Important! For any traps (alerts) to be sent, one or more devices must be designated as trap receivers. See “SNMP Configuration” in Chapter 3.

4.2.1 Duplicated IP Detection and Trap

The duplicated IP detection and duplicated IP trap security measures allow the user to monitor the use of a single IP address by two stations.

If duplicated IP detection is enabled, the switch starts monitoring the broadcast Address Resolution Protocol (ARP) traffic from all of its ports, to detect duplicated IP address conditions. When duplicate IP addresses are used on the system, the MAC addresses of both stations and the ports they accessed are logged.

If both duplicated IP detection and duplicated IP trap are enabled, 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.

Enabling and Disabling Duplicated IP Detection

To enable or disable detection of duplicated IP addresses:

1.From the Configuration Menu, type t to access the Security Management Menu.

2.Type d to toggle duplicated IP detection.
