mefSoamAvailabilityChangeAlarm
Module: MEF-SOAM-PM-MIB
OID (symbolic): MEF-SOAM-PM-MIB::mefSoamAvailabilityChangeAlarm
OID (numeric): 1.3.6.1.4.1.15007.1.3.0.1
Node type: NOTIFICATION-TYPE
Description: An mefSoamAvailabilityChangeAlarm notification is sent when the state of mefSoamLmMeasuredStatsAvailForwardStatus or mefSoamLmMeasuredStatsAvailBackwardStatus changes.
The management entity that receives the notification can identify the system from the network source address of the notification, and can identify the PM session reporting the change by the indices in the OID mefSoamLmMeasuredStatsAvailForwardLastTransitionTime, including dot1agCfmMdIndex, dot1agCfmMaIndex, dot1agCfmMepIdentifier, and mefSoamLmCfgIndex.
An agent is not to generate more than one mefSoamAvailabilityChangeAlarm 'notification-event' in a given time interval per PM session as specified by the mefSoamPmNotificationCfgAlarmInterval. A 'notification-event' is the transmission of a single notification to a list of notification destinations.
If additional availability state changes occur within the mefSoamPmNotificationCfgAlarmInterval period, then notification generation for these changes are suppressed by the agent until the current alarm interval expires. At the end of an alarm interval period, one notification-event is generated if any availability state changes occurred since the start of the alarm interval period. In such a case, another alarm interval period is started right away.
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> '' MEF-SOAM-PM-MIB::mefSoamAvailabilityChangeAlarm snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.15007.1.3.0.1
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:
