PFC is enabled on traffic classes with dot1p 4, 5, 6, and 7 traffic. The traffic classes all use the default PFC pause settings for shared buffer size and pause frames in ingress queue processing in the network-qos policy map. The pclass policy map honors (trusts) all dot1p ingress traffic. The reserved class-trust class map is configured by default. Trust does not modify ingress values in output flows.

PFC configuration (interface) Apply the service policies with dot1p trust and PFC configurations to an interface. OS10(config)# interface ethernet 1/1/53 OS10(conf-if-eth1/1/53)# no shutdown OS10(conf-if-eth1/1/53)# service-policy input type network-qos test OS10(conf-if-eth1/1/53)# service-policy input type qos pclass OS10(conf-if-eth1/1/53)# priority-flow-control mode on OS10(conf-if-eth1/1/53)# end 4. ETS configuration (global) A trust dot1p-map assigns dot1p 0, 1, 2, and 3 traffic to qos-group 0, and dot1p 4, 5, 6, and 7 traffic to qos-group 1. A qos-map traffic-class map assigns the traffic class in qos-group 0 to queue 0, and qos-group 1 traffic to queue 1. A queuing policy map assigns 30% of interface bandwidth to queue 0, and 70% of bandwidth to queue 1. The pclass policy map applies trust to all dot1p ingress traffic. Trust does not modify ingress dot1p values in output flows. The reserved class-trust class map is configured by default.
