nbsCohpmThresholdsMaxCFO
Module: NBS-COHERENT-MIB
OID (symbolic): NBS-COHERENT-MIB::nbsCohpmThresholdsMaxCFO
OID (numeric): 1.3.6.1.4.1.629.242.21.1.1.56
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: Persistent. The maximum carrier frequency offset (CFO) threshold. Unit measurement: 1 MHz
The first time nbsCohpmCurrentMaxCFO meets/exceeds this threshold during a given current interval triggers nbsCohpmTrapsMaxCFO.
Not supported value: 0x80000000
What is nbsCohpmThresholdsMaxCFO?
nbsCohpmThresholdsMaxCFO is read-write and holds a persistent, administrator-set alarm threshold for the maximum carrier frequency offset (CFO) on this coherent optical interface, i.e. how far the received optical carrier's frequency has drifted from the local oscillator's expected frequency; not-supported is encoded as 0x80000000. Unit measurement: 1 MHz. The first time nbsCohpmCurrentMaxCFO meets/exceeds this threshold (or, for a Min object, drops below it) during a reporting interval, the device raises the nbsCohpmTrapsMaxCFO notification, so a sysadmin sets this value to the maximum carrier frequency offset level they consider unsafe for this specific link's optics and fiber path.
