Chapter 32 Configuring PFC QoS
Configuring PFC QoS
• (Optional—Not supported with the flow keyword) For traffic that exceeds the PIR, you can specify
a violate action as follows:
–
For marking without policing, you can enter the transmit keyword to transmit all matched
out-of-profile traffic.
–
The default violate action is equal to the exceed action.
–
You can enter the policed-dscp-transmit keyword to cause all matched out-of-profile traffic to
be marked down as specified in the markdown map (see the “Configuring DSCP Markdown
Val ue s” section on page 32-68).
The violate-action keyword is not supported with the PFC1, but the keyword can be entered with
the PFC1 if the parameters match the exceed-action parameters.
Note Aggregate policing works independently on each DFC-equipped switching module and independently
on the PFC2, 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 PFC2 and any
non-DFC-equipped switching modules supported by the PFC2.
This example shows how to create a policy map named max-pol-ipp5 that uses the class-map named
ipp5, which is configured to trust received IP precedence values and is configured with a
maximum-capacity aggregate policer and with a microflow policer:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# policy-map max-pol-ipp5
Router(config-pmap)# class ipp5
Router(config-pmap-c)# trust ip-precedence
Router(config-pmap-c)# police 2000000000 2000000 conform-action set-prec-transmit 6
exceed-action policed-dscp-transmit
Router(config-pmap-c)# police flow 10000000 10000 conform-action set-prec-transmit 6
exceed-action policed-dscp-transmit
Router(config-pmap-c)# end
Verifying Policy Map Configuration
To verify policy map configuration, perform this task:
Command Purpose
Step 1
Router(config-pmap-c)# end
Exits policy map class configuration mode.
Note Enter additional class commands to create
additional classes in the policy map.
Step 2
Router# show policy-map policy_name
Verifies the configuration.
