This was not work as expected, in my IAP Cluster, when client roams from AP1> AP2, the aruba IAP sends a Stop Session accounting from AP1 and an Start Session Accounting from AP2, this is a problema because i use Sophos Radius SSO, then when the client is loged out from Firewall, his active connections is closed.
Apps that use google cloud messaging stop working for few minutes when the device roams.
Its possible to config Aruba IAP Cluste to do not send accountig stop when client roams?
