Impact on the System

This alarm indicates that an IP address conflict occurred. If the IP address conflict is not eliminated timely, route flapping may occur and services may be interrupted.

Possible Causes

The device could find the source IP address carried in a non-gratuitous ARP packet among its local ARP entries, but could not find the source MAC address carried in that packet among its local ARP entries. The interface receives an ARP probe packet, whose destination IP address conflicts with the local interface address.

Procedure

1. Check whether there is any IP address conflict on the live network.
