nbsCohpmThresholdsMaxPDL
Module: NBS-COHERENT-MIB
OID (symbolic): NBS-COHERENT-MIB::nbsCohpmThresholdsMaxPDL
OID (numeric): 1.3.6.1.4.1.629.242.21.1.1.96
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: Persistent. The maximum polarization dependent loss (PDL) threshold. Unit measurement: 0.1 dB
The first time nbsCohpmCurrentMaxPDL meets/exceeds this threshold during a given current interval triggers nbsCohpmTrapsMaxPDL.
The reserved value 0xFFFFFFFF disables notifications for this event.
What is nbsCohpmThresholdsMaxPDL?
nbsCohpmThresholdsMaxPDL is read-write and holds a persistent, administrator-set alarm threshold for the maximum polarization dependent loss (PDL) on this coherent optical interface, i.e. how much the fiber path's attenuation varies depending on the signal's polarization state; not-supported is encoded as 0xFFFFFFFF. Unit measurement: 0.1 dB. The first time nbsCohpmCurrentMaxPDL meets/exceeds this threshold (or, for a Min object, drops below it) during a reporting interval, the device raises the nbsCohpmTrapsMaxPDL notification, so a sysadmin sets this value to the maximum polarization dependent loss level they consider unsafe for this specific link's optics and fiber path.
