hcxPortCurrMinRxNullCells
Module: COM21-HCXRX-MIB
OID (symbolic): COM21-HCXRX-MIB::hcxPortCurrMinRxNullCells
OID (numeric): 1.3.6.1.4.1.1141.2.32.1.1.5
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: Represents the number of null cells received in the current 15 minute period.
What is hcxPortCurrMinRxNullCells?
This read-only Gauge32 counts null (idle/filler) cells received on the RX port during the current 15-minute interval, per the description. A high proportion of null cells relative to real cells tells an admin the upstream channel has spare capacity that is not being used for actual traffic right now. For example, an admin compares hcxPortCurrMinRxNullCells against hcxPortCurrMinRxCells to estimate current upstream channel utilization before the official utilization gauge updates.
