Chapter 42 Configuring PFC QoS

Configuring PFC QoS

Note When you apply both ingress policing and egress policing to the same traffic, both the input policy and the output policy must either mark down traffic or drop traffic. PFC QoS does not support ingress markdown with egress drop or ingress drop with egress markdown.

This example shows how to create a named aggregate policer with a 1-Mbps rate limit and a 10-MB burst size that transmits conforming traffic and marks down out-of-profile traffic:

Router(config)# mls qos aggregate-policer aggr-1 1000000 10000000 conform-action transmit

exceed-action policed-dscp-transmit

Router(config)# end

Router#

This example shows how to verify the configuration:

Router# show mls qos aggregate-policer aggr-1

ag1 1000000 1000000 conform-action transmit exceed-action policed-dscp-transmit AgId=0 [pol4]

Router#

The output displays the following:

•The AgId parameter displays the hardware policer ID.

•The policy maps that use the policer are listed in the square brackets ([]).
