nbsCohpmThresholdsMaxCD
Module: NBS-COHERENT-MIB
OID (symbolic): NBS-COHERENT-MIB::nbsCohpmThresholdsMaxCD
OID (numeric): 1.3.6.1.4.1.629.242.21.1.1.26
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: Persistent. The maximum chromatic dispersion (CD) threshold. Unit measurement: 1 ps/nm
The first time nbsCohpmCurrentMaxCD meets/exceeds this threshold during a given current interval triggers nbsCohpmTrapsMaxCD.
Not supported value: 0x80000000
What is nbsCohpmThresholdsMaxCD?
nbsCohpmThresholdsMaxCD is read-write and holds a persistent, administrator-set alarm threshold for the maximum chromatic dispersion (CD) on this coherent optical interface, i.e. how much the fiber link has spread out the optical signal in time due to wavelength-dependent propagation delay; not-supported is encoded as 0x80000000. Unit measurement: 1 ps/nm. The first time nbsCohpmCurrentMaxCD meets/exceeds this threshold (or, for a Min object, drops below it) during a reporting interval, the device raises the nbsCohpmTrapsMaxCD notification, so a sysadmin sets this value to the maximum chromatic dispersion level they consider unsafe for this specific link's optics and fiber path.
