Mapping Priority to Classes (Queues)
The 802.1P User Priority Page allows network managers to assign priority tags to classes (queues). If a network manager
defines a priority of 01 to Class 3, all packets arriving with an assigned value of 01 are sent to class (queue) 3.
The default mapping is:
• Priority 0. 3 is assigned to Q0. This is the lowest priority queue.
• Priority 1, 2 is assigned to Q1.
• Priority 4, 5 is assigned to Q2.
• Priority 6, 7 is assigned to Q3. This is the highest priority queue.
To map priority to queues:
1. Click QoS > 802.1p User Priority. The
802.1P User Priority Page opens:
