It would work most of the time, but when testing we found there are times that we couldn’t get an iPad to find the AppleTV till it was rebooted and we were concerned with distance. IMO it works better for conference rooms and possibly smaller classrooms if you don’t mind it broadcasting. We are still using our Mirror App though.

RE: wireless as network standard?
Our model use to be port per pillow. Now it's, AP per room. We found that the newer models of AP, have wired ports and POE pass-through. It requires two Ethernet runs to take full advantage. Plus you still have to have POE at the switch (IDF) level. However, the cost of running 4 wires compared to 2 This has served us well in older buildings and newer with tons of metal and concrete. The speeds will only get better for AP's. Students use wifi over wired anyway. Having 'wired' ports allows us to provide 1GB for IPTV, gaming consoles (that lack wifi), and VOIP phones.

We thought maybe it was a broadcast/multicast problem, but traffic graphs show that the MC rate is very low overall, and doesn't spike when the issues occur. Even when the issue occurs, it only affects some clients, and the clients it affects can vary from one day to the next. So I'll try disabling v6, but that seems a little too deterministic... ;-) As a side note, we also have an issue with our Aruba controller where it won't pass v6 traffic at all, so I doubt this is the case (as soon as we say ipv6 firewall enable, all v6 traffic gets dropped, even if the ACL is any any any permit).

RE: High Number of Disconnections - Mac 10.5 and up
We also tried..it will go into sleep mode while some tasks are still running, thus disconnects, run the command alone to keep it awake no matter what. See if this helps the disconnect issue you are having. caffeinate -u -t 3600 3600 in the above command is the number of seconds to keep the system awake. What's interesting is that you can effectively set your Mac to shut down at a specific time (that is, the built-in sleep mechanism will start counting when that time runs out). You can also run the command alone to keep your Mac awake until you stop it by pressing Control-C.

RE: gaming consoles
Our goal was to support game consoles, but keep the traffic off of our production WAN. Also, we had a flood of LG070 VOIP phones as well. Here's what we did... 1.)Create a separate WAN for game consoles and VOIP phones (specifically the LG070). 2.)Create a separate SSID (hidden) for this purpose 3.)Gamers must contact us and register their MAC 4.)We enter their MAC as username and password in the internal DB. - for authentication, we zero this out each year so students need to re-register.

RE: Wireless only dorms, advice?
We just finished rolling out wifi to all dorms. Each dorm is uniquely different in terms of age and/or construction materials. I used a variety of tools to determine placement of ap's. However, the first thing I did was place one or two AP's in area's that I thought would be strategic. I used Air Magnet to determine if the heat map would provide adequate coverage. I did a total of 16 dorms like this and ended up adding 12 additional AP's in area's that had little coverage. We installed a total of 424 Ap's and we added 12 more, not bad. That said, I still have a small percentage of users with 'wire only' devices. Not to mention the game consoles that are still wire only. That said, we will be building a new dorm next year. I plan on wifi only but will include wired ports as well. Granted, not the port per pillow we have been use to, but maybe port per room. I haven't made a decision yet. Wireless is still half duplex and the best I can get out of 802.11n is 300mps. So, applications like IPTV, Digital Signage still require a wire. Not to mentioned fire alarms, HVAC. Phones, emergency notification...all things that we need to run a building, still require a wire. I have had as many as 20 clients on one AP, with no issues. However, as more bandwidth intensive apps are available (not to mention the increase in devices), I suspect I will have to limit this. So far, there has not been a need.

Sorry to resurrect an old thread, but there was no clear solution at the time. Since then, I have been working with setting up 802.1X WPA2-Enterprise in our Aruba wireless environment. I believe that I have found a reasonable solution. By default, Aruba enables Opportunistic Key Caching (OKC) that enables a cached pairwise master key (PMK) to be used when roaming to a new AP, enabling faster roaming. In Aruba systems, if opp-key-caching is enabled, validate-pmkid (disabled by default) tells the controller to check the PMK ID sent by the client. The client must send the PMKID to indicate that it supports PKC. Otherwise, a full 802.1X authentication takes place. I was personally seeing similar issues to those discussed in this thread. After I enabled the validate-pmkid setting, the issues vanished. This change should have no impact on clients that properly use OKC. People with other vendor's systems likely have similar configuration options.

RE: WiFi blockers in classrooms
We can push out different SSID's with ACL's that limit what an authenticated user can access. However, our AP heatmap shows leakage from AP's above and below the floors where the classroom are. So, in a nutshell, it wasn't worth it (blocking that is). Especially true once you incorporate emergency notification via 802.11x. I would agree with other colleagues comments, it's an academic/classroom/Professor issue. Northeastern, I believe, did not roll out 802.11x in the classrooms, because the Professors did not want it.

Since the start of the semester we have had issues come up that we have been addressing, but we are now encountering something that we never faced before - it seems more and more that the majority of new issues we are dealing come from Apple laptops and mobile devices. We have heard of some of the larger reported issues about Apple, such as the DHCP issues with the original iPad iOS. We have also done some of our own research on this and see Apple mentioned numerous times in regards to wireless connectivity issues, but we don't know if we are seeing this because this is what we are looking for or if because it is the reality of the situation. An example of this type of issue is that a student applied Apple updates to her computer last Friday and then could not get an IP address afterwards on our wireless network, though she could still use her wireless router at home. Calling Apple about this resulted in them telling us that if the computer can connect in one place but not another that it is our problem and not an issue with the laptop, even though many other Apple computers with the same version of the OS could connect to our network. We continue to troubleshoot and look to see if there is something that is about our wireless network configuration that is causing problems. However, we would like to see if others have experienced similar types of issues on their campuses. Do you see a preponderance of wireless issues over time relating to Apple products? If this has been the case for you, were you successfully able to address issues with Apple? Did you have to go back to your wireless vendor to fix these issues? Does this sound like something unique to our experience here? We look forward to hearing what others have experienced.

