The Switch 4210 supports the WRR queue scheduling algorithm and the high 
queue-WRR (HQ-WRR) queue scheduling algorithm. HQ-WRR is implemented 
based on WRR. HQ-WRR selects queue 3 as the high-priority queue from the 
four output queues. If the bandwidth occupied by the four queues exceeds the 
port capability, packets in queue 3 are preferentially transmitted, and the left 
three queues are scheduled using WRR.

The Switch 4210, 5500, and 5500G provide the default 802.1p-to-local
