Configuring the Extended MAC Entry Resource Mode

Configuring the Extended MAC Entry Resource Mode


You can increase the MAC address table size by changing the MAC entry resource mode.

When the switch transmits heavy traffic, MAC address entries increase accordingly. If the current MAC address table size cannot meet service requirements, service running efficiency is reduced. The switch provides an extended register that you can use to increase the size of the MAC address table, thereby enabling the switch to learn more MAC addresses.


Only the S5720EI, S6720EI and S6720S-EI support this function.


  1. (Optional) Run display resource-mode configuration

    The extended entry resource mode is displayed.

  2. Run system-view

    The system view is displayed.

  3. Run assign resource-mode enhanced-mac slot slot-id

    The extended MAC entry resource mode is configured.


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

Verifying the Configuration

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