nbsCohpmThresholdsMinDGD
Module: NBS-COHERENT-MIB
OID (symbolic): NBS-COHERENT-MIB::nbsCohpmThresholdsMinDGD
OID (numeric): 1.3.6.1.4.1.629.242.21.1.1.33
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: Persistent. The minimum differential group delay (DGD) threshold. Unit measurement: 1 ps
The first time nbsCohpmCurrentMinDGD meets/is below this threshold during a given current interval triggers nbsCohpmTrapsMinDGD.
The reserved value 0xFFFFFFFF disables notifications for this event.
What is nbsCohpmThresholdsMinDGD?
nbsCohpmThresholdsMinDGD is read-write and holds a persistent, administrator-set alarm threshold for the minimum differential group delay (DGD) on this coherent optical interface, i.e. how much delay skew polarization-mode dispersion has introduced between the two polarization axes of the signal; not-supported is encoded as 0xFFFFFFFF. Unit measurement: 1 ps. The first time nbsCohpmCurrentMinDGD meets/exceeds this threshold (or, for a Min object, drops below it) during a reporting interval, the device raises the nbsCohpmTrapsMinDGD notification, so a sysadmin sets this value to the minimum differential group delay level they consider unsafe for this specific link's optics and fiber path.
