hcxPortCellErrRatioThres
Module: COM21-HCXRX-MIB
OID (symbolic): COM21-HCXRX-MIB::hcxPortCellErrRatioThres
OID (numeric): 1.3.6.1.4.1.1141.2.32.1.1.20
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This attribute defines a threshold point at which a hop of the receive channel frequency shall take place. The threshold is defined as the percentage of FEC/HEC errored cells to good cells. The RX card shall calculate this percentage over a one second period, and the threshold must be crossed for the period defined by the hcxPortRatioThresPeriod attribute before a trap is generated. In addition the cells received within one second must be greater than that defined by hcxPortMinErrRatioCells. A value of 0 disables the threshold. Default is 10. If this RX port is connected to an RPM then this threshold is not valid.
What is hcxPortCellErrRatioThres?
This read-write INTEGER (0..100) sets the percentage of FEC/HEC-errored cells to good cells that, once exceeded over a one-second sampling window, triggers a frequency hop, per the description. It works alongside the corrected-FEC threshold but targets uncorrectable/HEC errors specifically, giving the admin a distinct lever for hard failures versus recoverable ones. For example, an admin sets hcxPortCellErrRatioThres tighter than the corrected-FEC threshold so the port reacts faster to unrecoverable cell loss than to merely corrected errors.
