nbsCohpmCurrentAveDGD
Module: NBS-COHERENT-MIB
OID (symbolic): NBS-COHERENT-MIB::nbsCohpmCurrentAveDGD
OID (numeric): 1.3.6.1.4.1.629.242.22.3.1.30
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Average differential group delay (DGD) seen in the current interval. Unit measurement: 1 ps
Not supported value: 0xFFFFFFFF
What is nbsCohpmCurrentAveDGD?
nbsCohpmCurrentAveDGD is read-only and holds a live statistic for the reporting interval now in progress for the average 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. A sysadmin polls it to watch this metric evolve in real time during the interval still underway, and compares it against the matching nbsCohpmThresholdsAveDGD alarm setting to see how close the link is running to its configured limit.
