The total time, in seconds, this standby monitoring
radio unit can tolerate the failure of polling
of the active radio unit. After this duration, one
more failure of the polling will trigger this hot
standby monitoring radio to take over and become an
active radio. It will then stop all monitoring
activity and set the instance of
cd11IfLocalRadioMonitorStatus indexed by the
failed radio cd11IfRemoteRadioMacAddr to 'active'.
