authenticationFailure
Module: SNMPv2-MIB
OID (symbolic): SNMPv2-MIB::authenticationFailure
OID (numeric): 1.3.6.1.6.3.1.1.5.5
Node type: NOTIFICATION-TYPE
Description: An authenticationFailure trap signifies that the SNMP entity has received a protocol message that is not properly authenticated. While all implementations of SNMP entities MAY be capable of generating this trap, the snmpEnableAuthenTraps object indicates whether this trap will be generated.
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> '' SNMPv2-MIB::authenticationFailure snmptrap -v2c -c public <manager> '' 1.3.6.1.6.3.1.1.5.5
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]:57554->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (425899730) 49 days, 7:03:17.30 SNMPv2-MIB::snmpTrapOID.0 = OID: SNMPv2-MIB::authenticationFailure
SNMPv3 example:
snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' SNMPv2-MIB::authenticationFailure
