Configuring MQC-based VLAN Mapping

Configuring MQC-based VLAN Mapping

Context

MQC-based VLAN mapping uses a traffic classifier to classify packets based on VLAN IDs, associates the traffic classifier with a traffic behavior defining VLAN mapping so that the device can re-mark the VLAN ID in packets matching the traffic classifier.

NOTE:

The CE6870EI and CE6875EI do not support this function.

Procedure

  1. Configure a traffic classifier.
    1. Run system-view

      The system view is displayed.

    2. Run traffic classifier classifier-name [ type { and | or } ]

      A traffic classifier is created and the traffic classifier view is displayed, or the view of an existing traffic classifier is displayed.

      and is the logical operator between the rules in a traffic classifier, which means that:
      • If a traffic classifier contains ACL rules, packets match the traffic classifier only if they match one ACL rule and all the non-ACL rules.

      • If a traffic classifier does not contain any ACL rules, packets match the traffic classifier only if they match all the rules in the classifier.

      The logical operator or means that packets match a traffic classifier if they match one or more rules in the classifier.

      By default, the relationship between rules in a traffic classifier is or.

    3. Run if-match

      Matching rules are defined for the traffic classifier.

      For details about matching rules in a traffic classifier, see "Configuring a Traffic Classifier" in "MQC Configuration" of the CloudEngine 8800, 7800, 6800, and 5800 Series Switches Configuration Guide - QoS Configuration Guide.

    4. Run commit

      The configuration is committed.

    5. Run quit

      Exit from the traffic behavior view.

  2. Configure a traffic behavior.
    1. Run traffic behavior behavior-name

      A traffic behavior is created and the traffic behavior view is displayed, or the view of an existing traffic behavior is displayed.

    2. Run vlan-mapping vlan vlan-id

      The interface is configured to replace the outer VLAN tag in packets.

    3. (Optional) Run vlan-mapping inner-vlan inner-vlan-id

      The interface is configured to replace the inner VLAN tag in packets.

    4. Run commit

      The configuration is committed.

    5. Run quit

      Exit from the traffic behavior view.

    6. Run quit

      Exit from the system view.

  3. Configure a traffic policy.
    1. Run system-view

      The system view is displayed.

    2. Run traffic policy policy-name

      A traffic policy is created and the traffic policy view is displayed, or the view of an existing traffic policy is displayed.

    3. Run classifier classifier-name behavior behavior-name [ precedence precedence-value ]

      A traffic behavior is bound to a traffic classifier in the traffic policy.

    4. Run commit

      The configuration is committed.

    5. Run quit

      Exit from the traffic policy view.

    6. Run quit

      Exit from the system view.

  4. Apply the traffic policy.
    NOTE:

    For details about the configuration guidelines of applying traffic policies in different views on the CE switches excluding CE6870EI and CE6875EI, see Licensing Requirements and Limitations for MQC (CE Switches Excluding CE6870EI and CE6875EI).

    If a traffic policy needs to be applied to multiple VLANs and interfaces or multiple traffic classifiers for matching packets from different source IP addresses need to be bound to the same traffic policy, you are advised to add these VLANs, source IP addresses, and interfaces to the same QoS group and apply the traffic policy to the QoS group.

    • Applying a traffic policy to an interface
      1. Run system-view

        The system view is displayed.

      2. Run interface interface-type interface-number

        The interface view is displayed.

      3. Run traffic-policy policy-name { inbound | outbound }

        A traffic policy is applied to the interface.

      4. Run commit

        The configuration is committed.

    • Applying a traffic policy to a VLAN
      1. Run system-view

        The system view is displayed.

      2. Run vlan vlan-id

        The VLAN view is displayed.

      3. Run traffic-policy policy-name { inbound | outbound }

        A traffic policy is applied to the VLAN.

        The system applies traffic policing to the packets that belong to the VLAN and match traffic classification rules in the inbound or outbound direction.

      4. Run commit

        The configuration is committed.

    • Applying a traffic policy to the system
      1. Run system-view

        The system view is displayed.

      2. Run traffic-policy policy-name global [ slot slot-id ] { inbound | outbound }

        A traffic policy is applied to the system.

      3. Run commit

        The configuration is committed.

    • Applying a traffic policy to a QoS group
      1. Run system-view

        The system view is displayed.

      2. Run qos group group-name

        The QoS group view is displayed.

      3. Run the following commands as required:
        • Run the group-member interface { interface-type interface-number1 [ to interface-type interface-number2 ] } &<1-8> command to add interfaces to the QoS group.

        • Run the group-member vlan { vlan-id1 [ to vlan-id2 ] } &<1-8> command to add VLANs to the QoS group.

        • Run the group-member ip source ip-address { mask | mask-length } command to add source IP addresses to the QoS group.

      4. Run traffic-policy policy-name inbound

        A traffic policy is applied to the QoS group.

      5. Run commit

        The configuration is committed.

      1. Run system-view

        The system view is displayed.

      2. Run bridge-domain bd-id

        The BD view is displayed.

      3. Run traffic-policy policy-name outbound

        A traffic policy is applied to the BD.

      4. Run commit

        The configuration is committed.

Verifying the Configuration

  • Run the display traffic classifier [ classifier-name ] command to check the traffic classifier configuration.
  • Run the display traffic behavior [ behavior-name ] command to check the traffic behavior configuration on the device.
  • Run the display traffic policy [ policy-name [ classifier classifier-name ] ] command to check the traffic policy configuration.

  • Run the display traffic-policy applied-record [ policy-name ] [ global [ slot slot-id ] | interface interface-type interface-number | vlan vlan-id | vpn-instance vpn-instance-name | qos group group-id | bridge-domain bd-id ] [ inbound | outbound ] command to check the application records of a specified traffic policy.

    NOTE:
    • The CE6810LI does not support the vpn-instance vpn-instance-name parameter.
    • The CE5810EI, CE5850EI, CE5850HI, CE5855EI, CE6810LI, CE6810EI, and CE6850EI do not support the bridge-domain bd-id command.
  • Run the display system tcam fail-record [ slot slot-id ] command to display TCAM delivery failures.
  • Run the display system tcam service brief [ slot slot-id ] command to display the group index and rule count occupied by different services.
  • Run the display system tcam service { cpcar slot slot-id | service-name slot slot-id [ chip chip-id ] } command to display IDs of entries delivered by services on the specified chip or in the specified slot.
  • Run one of the following commands to display data of a traffic policy that has been applied:
    • display system tcam service traffic-policy { global | vlan vlan-id | interface interface-type interface-number | vpn-instance vpn-instance-name | qos group group-id | bridge-domain bd-id } policy-name { inbound | outbound } [ slot slot-id [ chip chip-id ] ]
      NOTE:

      The CE6810LI does not support the vpn-instance vpn-instance-name parameter.

      The CE5810EI, CE5850EI, CE5850HI, CE5855EI, CE6810LI, CE6810EI, and CE6850EI do not support the bridge-domain bd-id command.

    • display system tcam service traffic-policy slot slot-id policy-name { inbound | outbound } [ chip chip-id ]
  • (For the CE6870EI and CE6875EI) Run the display system tcam match-rules slot slot-id [ [ ingress | egress | group group-id ] | [ chip chip-id ] ] * command to display matched entries.
