Thanks, man. It was difficult to tell what that command did from the command reference. It simply says that it sets the bandwidth used to transmit packets. That sounds like more than just a statistical command, but I think you're correct.
The endpoints are 7600s with Sup 720. The MTU in the path is over 9000 and the tunnel MTU is lower than that, but I think we should try lowering the tunnel MTU a bit and possibly use tcp mss adjust. I don't know that it's necessary, though. I believe the end devices themselves have an MTU of 1500, so we should have plenty of room in the tunnel for those packets. I'll dig a little deeper into it.
