espAuthFailureTrap

Module: IPSEC-SA-MON-MIB

OID (symbolic): IPSEC-SA-MON-MIB::espAuthFailureTrap

OID (numeric): 1.3.6.1.3.98.1.4.0.1

Node type: NOTIFICATION-TYPE

Description: IPsec packets with invalid hashes were found in an inbound ESP SA. The total number of authentication errors accumulated is sent for the specific row of the 'ipsecSaEspInTable' table for the SA; this provides the identity of the SA in which the error occurred.

Implementations SHOULD send one trap per SA (within a reasonable time period), rather than sending one trap per packet.

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> '' IPSEC-SA-MON-MIB::espAuthFailureTrap
snmptrap -v2c -c public <manager> '' 1.3.6.1.3.98.1.4.0.1

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]:64318->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (342235966) 39 days, 14:39:19.66
  SNMPv2-MIB::snmpTrapOID.0 = OID: IPSEC-SA-MON-MIB::espAuthFailureTrap
