Create classes fl1 and fl2, specify the respective access control lists, configure labelling:
esr(config)# class-map fl1
esr(config-class-map)# set dscp 38
esr(config-class-map)# match access-group fl1
esr(config-class-map)# exit
esr(config)# class-map fl2
esr(config-class-map)# set dscp 42
esr(config-class-map)# match access-group fl2
esr(config-class-map)# exit
Create policy and define general bandwidth limits:
esr(config)# policy-map fl
esr(config-policy-map)# shape average 250000
Map class to policy, configure bandwidth limit and exit:
esr(config-policy-map)# class fl1
esr(config-class-policy-map)# shape average 40000
esr(config-class-policy-map)# exit
esr(config-policy-map)# class fl2
esr(config-class-policy-map)# shape average 60000
esr(config-class-policy-map)# exit
To set the bandwidth limit as a percentage, use the shape average percent command.
For the rest of traffic, configure a class with SFQ mode:
esr(config-policy-map)# class class-default
esr(config-class-policy-map)# mode sfq
esr(config-class-policy-map)# fair-queue 800
esr(config-class-policy-map)# exit
esr(config-policy-map)# exit
Enable QoS on the interfaces, policy on gi 1/0/19 interface ingress for classification purposes and gi1/0/20
egress for applying restrictions and SFQ mode for default class:
esr(config)# interface gigabitethernet 1/0/19
esr(config-if-gi)# qos enable
esr(config-if-gi)# service-policy input fl
esr(config-if-gi)# exit
esr(config)# interface gigabitethernet 1/0/20
esr(config-if-gi)# qos enable
esr(config-if-gi)# service-policy output fl
esr(config-if-gi)# exit
To view the statistics, use the following command:
esr# do show qos policy statistics gigabitethernet 1/0/20
