some these radios in event of failure contack cisco, create a login then down load files to it, i know this matter of fack i seen it happen, my ap would not join the controler, so i ran ton debug commnads back to back cause a fault cisco servers updated the unit not the controler, in facl ap software newer then controler software, also it added 15 files,
as far i know this only done when a software fault happens now how stop it as only thing u can trace is new account cisco ip address and its happen only few times, i cant say this allways the case, what units it effecks, i do know it happens when one the ports shuts down, or radios turn off do to fault radio reboots, creates two way commactions with cisco downs load software, i do also thinks this happens only throw snmp
why its harder to trace, one thing i would look for event that casue radio reboot , or hole ap to reboot, there your reason how stop this, is hole new ball game now in time if i had 10 to 20 radios i look at i figger it out, as it is i got one, and this odd part software loaded was stand alone software, but do note there still was probem on ap two key files missing running-config startup-config, look for these, throw teck not needed do fack gets its config from controler ap will come on line much faster if the base startup was save to the system ap, it would take less time to join controler,
as most all setting is contain there in , few key things u want look for dhcp server ip address network address gateway address, now running debug commands can set missing config keys, most imported is encription and timeing, timmer given when things to time out also few other timeing settings must be set or ap wont work right debug command should be ran per ap, not controler, as each ap timeing depends on lots factors distace how many aps so one, to note this happen to me 3 days ago i ask for cisco help they denied me odd thing is there very own servers fix the probems but unless they get my logs they cant stop it and i del all the logs , so cisco cant recover information, note if this fix a probem u should have event logs should explane what happen, most likely had do with certifice probem or encription was out sync: this again has to do with timeing on aps, now from what i seen cisco has hidden commands on it , so if u no clue there on system and dont know them u wont find them
