rdnIfCmtsUpChCtrReqNoEnergy
Module: RDN-CMTS-MIB
OID (symbolic): RDN-CMTS-MIB::rdnIfCmtsUpChCtrReqNoEnergy
OID (numeric): 1.3.6.1.4.1.4981.2.2.28.1.2
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Current count, from CMTS initialization, of contention request mini-slots subjected to No Energy on this upstream logical channel. This includes all contention mini-slots for IUC1 applicable to bursts that the CMTS detected but found as no energy. Discontinuities in the value of this counter can occur at reinitialization of the managed system, and at other times as indicated by the value of ifCounterDiscontinuityTime for the associated ifIndex.
What is rdnIfCmtsUpChCtrReqNoEnergy?
Read-only Counter32, counted since CMTS initialization, of contention request mini-slots (IUC1 bursts) the CMTS detected but classified as having no energy on this upstream logical channel; discontinuities are flagged via ifCounterDiscontinuityTime. A rising no-energy count can indicate modems failing to transmit contention requests at all, e.g. due to a plant outage or misconfigured transmit power.
