Module: DOCS-IF31-MIB
OID (symbolic): DOCS-IF31-MIB::docsIf31CmStatusOfdmaUsT3Exceededs
OID (numeric): 1.3.6.1.4.1.4491.2.1.28.1.12.1.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This attribute denotes the number of times for excessive T3 timeouts. Discontinuities in the value of this counter can occur at re-initialization of the managed system, and at other times as indicated by the value of ifCounterDiscontinuityTime for the associated upstream channel.
What is docsIf31CmStatusOfdmaUsT3Exceededs?
A counter of how many times the modem experienced 'excessive' T3 timeouts (a threshold number of consecutive T3 timeouts) on this upstream OFDMA channel, which per DOCSIS MAC behavior typically forces the modem to attempt ranging on a different channel or re-initialize. This is a stronger escalation signal than the raw T3 timeout counter and worth prioritizing when triaging modems with upstream connectivity problems; the counter can reset on system reinitialization (RFC 2863).
