No Backup Tunnel

Frank_Richter — Tue, 05 May 2015 23:48:00 GMT

Hi, I have 2 virtual Controller V2110 at Hyper V. They are in availability mode (fast failover). All APs in the same subnet as the physical Interfaces of both controllers are established the primary and backup tunnel. The APs there are not in the same subnet do not establish the backup tunnel. I changed the Tunnel MTU size to 1300 but it doesnt work.

I would suggest collecting the trace log packages on a few of your access points and provide them to GTAC support for review:

How to get those files:

Also get a tech support file from both your controllers:
