<div dir="ltr"><div><div><div>Hi Frank,<br></div>          I agree with you. It seems Brocade doesn't have a similar feature. I think even in Cisco RSU has been recently introduced. However, it is a vital feature for stacks. Perhaps stacks are only intended to offer increased port density not full redundancy.<br>
