NMS can only set this object to monitor(2). In
the monitor(2) state, this local radio will monitor
the remote radio specified in the
cd11IfRemoteRadioMacAddr.
When the remote radio fails or goes down, this local
radio will takeover the functions and became active.
The agent will set the instance of
cd11IfLocalRadioMonitorStatus indexed by the
failed radio cd11IfRemoteRadioMacAddr to 'active'.
This local radio will not monitor any other radios
when it is active, therefore, all other instances of
cd11IfLocalRadioMonitorStatus indexed by the same
ifIndex but different cd11IfRemoteRadioMacAddr
will be set to 'inactive'.
