2. PFC configuration (global)
PFC is enabled on traffic classes with dot1p 4, 5, 6, and 7 traffic. All the traffic classes use the default PFC pause settings
for shared buffer size and pause frames in ingress queue processing in the network-qos policy map. The trust-map dot1p
default honors (trusts) all dot1p ingress traffic.

3. 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)# trust-map dot1p default
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.
OS10(config)# trust dot1p-map tmap1
OS10(config-tmap-dot1p-map)# qos-group 0 dot1p 0-3
OS10(config-tmap-dot1p-map)# qos-group 1 dot1p 4-7
OS10(config-tmap-dot1p-map)# exit
OS10(config)# qos-map traffic-class tmap2
OS10(config-qos-map)# queue 0 qos-group 0
OS10(config-qos-map)# queue 1 qos-group 1
OS10(config-qos-map)# exit
OS10(config)# class-map type queuing cmap1
OS10(config-cmap-queuing)# match queue 0
OS10(config-cmap-queuing)# exit
OS10(config)# class-map type queuing cmap2
