Usage Guidelines
You should use the priority queue only for traffic that needs to be expedited (for example, voice traffic,
which needs minimum delay and jitter).
The priority queue is guaranteed part of the bandwidth on the internal ring, which reduces the delay and
jitter under heavy network traffic on an oversubscribed ring (when there is more traffic than the
backplane can carry, and the queues are full and dropping frames).
Shaped round robin (SRR) services the priority queue for its configured weight as specified by the
bandwidth keyword in the mls qos srr-queue input priority-queue queue-id bandwidth weight global
configuration command. Then SRR shares the remaining bandwidth with both ingress queues and
services them as specified by the weights configured with the mls qos srr-queue input bandwidth
weight1 weight2 global configuration command.
To disable priority queueing, set the bandwidth weight to 0, for example, mls qos srr-queue input
priority-queue queue-id bandwidth 0.
