cOpticalParamLowAlarmThresh
Module: CERENT-OPTICAL-MONITOR-MIB
OID (symbolic): CERENT-OPTICAL-MONITOR-MIB::cOpticalParamLowAlarmThresh
OID (numeric): 1.3.6.1.4.1.3607.2.30.1.1.1.7
Node type: OBJECT-TYPE
Type: OpticalParameterValue
Access: read-write
Description: This object is used to set a low alarm threshold on the optical parameter being monitored.
If the measured value of the parameter,goes lower than the value configured in this object, an alarm will be raised.
When the cOpticalMonParameterType object is set to 'power' for the receive direction and when the interface supports alarms based on loss of light, this object specifies the optical power threshold for declaring loss of light. Also, when optical amplifiers are present in the network, in the receive direction, this value may need to be configured, since the noise floor may be higher than the minimum sensitivity of the receiver.
What is cOpticalParamLowAlarmThresh?
A configurable low alarm threshold for the monitored optical parameter; an alarm is raised when the measured value drops below this configured level.
