Because the police commands executed in policy map configuration mode do not allow remarking of
qos-groups for traffic flows that exceed defined rate limits, AutoQos-4.0-Scavenger-Queue must be
configured to match either qos- group 7 or dscp af11. When the auto qos classify police command has
been executed, traffic flows that violate the defined rate limit are remarked to cs1 but retain their original
qos-group classifica tion beca use qos-gr oups cannot be rema rked as an e xceed ac tion. However, be cause
AutoQos-4.0-Scavenge r-Queue is defined before all other queues in the outpu t policy map, remarked
packets will fall into it, despite retaining their original qos-group labels.
