This trap is caused by the detection of a duplicate IP address. It means that there are 2 or more stations using the same IP address. The first parameter is the IP Address which is duplicated. The next three parameters are the MAC address, VLAN ID, Group number and port number of the switch from where the original IP-MAC Address binding was detected. The remaining three parameters are the MAC address, VLAN ID, Group number and Port number of the switch from where the spoofed IP-MAC Address binding was detected.
