cmEthernetAccPortThresholdVarOprVariance
Module: CM-PERFORMANCE-MIB
OID (symbolic): CM-PERFORMANCE-MIB::cmEthernetAccPortThresholdVarOprVariance
OID (numeric): 1.3.6.1.4.1.2544.1.12.5.1.4.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: Variance in the Optical Power Received (in dbM), beyond which threshold crossing alert will be generated.
What is cmEthernetAccPortThresholdVarOprVariance?
This read-write Integer32 sets the allowed variance in Optical Power Received (in dBm) beyond which a threshold-crossing alert is generated, exactly as the MIB describes. An admin uses it to catch a fiber transceiver drifting away from its own baseline before the link fails outright, rather than only alarming on an absolute floor. Setting cmEthernetAccPortThresholdVarOprVariance to 4 dB on access port 23 means that transceiver's optical power has to wander that far from its established baseline before the operator gets paged.
