hpicfDhcpv4ServerDuplicateAddress
Module: HP-ICF-DHCPV4-SERVER-MIB
OID (symbolic): HP-ICF-DHCPV4-SERVER-MIB::hpicfDhcpv4ServerDuplicateAddress
OID (numeric): 1.3.6.1.4.1.11.2.14.11.5.1.99.0.7
Node type: NOTIFICATION-TYPE
Description: This notification signifies that a duplicate IPv4 address has been detected. The DHCP server can detect this condition through the ping-before-offer mechanism. Alternatively, the client may have sent a DHCPDECLINE back to the server; this is assumed to be the result of the client detecting that the address was in use. In either case, the DHCP server marks the IPv4 address as unavailable for leasing to clients. The hpicfDhcpv4ServerNotifyClientOrServerDetected object indicates whether the client or server detected this condition.
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> '' HP-ICF-DHCPV4-SERVER-MIB::hpicfDhcpv4ServerDuplicateAddress snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.11.2.14.11.5.1.99.0.7
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]:55142->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (249959270) 28 days, 22:19:52.70 SNMPv2-MIB::snmpTrapOID.0 = OID: HP-ICF-DHCPV4-SERVER-MIB::hpicfDhcpv4ServerDuplicateAddress
SNMPv3 example:
snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' HP-ICF-DHCPV4-SERVER-MIB::hpicfDhcpv4ServerDuplicateAddress
