auto qos trust

match qos-group 8
match dscp cs1
Because police commands executed in policy map configuration mode do not allow the 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 po lice command
executes, traffic flows that violate the defined rate limit are remarked to cs1 but retain their original
qos-group classifica tion. This is beca use qos -groups c annot be r emarked a s an exce ed action. However,
because AutoQos-4.0-Scavenger-Queue is defined before all other queues in the output policy map,
remarked packets will fall into it, despite retaining their original qos-group labels.
