auto qos srnd4
B. This template for egress queue classes (along with the SRND4 output policy) allocates eight queues.
This template is required by all SRND4 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 the police commands executed in policy map configuration mode do not allow the re-marking
of qos-groups for traffic flows that exceed defined rate limits, you should configure
AutoQos-4.0-Scavenger-Queue to match either qos-group 7 or dscp af11. When you enter the auto qos
classify police command, traffic flows that violate the defined rate limit are remarked to cs1 but retain
their original qos-group classificatio because such groups cannot be re-marked as an exceed action.
However, because AutoQos-4.0-Scavenger-Queue is defined before all other queues in the output policy
map, re-marked packets fall into it, despite retaining their original qos-group labels.
