Configuring the Switch to Discard Packets with an All-0 MAC Address

Configuring the Switch to Discard Packets with an All-0 MAC Address

Context

You can configure the switch to discard packets with an all-0 source or destination MAC address.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run drop illegal-mac enable

    The switch is enabled to discard packets with an all-0 MAC address.

    By default, the switch does not discard packets with an all-0 MAC address.

  3. (Optional) Run drop illegal-mac alarm

    The switch is configured to send an alarm to the NMS when receiving packets with an all-0 MAC address.

    By default, the switch does not send an alarm when receiving packets with an all-0 MAC address.

    NOTE:

    The drop illegal-mac alarm command allows the switch to generate one alarm. You must reconfigure the drop illegal-mac alarm command if more than one alarm is required.

Verifying the Configuration

Run the display current-configuration command to check whether the switch is enabled to discard packets with an all-0 MAC address.
