We're using low-latency queuing (LLQ), SO why does show interface tell us something different? LLQ is tech- nically class-based weighted fair queuing (CBWFQ) with a strict priority queue. Be- cause CBWFQ is a type of weighted fair queuing, the router simply reports the queuing strategy as weighted fair. Notice that show interface does not show the individual queues that we specified in the policy map. To show their statuses, we need to use the show policy-map interface Monitoring QoS interface# command. This command produces a lot of output, and the more queues you have configured, the longer the output will be: R1#sho policy-map interface s0/1 Serial0/1 Service-policy output: WAN Class-map: Voice-RTP (match-any) 19211963 packets, 3918472220 bytes 5 minute offered
