Dell(conf-in-qos-policy-cpuqos)#exit
Dell(conf)#qos-policy-in rate_limit_400k cpu-qos
Dell(conf-in-qos-policy-cpuqos)#rate-police 400 50 peak 600 50
Dell(conf-in-qos-policy-cpuqos)#exit
Dell(conf)#qos-policy-in rate_limit_500k cpu-qos
Dell(conf-in-qos-policy-cpuqos)#rate-police 500 50 peak 1000 50
Dell(conf-in-qos-policy-cpuqos)#exit
Example of Creating a QoS Class Map to Match Protocol Traffic
Dell(conf)#class-map match-any class_ospf cpu-qos
Dell(conf-class-map-cpuqos)#match ip access-group ospf
Dell(conf-class-map-cpuqos)#exit
