snmpTlstmServerCertificateUnknown

Module: SNMP-TLS-TM-MIB

OID (symbolic): SNMP-TLS-TM-MIB::snmpTlstmServerCertificateUnknown

OID (numeric): 1.3.6.1.2.1.198.0.1

Node type: NOTIFICATION-TYPE

Description: Notification that the server certificate presented by an SNMP over (D)TLS server was invalid because no configured fingerprint or CA was acceptable to validate it. This may be because there was no entry in the snmpTlstmAddrTable or because no path could be found to known Certification Authority.

To avoid notification loops, this notification MUST NOT be sent to servers that themselves have triggered the notification.

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> '' SNMP-TLS-TM-MIB::snmpTlstmServerCertificateUnknown
snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.198.0.1

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]:60790->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (462388086) 53 days, 12:24:40.86
  SNMPv2-MIB::snmpTrapOID.0 = OID: SNMP-TLS-TM-MIB::snmpTlstmServerCertificateUnknown
