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 Action Purpose
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
