cd11IfLocalRadioMonitorStatus
Cisco DOT11 Interfaces Local Radio Monitor Status
1.3.6.1.4.1.9.9.272.1.1.1.11.1.4
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'.
