2. PFC conguration (global)
PFC is enabled on trac classes with dot1p 4, 5, 6, and 7 trac. All the trac classes use the default PFC pause settings for shared buer
size and pause frames in ingress queue processing in the network-qos policy map. The pclass policy map honors (trusts) all dot1p ingress
trac. The reserved class-trust class map is congured by default. Trust does not modify ingress values in output ows.
OS10(config)# class-map type network-qos test4
OS10(config-cmap-nqos)# match qos-group 4
OS10(config-cmap-nqos)# exit
OS10(config)# class-map type network-qos test5

OS10(config-cmap-nqos)# exit
OS10(config)# class-map type network-qos test6
OS10(config-cmap-nqos)# match qos-group 6
OS10(config-cmap-nqos)# exit
OS10(config)# class-map type network-qos test7
OS10(config-cmap-nqos)# match qos-group 7
OS10(config-cmap-nqos)# exit
OS10(config)# policy-map type network-qos test
OS10(config-pmap-network-qos)# class test4

OS10(config-pmap-c-nqos)# exit
OS10(config-pmap-network-qos)# class test5

OS10(config-pmap-network-qos)# exit
OS10(config)# system qos
OS10(config-sys-qos)# trust-map dscp default
3. PFC conguration (interface)
Apply the service policies with dot1p trust and PFC congurations 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 conguration (global)
A trust dot1p-map assigns dot1p 0, 1, 2, and 3 trac to qos-group 0, and dot1p 4, 5, 6, and 7 trac to qos-group 1. A qos-map traffic-
class map assigns the trac class in qos-group 0 to queue 0, and qos-group 1 trac 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 trac. Trust does not modify ingress dot1p values in output ows. The reserved
class-trust class map is congured by default.
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
