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 will be the default CoS/802.1p priority assigned to the
ingress ports.
Default Mapping Queues
By changing the CoS/802.1p to Queue mapping and the Queue schedule method
and bandwidth allocation, it is possible to achieve the desired quality of services
in a network.
CoS/802.1p to Queue mapping is applicable only if CoS/802.1p is the trusted
mode and the packets belong to flows that are CoS trusted.
