RE: [WIRELESS-LAN] Wireless controllers and Spanning Tree
Here at Emory University, all of our controllers reside at our core router locations and connect using port channel (link aggregation) to the core routers. We explicitly turn off spanning tree on our controllers as there are no opportunities for bridge loops in our architecture. >>-> Stan Brooks - CWNA/CWSP Emory University University Technology Services 404.727.0226 AIM/Y!/Twitter: WLANstan MSN: wlans...@hotmail.com GoogleTalk: wlans...@gmail.com -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:wireless-...@listserv.educause.edu] On Behalf Of Brian J David Sent: Monday, December 15, 2008 1:36 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] Wireless controllers and Spanning Tree I was wondering what other Aruba schools are doing for spanning tree? Do you use it or not? Aruba uses Mono spanning tree so how does it play in your network environment if you are. If you are a Cisco shop same as above for you?

Re: [WIRELESS-LAN] Wireless controllers and Spanning Tree
We connect our controllers with port-channels, which at least provides some redundancy in case of an interface or gbic failure. -- Don Wright Brown University P Please don't print this e-mail or any other electronic documents unless you really need to.

Re: [WIRELESS-LAN] Wireless controllers and Spanning Tree
Each of our controllers are connected with a single link at this point in time. We have not seen a need to dual path these as of yet.

RE: [WIRELESS-LAN] Wireless controllers and Spanning Tree
Our Aruba controllers connect to our other network infrastructure over a distance of about 3 feet, all within our physical datacenter environment. To date, we haven't felt a need to provide redundant links for that span; if and when we need to, I think we are more likely to look at aggregation than at spanning-tree as the mechanism of choice.
