Module: DOCS-IF-MIB
OID (symbolic): DOCS-IF-MIB::docsIfCmStatusInvalidMaps

Access: read-only
Description: Number of times the CM received invalid MAP messages. 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 docsIfCmStatusInvalidMaps?
Counts how many invalid upstream bandwidth allocation, MAP, messages the cable modem has received. A high count can indicate upstream noise corrupting MAP messages before the modem can parse them, which in turn disrupts the modem's ability to transmit on schedule.
