nbsCohpmHistoricMaxOSNR
Module: NBS-COHERENT-MIB
OID (symbolic): NBS-COHERENT-MIB::nbsCohpmHistoricMaxOSNR
OID (numeric): 1.3.6.1.4.1.629.242.23.3.1.66
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Maximum optical signal-to-noise ratio (OSNR) for the historic interval. Unit measurement: 0.1 dB
Not supported value: 0xFFFFFFFF
What is nbsCohpmHistoricMaxOSNR?
nbsCohpmHistoricMaxOSNR is read-only and holds a finalized statistic from a completed past reporting interval for the maximum optical signal-to-noise ratio (OSNR) on this coherent optical interface, i.e. how strong the optical signal is relative to the accumulated noise floor across the fiber path; not-supported is encoded as 0xFFFFFFFF. Unit measurement: 0.1 dB. 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.
