QoS Policy Configuration Examples
12-28 Configuring Quality of Service
XSR(config)#map-class frame-relay VoIP
XSR(config-map-class<VoIP>)#frame-relay cir out 256000
XSR(config-map-class<VoIP>)#frame-relay bc out 25600
XSR(config-map-class<VoIP>)#frame-relay be out 0
XSR(config-map-class<VoIP>)#service-policy output QoS-Policy
XSR(config-map-class<VoIP>)#frame-relay fragment 300
QoS with VLAN Policy
The following example configures QoS on a VLAN interface. First, add the class map cos5To7 with
the matching CoS criterion 5 6 7. Then, create the traffic policy setCosTo4, associate it with the class
map, set the minimum bandwidth guarantee to 50 percent, and specify the output VLAN header
priority to 4. Finally, configure VLAN ID 1200 on GigabitEthernet sub-interface 2.1.
XSR(config)#class-map match-any Cos5To7
XSR(config-cmap<Cos5to7>)#match cos 5 6 7
XSR(config-cmap<Cos5to7>)#exit
XSR(config)#policy-map setCosTo4
XSR(config-pmap<setCosTo4>)#class cos5To7
XSR(config-pmap-c<Cos5to7>)#bandwidth percent 50
XSR(config-pmap-c<Cos5to7>)#set cos 4
XSR(config-pmap-c<Cos5to7>)#exit
XSR(config)#interface gigabitethernet 2.1
XSR(config-if<G2.1>)#vlan 1200
XSR(config-if<G2.1>)#ip address 192.168.33.44 255.255.255.0
XSR(config-if<G2.1>)#service-policy output setCosTo4
XSR(config-if<G2.1>)#no shutdown
Input and Output QoS Policy
The following example displays how the same policy map may be applied for input and output.
With MLPPP, it is used for input QoS and on the Ethernet interface it is used for output QoS
policy. Shaping, RED and bandwidth features take no effect on MLPPP.
XSR(config)#class-map A
XSR(config-cmap<A>)#match ip DSCP 32
XSR(config-cmap<A>)#match access-group 101
XSR(config-cmap<A>)#exit
XSR(config)#policy-map InOut
XSR(config-pmap<InOut>)#class A
XSR(config-pmap-c<A>)#bandwidth per 20
XSR(config-pmap-c<A>)#shape 100000
XSR(config-pmap-c<A>)#random-detect 10 20 10
XSR(config-pmap-c<A>)#exit
XSR(config-pmap<InOut>)#class class-default
XSR(config-pmap-c<class-default>)#police 50000 2000
XSR(config-pmap-c<class-default>)#exit
XSR(config-pmap<InOut>)#exit
