAN tags
according to the inner VLAN IDs or the 802.1p priorities in the inner VLAN tags:
Follow these steps to mark the 802.1p priorities in outer VLAN tags according to the inner VLAN IDs or
the 802.1p priorities in the inner VLAN tags:
