Actually, this is not entirely true. If multiple vnics are created on top of dlmp then they will be spread across the underlying interfaces. This will give you both in and out load spread in total, although each vnic will be constrained by a single underlying interface. Also, with some switches one can do aggregation across switches as well. -- Robert Milkowski http://milek.blogspot.com ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
