Command Usage
• A fault alarm can generate an SNMP notification. It is issued when the MEP fault notification
generator state machine detects that a configured time period (see the mep fault-notify
alarm-time command) has passed with one or more defects indicated, and fault alarms are
enabled at or above the priority level set by this command. The state machine transmits no
further fault alarms until it is reset by the passage of a configured time period (see the mep
fault-notify reset-time command) without a defect indication. The normal procedure upon
receiving a fault alarm is to inspect the reporting MEP’s managed objects using an appropriate
SNMP software tool, diagnose the fault, correct it, re-examine the MEP’s managed objects to
see whether the MEP fault notification generator state machine has been reset, and repeat
those steps until the fault is resolved.
• Only the highest priority defect currently detected is reported in the fault alarm.
• Priority defects include the following items:
