cigDhcpClientsConflictDetectionTrap
Module: CIG-CLIENTS-MIB
OID (symbolic): CIG-CLIENTS-MIB::cigDhcpClientsConflictDetectionTrap
OID (numeric): 1.3.6.1.4.1.6889.2.1.17.1.0.1

Description: DHCP IP address conflict detection. This trap is based on: The Client Decline Packets after the client sent gratuitous Arp and get response which implies that another station use this IP address.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' CIG-CLIENTS-MIB::cigDhcpClientsConflictDetectionTrap snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.6889.2.1.17.1.0.1
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
zoo11-linux.zoo [UDP: [192.168.30.111]:61032->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (356107368) 41 days, 5:11:13.68 SNMPv2-MIB::snmpTrapOID.0 = OID: CIG-CLIENTS-MIB::cigDhcpClientsConflictDetectionTrap
