Hi [NAME]-gmail.com,   This is the user guide for OS version 10.5.0: [URL]   The switch contains load balancing command, but I am unsure if it is related to Aruba's functionality. I would recommend to contact product sales to check with their sales engineer for specific product model. 
ARUBA[URL] wanna ask1. what is similar function of it in Force102. if Aruba side is L4 and Force10 side is L3 trunkwill L4 talk to L33. which switch model and os version support that tq
L4 Trunk Load Balance
