Mapping CoS/802.1p to a Queue
The CoS/802.1p to Queue page maps 802.1p priorities to egress queues. The
CoS/802.1p to Queue Table determines the egress queues of the incoming
packets based on the 802.1p priority in their VLAN Tags. For incoming untagged
packets, the 802.1p priority is the default CoS/802.1p priority assigned to the
ingress ports.
