hcxPortRealTimeMinNoise
Module: COM21-HCXRX-MIB
OID (symbolic): COM21-HCXRX-MIB::hcxPortRealTimeMinNoise
OID (numeric): 1.3.6.1.4.1.1141.2.32.1.1.29
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: ::= { com21HcxUpstrmStatsEntry 29 } This attribute provides a realtime min noise level in dBmv. The attribute is updated every approx 5 seconds and provides the minimum noise level during that period.
What is hcxPortRealTimeMinNoise?
This read-only Integer32 reports a near-real-time minimum noise reading in dBmV for this receiver port, sampled at roughly the same 5-second cadence described for the corresponding mean and max real-time noise attributes on this port, even though its own description text is empty. It gives an admin the quietest recent sample for live troubleshooting alongside the real-time mean and max values. For example, during a live test, an admin watches hcxPortRealTimeMinNoise stay flat while hcxPortRealTimeMaxNoise spikes, indicating an intermittent rather than constant noise source.
