Description: This attribute specifies the percentile (such as 2nd percentile or 5th percentile) of all active subcarriers in an OFDM channel at which the ThresholdRxMerValue occurs. That is, (Percentile) % of the subcarriers have RxMER <= ThresholdRxMerValue.
What is docsIf31CmtsCmUsOfdmaChannelRxMerThreshold?
A configurable percentile value (default 2, meaning the 2nd percentile) that tells the CMTS which point in the sorted RxMER distribution of subcarriers to report as the 'threshold' value: X% of subcarriers have RxMER at or below the corresponding ThresholdRxMerValue. Admins can adjust this to focus monitoring on the worst-performing subcarriers, e.g. raising it to look at the bottom 5% instead of the bottom 2% when chasing a marginal channel.
Examples
Walk all instances (SNMPv2c):
