Ingress PE Router Configuration In the following example, ip packets with IP PRecedence 1 entering an MPLS network are shaped to 2000000 bits per second and set to MPLS experimental field 5. When IP packets with IP precedence 0 enter the MPLS network, they are shaped to 3000000 bits per second and set to MPLS experimental field 3. When IP packets with any other IP precedence value enter the MPLS network, they are shaped to 5000000 bits per second.
Step 1 Define two traffic classes: Router(config)# class-map gold Router(config-cmap)# match mpls experimental 1 Router(config-cmap)# exit Router(config)# class-map silver Router(config-cmap)# match mpls experimental 0 Router(config-cmap)# exit
Step 2 Define a policy to take different actions Router(config)# policy-map policy1 Router(config-pmap)# class gold Router(config-pmap-c)# set mpls experimental 5 Router(config-pmap-c)# shape average 2000000 Router(config-pmap-c)# exit Router(config-pmap)# class silver Router(config-pmap-c)# set mpls experimental 3 Router(config-pmap-c)# shape average 3000000 Router(config-pmap-c)# exit Router(config-pmap)# class class-default Router(config-pmap-c)# shape average 5000000 Router(config-pmap-c)# exit Router(config-pmap)# exit
Step 3 Apply the policy to the output interface Router(config)# interface GE-WAN7/1 Router(config-if)# service-policy output policy1
Step 4 Verify the QoS configuration: Router# show policy-map interface POS6/2 POS6/2 service-policy outputolicy1 class-map:gold (match-all) 0 packets, 0 bytes 30 second offered rate 0 bps, drop rate 0 bps match:mpls experimental 1 queue size 0, queue limit 500 packets output 0, packet drops 0 tail/random drops 0, no buffer drops 0, other drops 0 set: mpls experimental 5 shape:cir 2000000, Bc 8000, Be 8000 output bytes 0, shape rate 0 bps class-map:silver (match-all) 9521 packets, 9425790 bytes 30 second offered rate 3681000 bps, drop rate 1505000 bps match:mpls experimental 0 queue size 0, queue limit 128 packets output 2845, packet drops 6676 tail/random drops 6676, no buffer drops 0, other drops 0 set: mpls experimental 3 shape:cir 3000000, Bc 12000, Be 12000 output bytes 2816550, shape rate 642000 bps class-map:class-default (match-any) 0 packets, 0 bytes 30 second offered rate 0 bps, drop rate 0 bps match:any 0 packets, 0 bytes 30 second rate 0 bps queue size 0, queue limit 128 packets output 0, packet drops 0 tail/random drops 0, no buffer drops 0, other drops 0 shape:cir 5000000, Bc 20000, Be 20000 output bytes 0, shape rate 0 bps Router#
