Step 6. Configure the minimum guaranteed bandwidth for a queue. Command qos bandwidth queue queue-id min bandwidth-value Remarks Optional. 64 kbps for each queue by default. NOTE: To guarantee successful WFQ configuration, make sure that the scheduling weight type (byte-count or packet-based) is the same as the WFQ queuing type (byte-count or packet-based) when you configure the scheduling weight for a WFQ queue. Configuration example Network requirements • Configure SP+WFQ queuing on GigabitEthernet 1/0/1, and use packet-based WFQ scheduling weights. • Configure queue 0, queue 1, queue 2, and queue 3 on GigabitEthernet 1/0/1 to be in SP queue scheduling group. • Configure queue 4, queue 5, queue 6, and queue 7 on GigabitEthernet 1/0/1 to use WFQ queuing, with the weight 2, 4, 6, and 8 and the minimum guaranteed bandwidth 128 kbps.
