Configuring ACL-based Packet Priority Re-marking

Configuring ACL-based Packet Priority Re-marking

You can configure ACL-based packet priority re-marking on interfaces to re-mark priorities on packets matching ACL rules, so as to provide differentiated services.

Pre-configuration Tasks

Before configuring ACL-based packet priority re-marking, complete the following tasks:
  • Configure link layer attributes of interfaces to ensure that the interfaces work properly.

  • Configure IP addresses and routing protocols for interfaces to ensure connectivity.

  • Configure ACLs.

NOTE:
The AD9431DN-24X does not support ACL-based priority re-marking for wireless packets in the VLANIF interface view.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    interface interface-type interface-number

    The interface view is displayed.

  3. Run:

    traffic-remark { inbound | outbound }  acl { acl-number | name acl-name } { 8021p 8021p-value | dscp dscp-value }

    ACL-based packet re-marking is configured

    By default, ACL-based priority re-marking is not configured on an interface.

    The traffic-remark command can reference a numbered ACL that is not configured. You can configure the referenced ACL after running this command.

    A maximum of eight ACLs can be configured for re-marking packet priorities in the same direction. The ACLs take effect following the configuration sequence. To improve ACL match efficiency, you are advised to configure rules with a high match probability first. When configuring each ACL, set a rule ID with a high match probability to a smaller value to reduce the number of matching times, reducing resource waste. To change the packet priority re-marking sequence, delete the related configuration and run the traffic-remark command to reconfigure ACL-based priority re-marking.

Checking the Configuration

  • Run the display traffic-remark applied-record command to check applications of ACL-based packet priority re-marking.
