QoS - Congestion Question

[BuckWeet]

Question for anyone who can answer this..

Using LLQ (priority command) under a MQC policy provides policing when there is congestion.

My question is, how is congestion determined? What commands are used to show congestion? I've looked and looked on Cisco's website to get a clear definition and am not able to do so..


Thanks in advance..

When you issue the command 'show interface X' in the page of information you see there are two values 'rxload' and 'txload', these are indicators of the current receive and transmit loading levels on the interface (1-255). By default the load-interval is set to 300-seconds so will show the average load over a 5-minute interval. You can decrease or increase this from 30-600 seconds.
I assume internally the router is a bit more clever than this and knows of congenstion immediately, however the counters are averaged out.
