I'm troubleshooting an issue with a Aruba 3400 Series Mobility Controller and Aruba RAP-3 Remote Access Point.
A user reported random connection drops while connected to the RAP-3. I checked the logs and discovered multiple entries for Tunnel IP change. There was 11 tunnel changes from 8:59am to 16:59, with entry for device reboot.
I found another article on the community board which is almost identical to my experience.

Article is dated from 11/2013. Not sure if a solution was found in the previous posting.
I'm running a two 3400 Series Controller(Active/Standby) with OS 6.4.0.3 with only a combination of 20 RAP-3s and 2 RAP-155 connected.