RE: Guest Wireless Questions
Gordon College Answers We are in the middle (POC) of using Captive Portal. It's the same idea used in hotels. Credentials will be available via our excellent Support Staff and Aux. Services. In other words, you must come to us if you need to use our guest network. The SSID only allows forward facing traffic and never touches our internal net. We have a CALEA identifier/logger on our NetEQ box.

RE: [WIRELESS-LAN] 'Clustering' and 'failover' in the context of Aruba
Hi John, We just went through the same scenario. We now have an Aruba/Alcatel 6000 with dual controllers...200 AP's as well. I concluded the following. 1.) Two controllers (same box) side A B, A-side is active, B-side is redundant. A-side fails, B-side takes over 2.) Major/minor upgrade - Upgrade B-side, swap, everything looks good, do a copy/synch to the A-Side 3.) Major/minor upgrade - Upgrade B-side, swap, upgrade fails, revert back to A-side 4.) Minor hardware failure - 1 controller fails, still operational 5.) Major hardware failure - backplane failure = tons of phone calls Item #5 is my weakest link. However, because the 6000 has dual-everything (except the chassis), I felt my exposure was minimal. I could not justify the cost of an additional 6000 for 100% redundancy. I looked at the smaller boxes with decentralized distribution...but the smaller boxes couldn't handle all 200 AP's simultaneouslyPlus it just adds complexity to our already overworked staff (troubleshooting would be more complicated). I hope this is helpful. Russ -Original Message- From: John Rodkey [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 22, 2007 7:24 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] 'Clustering' and 'failover' in the context of Aruba We are currently considering expanding our existing wireless environment to cover additional dorms. By doing so, we will exceed the capacity of our current controller, and can either add an additional controller card or for a slight incremental cost, add another controller. We planned to add the additional controller, with the idea that the controller would allow redundancy/failover/clustering to happen, so that if one controller were to go down, for instance, the other would take over. We were subsequently told that this was a faulty understanding of the failover function. So we thought we might be able to try another approach: every other WAP would be controlled by alternating controllers. That way, if controller A, with waps 1,3,5,7,9... on it were to go down, the coverage in any given building would be halved, because controller B, with waps 2,4,6,8 ... would continue to run. Nope, that is a bad idea, says the contact: each controller will maintain its own heat map and routing info, etc. and as a result, there would be nowhere to look for a unified picture of the wireless network. So I'm confused: what is the exact nature of controller clustering or failover under Aruba? Given somewhere in the neighborhood of 200 APs, how should one configure the controllers John ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
Re : microcell vs virtual cell
Hi Everyone, Just wanted to weigh in on this conversation. We went through this same process at Gordon College about 4 years ago. We looked at Meru, Trapeze, AirSpace and Aruba. During this process, there were no independent studies or analysis of anyone's product. Gordon College pilot's any new technology. Our pilots run between 30-60 days. We also rely on analysis by Network Computing, Gartner and Tolly. Typically, they do a very good, non-bias, review of products and technology. Next we look at the company and the amount of $$ they spend on RD, patent ownership and whether or not them have engineers or a presence on standards committee's. It's the standards that really catch my eye. Hopefully, if they conform, than I have positioned myself and the institution for the future. If not, then the trouble begins. Needless to say, we chose Alcatel/Aruba. They conform to standards. So far, we have rolled out WifiVOIP, Multicast (video/audio), wifi VPN, seamless roaming. It all works. I read the article regarding Network Computing analysis of CISCO vs. Meru. Honestly, they did a very thorough job. What I got out of the article was that indeed Meru was/is tweaking the 802.11 duration value. To me, this is a red flag. This means they are not conforming to standards. Has Meru responded to Network World or their customers? Seems to me if this wasn't true, there would be lawsuits or at least a rebuttal. Here's one of the engineers e-mail address, [EMAIL PROTECTED] I would contact him and ask the question. Anyway, let's get back to testing or piloting technology. By virtual cell vs traditional micro-cell WiFi I assume you are talking about having multiple access points advertise the same BSSID on the same channel. Virtual cell appears to clients as a single access point. In this definition virtual cell would result in more clients contending for the given channel within a larger coverage area. Contention in WiFi is generally managed by CSMA/CA (collision avoidance). CA is used instead of CD (collision detection) because clients are sometimes not within range of other clients. You can create virtual-contention to go with the virtual-cells by tweaking access point timers to be shorter than client timers, but the single channel or access point bandwidth is fixed. You raise a very good question about the data/analysis since the number of vendors promoting such concepts is very limited. Place 3 micro-cell access points on 3 different channels in a coverage area. Associate 3 clients 1 per access point. Measure. Place 3 virtual-cell access points on same channel in same coverage area. Associate 3 clients. Measure. Be sure to take bi-directional measurements with simultaneous TX/RX to experience the half-duplex nature of WiFi radio. I am confident you will push more packets over 3 channels than 1. Be sure to power-off the system you are not testing. Shorting timers or counters by one system can adversely impact other client and access point devices even with only background traffic. There is 3rd party vendor/bake-off documenting the results but you have indicated that you do not consider it.
