SNMP Trap: Network Status ------------------------- A trap is generated when a network failures occur. Identification * The originating IP / hostname is used to identify the system generating the traps * The NMS is responsible for associating traps with each managed system, along with clearing of alarms and escalation to the relevant system operator * The trap OID is generic for various SNMP events monitored by the system * The SNMP system name is included as part of the variable binding to assist identification: :: .iso.org.dod.internet.mgmt.mib-2.system.sysName.0 = standalone Trap OID .iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotifications.mteTriggerFired Variable Bindings - Network failures * .iso.org.dod.internet.mgmt.mib-2.system.sysUpTime.0 = 2 minutes (12065) * snmpTrapOID = mteTriggerFired * .iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotificationObjects.mteHotTrigger.0 = 'ERROR: Network Failures' * .iso.org.dod.internet.mgmt.mib-2.dismanEventMIB.dismanEventMIBNotificationPrefix. dismanEventMIBNotificationObjects.mteHotValue.0 = 1 * .iso.org.dod.internet.mgmt.mib-2.system.sysName.0 = standalone Severity: + Critical: ERROR: Network Failures * Info: INFO: Network failures resolved Example: Critical ................. :: Mar 22 14:07:58 robot-sl snmptrapd[1214]: 2019-03-22 14:07:58 [UDP: [192.168.100.3]:18751->[192.168.100.25]:162]: #012iso.3.6.1.2.1.1.3.0 = Timeticks: (1155411) 3:12:34.11 #011iso.3.6.1.6.3.1.1.4.1.0 = OID: iso.3.6.1.2.1.88.2.0.1 #011iso.3.6.1.2.1.88.2.1.1.0 = STRING: "ERROR: Network Failures" #011iso.3.6.1.2.1.88.2.1.3.0 = STRING: "The following network failures occured: netntp: 172.29.1.15" #011iso.3.6.1.2.1.88.2.1.5.0 = INTEGER: 1 #011iso.3.6.1.2.1.1.5.0 = STRING: "VOSS" Example: Info ............. :: Mar 29 13:57:11 robot-sl snmptrapd [1234]: 2019-03-29 13:57:11 [UDP: [192.168.100.3]:32794->[192.168.100.25]:162]: #012iso.3.6.1.2.1.1.3.0 = Timeticks: (165816) 0:27:38.16 #011iso.3.6.1.6.3.1.1.4.1.0 = OID: iso.3.6.1.2.1.88.2.0.1 #011iso.3.6.1.2.1.88.2.1.1.0 = STRING: "INFO: Network failures resolved" #011iso.3.6.1.2.1.88.2.1.3.0 = STRING: "Network failures resolved" #011iso.3.6.1.2.1.88.2.1.5.0 = INTEGER: 0 #011iso.3.6.1.2.1.1.5.0 = STRING: "VOSS"
