mls qos srr-queue input bandwidth
This example shows how to assign the ingress bandwidths for the queues in the stack. Queue 1 is the
priority queue with 10 percent of the bandwidth allocated to it. The bandwidth ratio allocated to queues
1 and 2 is 4/(4+4). SRR services queue 1 (the priority queue) first for its configured 10 percent
bandwidth. Then SRR equally shares the remaining 90 percent of the bandwidth between queues 1 and
2 by allocating 45 percent to each queue:
Switch(config)# mls qos srr-queue input priority-queue 1 bandwidth 10
Switch(config)# mls qos srr-queue input bandwidth 4 4
You can verify your settings by entering the show mls qos interface [interface-id] queueing or the show
mls qos input-queue privileged EXEC command.
