auto qos classify police
AutoQos-4.0-Scavenger-Queue must be configured to match either qos-group 7 or dscp af11 to
accomodate for the fact that police commands executed in policy map configuration mode do not allow
the remarking of qos-groups for traffic flows that exceed defined rate limits. After entering the auto qos
classify police command, traffic flows that violate the defined rate limit are remarked to cs1 but retain
their original qos-group classification because qos-groups cannot be remarked as an exceed action.
However, because AutoQos-4.0-Scavenger-Queue is defined before all other queues in the output policy
map, remarked packets fall into it, despite retaining their original qos-group labels.
