You can designate a device as a trap receiver as explained in "Adding or
Updating a Trap Receiver" in the "SNMP Configuration" section of Chapter 3.
This receiver device will get the following information from the specified traps.
Table 5-1 Security Traps
The following subsections describe each of the three security options in detail.
Duplicated IP Detection/Trap
These two security measures allow you to set up detection and the sending of a
trap (alert) for the use of a single IP address by two stations. If you enable
Duplicated IP detection, the switch starts monitoring the broadcast ARP
(Address Resolution Protocol) traffic from all of its ports, to detect duplicated
IP address conditions. If you enable detection and the sending of a trap, then
the designated trap receiver will get an alert each time a duplicated IP address is
used on the system.
◆ Note: In order to send Duplicated IP traps, Duplicated IP
detection must be enabled.
