Duplicated IP Detection and Trap
The duplicated IP detection and duplicated IP trap security measures allow
you to monitor the use of a single IP address by two stations.
If you enable duplicated IP detection, the switch starts monitoring the
broadcast Address Resolution Protocol (ARP) traffic from all of its ports, to
detect duplicated IP address conditions. When duplicate IPs are used on the
system, the MAC addresses of both stations and the ports they accessed are
logged.
If you enable both duplicated IP detection and duplicated IP trap, the
designated trap receiver gets an alert each time a duplicated IP address is
used on the system. In order to send duplicated IP traps, duplicated IP
detection must be enabled.
By default, duplicated IP detection and trapping are enabled.
