auto qos video
B. Template for egress queue classes and the srnd4 output policy that uses the egress classes to allocate
eight queues. This template is required by all srnd commands:
class-map match-all AutoQos-4.0-Priority-Queue
match qos-group 32
class-map match-all AutoQos-4.0-Control-Mgmt-Queue
match qos-group 16
class-map match-all AutoQos-4.0-Multimedia-Conf-Queue
match qos-group 34
class-map match-all AutoQos-4.0-Multimedia-Stream-Queue
match qos-group 26
class-map match-all AutoQos-4.0-Trans-Data-Queue
match qos-group 18
class-map match-all AutoQos-4.0-Bulk-Data-Queue
match qos-group 10
class-map match-any AutoQos-4.0-Scavenger-Queue
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 police command has
been executed, 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 will fall into it, despite retaining their original qos-group labels.
