Hi
I have just had a radio failure on one of our Cisco AIR-AP1231G-E-K9 access points. A reload fixed it but I would like to try and figure out what happened. Can anyone suggest what might be the problem? Here the log contents prior to the reload :-
ap0#sh logging Syslog logging: enabled (0 messages dropped, 3 messages rate-limited, 0 flushes, 0 overruns, xml disabled, filtering disabled) Console logging: level debugging, 1876 messages logged, xml disabled, filtering disabled Monitor logging: level debugging, 0 messages logged, xml disabled, filtering disabled Buffer logging: level debugging, 1878 messages logged, xml disabled, filtering disabled Logging Exception size (4096 bytes) Count and timestamp logging messages: disabled Trap logging: level informational, 981 message lines logged
