Configuring the Resource Mode of the Extended ACL Entry Space

Configuring the Resource Mode of the Extended ACL Entry Space


A core device processes a large number of services and therefore maintains many ACL entries. However, the number of entries supported by the device is limited. If these entries cannot meet service requirements, the service processing efficiency degrades. The device provides a register for expanding entry spaces. You can configure the resource allocation mode for the extended entry space to expand space for ACL entries.


Only the S5720HI supports this command.


  1. (Optional) Run display system resource-template [ slot slot-id ]

    The system resource template information is displayed.

  2. Run system-view

    The system view is displayed.

  3. Run assign resource-template acl-mode { dual-ipv4-ipv6 | ipv4 | l2 | l2-ipv4 | l2-ipv6 } [ slot slot-id ]

    The ACL resource allocation mode is configured.

    By default, the ACL resource allocation mode is dual-ipv4-ipv6.


    After configuring the ACL resource allocation mode, save the configuration, and restart the device for the configuration to take effect.

    l2-ipv4 32K 32K 0 0 32K 32K
    l2-ipv6 0 0 16K 16K 16K 16K
