By changing the CoS/802.1p to Queue mapping (CoS/802.1p to Queue) and the Queue schedule method
and bandwidth allocation (Queue page), it is possible to achieve the desired quality of service 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.
Queue 1 has the lowest priority, queue 4 or 8 has the highest priority.
To map CoS values to egress queues:
STEP 1
STEP 2
• 802.1p—Displays the 802.1p priority tag values to be assigned to an egress queue, where 0 is the
lowest and 7 is the highest priority.
• Output Queue—Select the egress queue to which the 802.1p priority is mapped. Either four or eight
egress queues are supported, where Queue 4 or Queue 8 is the highest priority egress queue and
Queue1 is the lowest priority.
