Attached is a high-level diagram of the site's LAN and WAN connection back to its primary data center. I have an Aruba 200 controller as the site local controller and five APs...three 65s and two 70s. Controller is running AOS 220.127.116.11. The site only has two cisco 2950 switches and a single VLAN. The 2950s are connected to each other via their gigE ports in an L2 etherchannel. Three APs are on one switch along with the controller, and the other two are on the second switch.
Randomly, one or maybe two of the APs will lose their connection to the local controller and fail back to the master, where it runs happily until LMS preemption kicks in and it goes back to the local. The only logs I really see in the local controller are below:

AP04/05 are the 70s, AP01/02/03 are the 65s. AP03 seems to be the biggest offender. Everything I check on the LAN is spotless. No switchport errors, no utilization issues, nothing. There are no reported general LAN issues reported at the site either. The 2950s are at the latest code as well. What else from an Aruba perspective can I even look at to figure out what may be the issue with the broken connections?

Try the below steps
1. Run ap tech-support and look for rebootstrapping reason. command "show ap tech-support
2. Is AP03 connected to the same switch where the controller is connected.
3. Are you sure if AP failover to master you don't see this the same problem?
4. reprovision AP03 to master and see if you hit the problem.
5. when did you upgrade the controller? did you see the same problem in the previous code also?
6. have some on at the site to swap the AP's and see if it fixes ( to isolate the hardware problem)
7. try to disable L2 ethch and see.
8. if above steps didnt help enable ap debug get the logs.tar with tech-support & ap tech-support contact Aruba support.

asap_gre_err: Received ICMP (DEST_UNREACH, PROT_UNREACH) from
Kind of shows me that there's something up with the controller. I'm going to open up a TAC case at this point.
