Cisco route Configuring MPLS QoS 举例

284354749

　　This example shows that all packets that contain MPLS experimental value  4 are matched by the traffic>
　　Router(config)# >　　Router(config-cmap)# match mpls experimental 4
　　Router(config-cmap)# exit

　　This example shows that the  value in the MPLS experimental field of  each packet that is matched by  the>　　Router(config)# policy-map  set_experimental_5

　　Router(config-pmap)#>　　Router(config-pmap-c)# set mpls experimental 5
　　Router(config-pmap-c)# exit
　　Router(config-pmap)# exit
　　This example shows that the service policy set_experimental_5 is  attached to an POS output interface:
　　Router(config)#  interface POS6/1
　　Router(config-if)# service-policy output  set_experimental_5
　　Router(config-if)# exit
　　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>
　　Router(config)#>　　Router(config-cmap)# match mpls  experimental 1
　　Router(config-cmap)# exit

　　Router(config)# >　　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)#>　　Router(config-pmap-c)# set mpls  experimental 5
　　Router(config-pmap-c)# shape average 2000000
　　Router(config-pmap-c)# exit

　　Router(config-pmap)#>　　Router(config-pmap-c)# set mpls experimental 3
　　Router(config-pmap-c)# shape average 3000000
　　Router(config-pmap-c)# exit

　　Router(config-pmap)#>　　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
