I have lots of SW 3850 which failed on inventory collection with an error:
" Collection Status
Collection Other error: Wireless Controller inventory collection failed.
Status : Failure to collect feature DCAConfig"
Half of the devices (50 upon 100) have this error.
Allthoug Prime can archive the configuration of all switches..
When I tried to Re-sync the faulty devices , a few goes OK: ( i.e. inventory completed)
I tried to increase the timer ( snmp from 6 sec to 18 sec, and SSH from 60 to 180 sec) without success.
All the SW 3850 have the same snmp and tacacs config..
They are not configured as wireless controller.
Could someone help me ?
