Information About MQC Policy Map on Configured VC Range ATM

The MQC Policy Map Support on Configured VC Range feature simplifies the configuration of ATM VC ranges by allowing you to attach policy maps on a range of ATM VCs or on a specific VC within a range of VCs.

How to Configure MQC Policy Map on Configured VC Range ATM

Attaching QoS Policies to an ATM PVC Range

Use the following configuration steps to attach a QoS policy to a range of ATM PVCs.

SUMMARY STEPS

    1.    enable

    2.    configure terminal

    3.    interface atm slot/subslot/port[.subinterface] [multipoint | point-to-point]

    4.    range [range-name] pvc start-vpi/start-vci end-vpi/end-vci

    5.    service-policy input output policy-map-name

    6.    end


DETAILED STEPS
     Command or ActionPurpose
    Step 1 enable


    Example:
    Router> enable
     

    Enables privileged EXEC mode.

    • Enter your password if prompted.
     
    Step 2 configure terminal


    Example:
    Router# configure terminal
     

    Enters global configuration mode.

     
    Step 3 interface atm slot/subslot/port[.subinterface] [multipoint | point-to-point]

    Example:
    Router(config)# interface atm 1/0.1
     

    Specifies the ATM interface and enters interface configuration mode.

     
    Step 4 range [range-name] pvc start-vpi/start-vci end-vpi/end-vci

    Example:
    Router(config-if)# range pvc 101/304 200/400
     

    Defines a range of ATM permanent virtual circuits (PVCs) and enters ATM range configuration mode.

    • (Optional) range-name is the name of the range. The range-name can be a maximum of 15 characters.
    • start-vpi/ specifies the beginning value for a range of virtual path identifiers (VPIs). The slash is required. If you do not provide a VPI value or the slash, the default value of 0 is used. Valid values for VPI are from 0 to 255.
    • start-vci specifies the beginning value for a range of virtual channel identifiers (VCIs). Valid values are from 32 to 65535.
    • end-vpi/ specifies the end value for a range of virtual path identifiers (VPIs). The slash is required. If you do not provide a VPI value or the slash, the start-vpi value is used by default. Valid values for VPI are from 0 to 255.
    • end-vci specifies the end value for a range of virtual channel identifiers (VCIs). Valid values are from 32 to 65535.
     
    Step 5 service-policy input output policy-map-name


    Example:
    Router(config-if-atm-range)# service-policy output Downstream_Traffic
     

    Attaches the service policy you specify to the specified ATM PVC range and enters ATM PVC range configuration mode.

    • input indicates to apply the service policy to the inbound traffic on the interface.
    • output indicates to apply the service policy to the outbound traffic on the interface.
    Note   

    For QoS policies containing the bandwidth, priority, random-detect, queue-limit, and shape commands, you must specify the output keyword. The router ignores these commands when you use them with the input keyword.

    • policy-map-name is the name of the policy map you want to attach to the subinterface.
    Note   

    The router applies the service policy to only the PVCs within the PVC range.

     
    Step 6 end


    Example:
    Router(config-if-atm-range)# end
     

    Exits ATM PVC range configuration mode and returns to privileged EXEC mode.

     

    Attaching QoS Policies to an Individual PVC Within an ATM PVC Range

    Use the following configuration task to attach a QoS policy to an individual PVC within a range of ATM PVCs.

    SUMMARY STEPS

      1.    enable

      2.    configure terminal

      3.    interface atm slot/subslot/port[.subinterface] [multipoint | point-to-point]

      4.    range [range-name] pvc start-vpi/start-vci end-vpi/end-vci

      5.    pvc-in-range [pvc-name] vpi/vci

      6.    service-policy input output policy-map-name

      7.    end


    DETAILED STEPS

      Enters global configuration mode.

       
      Step 3 interface atm slot/subslot/port[.subinterface] [multipoint | point-to-point]

      Example:
      Router(config)# interface atm 1/0
       

      Specifies the ATM interface and enters interface configuration mode.

       
      Step 4 range [range-name] pvc start-vpi/start-vci end-vpi/end-vci

      Example:
      Router(config-if)# range pvc 101/304 200/400
       

      Defines a range of ATM permanent virtual circuits (PVCs) and enters ATM range configuration mode.

      • (Optional) range-name is the name of the range. The range-name can be a maximum of 15 characters.

      Configuration Examples for MQC Policy Map on Configured VC Range ATM

      Attaching QoS Service Policies to an ATM PVC Range Example

      The following example configuration shows how to attach policy maps to a range of ATM PVCs. In the example, the service policy named voice is attached to the range of ATM PVCs 1/32 to 1/34. The router applies the service policy to all of the PVCs within the PVC range.

      Router(config)# interface atm 2/0/0
      Router(config-if)# range pvc 1/32 1/34
      Router(config-if-atm-range)# service-policy input voice

      Attaching QoS Service Policies to an Individual PVC Within an ATM PVC Range Example

      The following example configuration shows how to attach policy maps to a specific PVC within a PVC range. In the example, the service policy named data is attached to PVC 1/33 within the PVC range 1/32 to 1/34. The router applies the service policy to only PVC 1/33.

      Router(config)# interface atm 2/0/0
      Router(config-if)# range pvc 1/32 1/34
      Router(config-if-atm-range)# service-policy input voice
      Router(config-if-atm-range)# pvc-in-range 1/33
      Router(config-if-atm-range-vc)# service-policy input data
