Configuring an inner-outer VLAN 802.1p priority mapping
Through QoS policies, the A5120 EI switches achieve the following inner-outer VLAN 802.1p priority
mapping modes:
Marking the 802.1p priorities in outer VLAN tags according to the inner VLAN IDs or the 802.1p
priorities in the inner VLAN tags.
Copying the 802.1p priority in the inner VLAN tags to the outer 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:
Create a class and enter class

traffic classifier classifier-name [
operator { and | or } ]
Required
By default, the operator of a class
is AND.
