Chapter 42 Configuring PFC QoS

Configuring PFC QoS

•Aggregate policing works independently on each DFC-equipped switching module and independently on the PFC, which supports any non-DFC-equipped switching modules. Aggregate policing does not combine flow statistics from different DFC-equipped switching modules. You can display aggregate policing statistics for each DFC-equipped switching module and for the PFC and any non-DFC-equipped switching modules supported by the PFC.

•Each PFC or DFC polices independently, which might affect QoS features being applied to traffic that is distributed across the PFC and any DFCs. Examples of these QoS feature are:

–Policers applied to a port channel interface.

–Policers applied to a switched virtual interface.

–Egress policers applied to either a Layer 3 interface or an SVI. Note that PFC QoS performs egress policing decisions at the ingress interface, on the PFC or ingress DFC.

Policers affected by this restriction deliver an aggregate rate that is the sum of all the independent policing rates.

•With a PFC3, 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 attach the policy map named pmap1 to Fast Ethernet port 5/36:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)# interface fastethernet 5/36

Router(config-if)#service-policy input pmap1

Router(config-if)# end

This example shows how to verify the configuration:

Router# show policy-map interface fastethernet 5/36
