authFailure

Module: VPN-MIB

OID (symbolic): VPN-MIB::authFailure

OID (numeric): 1.3.6.1.4.1.1866.0.4

Node type: NOTIFICATION-TYPE

Description: SKIP Authentication error. The authentication key in the offending packet was not correct. This trap shows up on the VPNmanager as Invalid Authentication Signature.

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> '' VPN-MIB::authFailure
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.1866.0.4

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]:59635->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (53788403) 6 days, 5:24:44.03
