ETH_CFM

dot1agCfmFaultAlarm

Table 1. dot1agCfmFaultAlarm properties
Property name	Value
Application name	ETH_CFM
Event ID	2001
Event name	dot1agCfmFaultAlarm
SNMP notification prefix and OID	IEEE8021-CFM-MIB.dot1agNotifications.1
Default severity	minor
Source stream	main
Message format string	MEP $dot1agCfmMdIndex$/$dot1agCfmMaIndex$/$dot1agCfmMepIdentifier$ highest defect is now $dot1agCfmMepHighestPrDefect$
Cause	A MEP has a persistent defect condition. A notification (fault alarm) is sent to the management entity with the OID of the MEP that has detected the fault. Whenever a MEP has a persistent defect, it may or may not generate a Fault Alarm to warn the system administrator of the problem, as controlled by the MEP Fault Notification Generator State Machine and associated Managed Objects. Only the highest-priority defect, as shown in Table 20-1, is reported in the Fault Alarm. If a defect with a higher priority is raised after a Fault Alarm has been issued, another Fault Alarm is issued. The management entity receiving the notification can identify the system from the network source address of the notification, and can identify the MEP reporting the defect by the indices in the OID of the dot1agCfmMepHighestPrDefect variable in the notification: dot1agCfmMdIndex - Also the index of the MEP's Maintenance Domain table entry (dot1agCfmMdTable). dot1agCfmMaIndex - Also an index (with the MD table index) of the MEP's Maintenance Association network table entry (dot1agCfmMaNetTable), and (with the MD table index and component ID) of the MEP's MA component table entry (dot1agCfmMaCompTable). dot1agCfmMepIdentifier - MEP Identifier and final index into the MEP table (dot1agCfmMepTable). Reference: 802.1ag clause 12.14.7.7
Effect	N/A
Recovery	Investigation is required to determine the cause of the MEP alarm.
