This read-only flag reports whether the COM21 NMAPS polling daemon is required to poll (required) or may skip polling (optional) for the associated device. It tells an administrator whether the current alert-logging cycle depends on active SNMP polling of that element or whether the daemon is free to defer it, which matters when tuning polling load on a large cable network. For instance, if a device already reported its status via a trap, nmapsDaemonForcePoll might read optional(0) so the daemon does not waste a poll cycle re-checking it immediately.
