OID (numeric): 1.3.6.1.4.1.9.9.120.2.0.8
Node type: NOTIFICATION-TYPE

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> '' CISCO-NETWORK-REGISTRAR-MIB::ciscoNetRegAddressConflict snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.120.2.0.8
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]:60676->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (195330820) 22 days, 14:35:08.20 SNMPv2-MIB::snmpTrapOID.0 = OID: CISCO-NETWORK-REGISTRAR-MIB::ciscoNetRegAddressConflict
SNMPv3 example:
snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' CISCO-NETWORK-REGISTRAR-MIB::ciscoNetRegAddressConflict
