nbsCohpmHistoricMaxDGD
Module: NBS-COHERENT-MIB
OID (symbolic): NBS-COHERENT-MIB::nbsCohpmHistoricMaxDGD
OID (numeric): 1.3.6.1.4.1.629.242.23.3.1.36
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Maximum differential group delay (DGD) for the historic interval. Unit measurement: 1 ps
Not supported value: 0xFFFFFFFF
What is nbsCohpmHistoricMaxDGD?
nbsCohpmHistoricMaxDGD is read-only and holds a finalized statistic from a completed past reporting interval for the maximum 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. Because it belongs to a completed interval selected by nbsCohpmHistoricSample (1 = most recent), a sysadmin pulls a run of these to build a trend of this port's optical health over recent 15-minute or 24-hour periods rather than relying on a single live reading.
