On an S series switch, except S1700:
When the IP addresses of two network devices conflict, the CPU usage on the switch becomes high and route flapping will occur on the switch. User services may be interrupted.
To manage IP addresses efficiently and detect IP address conflicts promptly, enable IP address conflict detection. The switch can record logs for IP address conflicts. The configuration procedure is as follows:
1. Run the system-view command to enter the system view.
2. Run the arp ip-conflict-detect enable command to enable IP address conflict detection.
By default, IP address conflict detection is disabled.
3. Run the display arp ip-conflict track command in any view to check IP address conflict records.
