Configuring the Extended MAC Entry Resource Mode

Configuring the Extended MAC Entry Resource Mode


When the switch transmits heavy traffic, MAC address entries increase accordingly. However, the switch has a limited space for MAC address entries. If the MAC address table size cannot meet service requirements, service running efficiency is reduced. The LPUs of the switch provide the extended entry space register. You can configure an extended MAC entry resource mode to increase the MAC address table size.


  1. (Optional) Run:

    display resource-assign configuration

    The extended entry resource mode is displayed.

  2. Run:


    The system view is displayed.

  3. Run:

    assign resource-mode slot slot-id mode enhanced-mac

    The extended MAC entry resource mode is configured.


    After the extended MAC entry resource mode is configured, you must restart the LPU of the switch to make the configuration take effect.

Checking the Configuration

Run the display resource-assign configuration command to check the configured and current extended entry resource modes.
