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

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

Context

A faulty network device may send packets with an all-0 source or destination MAC address to the industrial switch router. You can configure the industrial switch router to discard such packets and send an alarm to the network management system (NMS). You can locate the faulty device according to the alarm.

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

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. (Optional) Run:

    drop illegal-mac alarm

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

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

    NOTE:

    The industrial switch router sends only one alarm after receiving packets with an all-0 MAC address. To enable the industrial switch router to send an alarm again after receiving packets with an all-0 MAC address, run the drop illegal-mac alarm command.

Checking the Configuration

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