Information About Match VLAN

QoS Match VLAN

The QoS: Match VLAN feature allows you to classify network traffic on the basis of the Layer 2 virtual local-area network (VLAN) identification number. To classify network traffic based on the VLAN identification number you create a class-map and specify the match criteria using the match vlan command. You then attach the class to a policy-map and use the policy map in a service policy that is attached to an interface.

How to Configure Match VLAN

Classifying Network Traffic per VLAN

To classify network traffic on a per VLAN basis, perform the following task.

SUMMARY STEPS

    1.    enable

    2.    configure terminal

    3.    class-map {match-any | match-all} class-map-name

    4.    match vlan vlan-id-number

    5.    exit

    6.    policy-map policy-map-name

    7.    class class-map-name

    8.    bandwidth percent percent

    9.    exit

    10.    exit

    11.    policy-map policy-map-name

    12.    class class-map-name

    13.    shape {average | peak} cir

    14.    service-policy {input | output} policy-map-name

    15.    exit

    16.    exit

    17.    interface type number [name-tag]

    18.    service-policy {input | output} policy-map-name

    19.    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 class-map {match-any | match-all} class-map-name


    Example:
    Router(config)# class-map match-any Blue_VRF
     

    Creates a class map and enters class map configuration mode.

     
    Step 4 match vlan vlan-id-number


    Example:
    Router(config-cmap)# match vlan 101
     

    Matches traffic on the basis of the range of VLAN identification numbers specified.

     
    Step 5 exit


    Example:
    Router(config-cmap)# exit
     

    Returns to global configuration mode.

     
    Step 6 policy-map policy-map-name


    Example:
    Router(config)# policy-map Shared_QoS
     

    Creates a policy map that can be attached to an interface and enters policy-map configuration mode.

     
    Step 7 class class-map-name


    Example:
    Router(config-pmap)# class Blue_VRF
     

    Specify the name of the class whose policy you want to create and enters policy-map class configuration mode.

     
    Step 8 bandwidth percent percent


    Example:
    Router(config-pmap-c)# bandwidth percent 30
     

    Specifies the bandwidth allocated for a class belonging to a policy map.

     
    Step 9 exit


    Example:
    Router(config-pmap-c)# exit
     

    Returns to policy-map configuration mode.

     
    Step 10 exit


    Example:
    Router(config-pmap)# exit
     

    Returns to global configuration mode.

     
    Step 11 policy-map policy-map-name


    Example:
    Router(config)# policy-map COS-OUT-SHAPED
     

    Creates a policy map that can be attached to an interface and enters policy-map configuration mode.

     
    Step 12 class class-map-name


    Example:
    Router(config-pmap)# class FROM_WAN
     

    Specify the name of the class whose policy you want to create and enters policy-map class configuration mode.

     
    Step 13 shape {average | peak} cir


    Example:
    Router(config-pmap-c)# shape average 9000000000
     
    Specifies the average rate traffic shaping.

    • The Committed information rate (CIR), is specified in bits per second (bps).

     
    Step 14 service-policy {input | output} policy-map-name


    Example:
    Router(config-pmap-c)# service-policy Shared_QoS
     

    Specifies the name of the predefined policy map to be used as a QoS policy.

     
    Step 15 exit


    Example:
    Router(config-pmap-c)# exit
     

    Returns to policy-map configuration mode.

     
    Step 16 exit


    Example:
    Router(config-pmap)# exit
     

    Returns to global configuration mode.

     
    Step 17 interface type number [name-tag]


    Example:
    Router(config)# interface FastEthernet 0/0.1
     

    Configures an interface type and enters interface configuration mode.

    • Enter the interface type and number.

     
    Step 18 service-policy {input | output} policy-map-name


    Example:
    Router(config-if)# service-policy output COS-OUT-SHAPED
     

    Attaches a policy map to an input interface, a virtual circuit (VC), an output interface, or a VC that will be used as the service policy for the interface.

     
    Step 19 end


    Example:
    Router(config-if)# end
     

    (Optional) Exits interface configuration mode and returns to privileged EXEC mode.

     

    Configuration Examples for Match VLAN

    Example: Classifying Network Traffic per VLAN

    The following example shows how to classify network traffic on a VLAN basis. The VLAN classified traffic is applied to the FastEthernet 0/0.1 subinterface. 

    interface FastEthernet0/0.1
service-policy output COS-OUT-SHAPED
policy-map COS-OUT-SHAPED
      class ADMIN
      class FROM_WAN
               shape average 900000000
               service-policy Shared_QoS
policy-map Shared_QoS
      ! description -- Bandwidth sharing between VRF --
      class Blue_VRF
               bandwidth percent 3
class-map match-any Blue_VRF
      ! description -- traffic belonging to the VRF Blue --
      match vlan  101
