Configuring IP Address Conflict Detection

Background

IP address conflict detection allows a device to send ARP packets to detect IP address conflicts on a network.

If devices on a network have the same IP addresses, CPU usage becomes excessively high and routes on the devices flap frequently. This greatly affects user services and may result in service interruption. Configuring IP address conflict detection facilitates IP address management and allows a device to quickly locate the conflicting IP address. After detecting an IP address conflict, the device records a log.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run arp ip-conflict-detect enable

    IP address conflict detection is enabled.

    By default, IP address conflict detection is disabled.

Follow-up Procedure

Run the display arp ip-conflict track command in any view to check the records about the IP address conflicts detected by the device.
