What is docsIf3CmStatusInvalidMaps?
This counter records how many times a cable modem received invalid MAP (Media Access Plan) messages from the cable access network. MAP messages tell the modem when it can transmit, so invalid messages disrupt communication. An operator checks this counter when a modem has poor connectivity or cannot access the network properly.
