Configuring the Card Forwarding Resource Mode

Configuring the Card Forwarding Resource Mode



Only the CE12800E series switches support the configuration of the card forwarding resource mode.

Services share chip entry resources. When ARP, MAC, or routing entries cannot meet service requirements, change the system resource mode to obtain a larger entry capacity.
  • large-mac: increases the MAC entry capacity. The large-mac mode is applicable to Layer 2 access and transparent transmission scenarios, where a device mainly forwards Layer 2 unicast packets as well as broadcast, unknown unicast, and multicast (BUM) packets. This mode provides a larger MAC entry space and is often used at the access or aggregation layer (with the gateway deployed at the core layer).

  • large-route: increases the routing entry capacity. The large-route mode is applicable to the core layer of a Layer 3 network and enables a device to learn a large number of network segment routes for Layer 3 forwarding.

  • large-arp: increases the ARP entry capacity. The large-arp mode is applicable to the access or aggregation layer with Layer 3 gateway deployed or the core layer of a small-scale network, and is mainly used for Layer 3 forwarding on directly connected network segments.

  • large-acl: increases the ACL entry capacity.

  • standard: This is the default mode.

  • uft-hybrid: allows you to configure two types of entries each to occupy half of UFT resources.


  1. Run system-view

    The system view is displayed.

  2. (Optional) Run display system resource

    The current card forwarding resource mode is displayed.

  3. Configure the system resource mode.

    • (CE12800E that has CEL24XSED-E/CEL48XSED-E/CEL36LQED-E/CEL24LQED-E cards installed) system resource { standard | large-mac | large-route }
    • (CE12800E that has FD-X cards installed) system resource { large-mac | standard | large-arp | large-acl }
    • (CE12800E that has FD-X cards installed) system resource uft-hybrid { acl { arp | mac | route } | arp { acl | mac } | mac { acl | arp | route } | route { acl | mac } }

    By default, the standard system resource mode is used. After changing the system resource mode, restart the device for the modification to take effect.

  4. Run commit

    The configuration is committed.

  5. Run quit

    Exit from the system view.

  6. Run reboot

    The device is restarted to make the configuration take effect.
