ArubaOS-Switch Tunneled-node MTU

Hi Airheads,


I'm trying to use Tunneled-node on a Aruba 3810M creating a tunnel back to an 7010 controller. I was able to get that working after i found out you required 6.5 or higher on the controller!! Anyhow, it is working now, however I've found requiring 1584 MTU on the path of the tunnel quite restricting, is there anyway to lower the MTU in the tunnel how the APs do so it is not required to increase the MTU through the network??

1584 MTU is a requirement as far as I can see. I would imagine it's purpose it to ensure that Ethernet packets encapsulated in the tunnel do not get fragmented.
