OID (numeric): 1.3.6.1.4.1.1166.1.100.0.100

Description: This trap is issued to indicate that the SDM detected a change to the state of an active alarm for a managed object. In other words, an active alarm was cleared or the perceived severity of the alarm changed. The sdmProbableCause and sdmProbableCauseText varbinds identify the alarm while the sdmObjectIPaddress and sdmObjectName varbinds identify the managed object. The trapPerceivedSeverity varbind identifies the current severity.

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> '' SDM-MIB::trapAlarmTransition
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.1166.1.100.0.100

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:
