Re: [WIRELESS-LAN] Deployment of AirFiber bridges
I’ve got three pairs running and will be adding another couple in the coming months. Current distances are 300m (-43 dBm), 450m (–46 dBm), and 850m (–53 dBm) all on 6’ non-penetrating masts on school roofs. Two of the sets have been up since early last Summer. All are getting around 775 megabit full duplex and I haven’t had any connectivity drops due to rain, snow, or ice. For the price you can’t beat them, just make sure you ground them well as they’re really sensitive to it.

Re: [WIRELESS-LAN] Reasons for NOT upgrading to iOS 7?
I second Julian's opinion about speed on older devices as I too got stuck with a terribly slow iPhone 3G after the iOS 4 upgrade.

Re: [WIRELESS-LAN] [Off-Topic] Computer Labs
At Old Dominion University (my previous employer) we went to a combination of a few central labs, a virtual computer lab, and a learning commons area. The students really embraced the learning commons which included configurable furniture with power outlets, group meeting rooms with TVs/projectors, printers that were accessible wirelessly, as well as some computer stations. Most students opted to just bring their own laptops or tablets and then used our power, wi-fi, printers, and tvs/monitors and were very happy with the setup. In most of the new academic buildings going up rather than providing dedicated labs the decision was made to offer more learning commons spaces. I really see this as the future of the university computer lab -- offering an comfortable area for students to work on their own laptops/tablets while being able to utilize university resources and meeting spaces. http://www.odu.edu/learningcommons/ Josh Robertson Sr. Wireless Engineer / InfoSecurity Admin Denver Public Schools Department of Technology Services (720)423-3675 To open a new support call, please call the DoTS Hotline at 720-423-3888 On 8/21/13 2:56 PM, Eric T.

RE: [WIRELESS-LAN] students per AP in residence halls
Mike, With the WiSM2 on 7.2 you can use RF Profiles to manage your thresholds. The option is under Wireless-RF Profiles and then you can assign it to APs under the AP Groups (WLANs-Advanced-AP Groups). This way you can tweak the settings at whatever scale you want.

We didn't like the idea of micromanaging power levels or the huge cost increase and security concerns of placing WAPs in the rooms. In Cisco land, a workaround for now, was increasing the power threshold from the default -70 to -50 whenever there are three or more neighbors. I've only seen the way to do this globally per each controller, and changes are only invoked by the Power Assignment Leader. I was hoping to be able to create groups and manage RRM per building but I'm either overlooking that feature or imagined it. We're using wism2's on 7.2 code. So for now this is a campus-wide adjustment. Given the majority of our coverage model is corridor based in academic and res hall buildings, it appears to be a benefit in most locations. We have fairly good overlap so it is rare that any given WAP is at full power, even with the increased threshold. If we end up with too much channel noise we might reduce the threshold a bit.

The issue we've had is not one of density but one of coverage; in some site surveys we'e conducted recently in our residential spaces, we are finding that one AP might cover only a small amount of students, say, 6-12 reliably. The challenges have been that our residential halls are old, double-brick with all sorts of reinforcement. We are site surveying for 2.4GHz - we can't justify the cost of a high density deployment to support 5GHz everywhere. I have also noticed that HP produce a small active wall-outlet switch+AP which is PoE powered. It is b/g/n 2.4GHz-only (sigh) and is aimed at the hospitality industry. Where are people placing their APs? We currently place them in the corridor, however our challenge has been that the APs see each other and RRM wants to drop the power levels. We also run into issues if we have more than three APs in direct line of sight. I'm curious - how do hotels deal with this problem? They have similar construction and requirements.

RE: [WIRELESS-LAN] Client location / tracking...
I got a Fluke AirCheck this summer and have found its locate feature to work quite well with the (optional) directional antenna.

RE: [WIRELESS-LAN] Cisco Bonjour gateway webinar- anyone attend?
I asked many of the same questions as Anders without a reply so I'm also wondering if they just weren't prepared/hadn't thought of the problems associated with having the devices on wired, if having vlans across a L3 boundary will require a controller there to terminate them, and if/how roaming works with it. Hopefully when they get to beta testing these issues will be handled and information provided.

I listened to it. It basically sounds like they're running an avahi process on the controller and caching any service advertisements on any VLANs (including wired VLANs) trunked to the controllers. Of course you need to have your controllers in a convenient location to get all of necessary the VLANs to them. When a client makes a service discovery request, the controller serves up the information from its cache. They are planning some level of filtering to restrict which clients can see which services (Apple TV's, etc). But, it wasn't yet clear what could be used for filtering (cilent MAC, username, radius attribute, etc). Per-SSID filtering was shown in the demo, but when I asked the moderators, they said they were considering all of the above filtering options. So, this solution does help solve the cross-subnet boujour service discovery problems in our environment, but we'll still face authorization issues. We can't simply create a 'student' and 'faculty' SSID and only allow the faculty to see Apple TV's. There are times when a student should be allowed to display their iDevice's screen on the classroom's AppleTV. Ideally that should be a privilege granted by the faculty member to a specific student as needed for a given class session. This really isn't something the network can 'bandaid'. It really needs to be a feature of the Apple products. The basic password security of Apple TV's simply isn't sufficient. Unfortunately the webcast didn't address any possibility of location-aware service discovery to limit the number of Apple TV's that might show up on an iDevice. On a side note, the Cisco webcast did cover their addition of NBAR support to the WLC's which has some cool application identification/prioritization/filtering potential.

RE: End of Sale/End of Life Announcement on WiSMs
We hit the same issue here, we have 7 WiSM 1s and 3 WiSM 2s. I had just finally gotten away from a mixed code environment this past summer after putting the last 1010s out to pasture and now there's this. On our end we're working to fund replacing the WiSM 1s with WiSM 2s this summer, fingers crossed that will work out.

RE: [WIRELESS-LAN] Wireless only dorms, advice?
We purchased a few older apartment buildings which we converted to dorms and are doing wireless only in them. For the wireless we’re using Cisco 1142i and put one per apartment (some apartments are 2 beds, some are 4). As mentioned you definitely want to do PoE on the switches to provide better power visibility and have a good UPS. Since you’re going Cisco as well I’d suggest N+N controller redundancy as this will be their only network connectivity. If I were doing it now I’d go with a 3500 series for CleanAir, but that wasn’t available at the time. The only issue we’ve really ran into are gaming systems which wanted to use lower rates or couldn’t handle our captive portal authentication. Also starting in the Fall in our other residence halls we shut down all wired jacks prior to move in and only activated them upon request (no charge). All the dorms have 802.11n (mostly Cisco 3502i) installed in the hallway (densely) with the exception of a handful with APs in the rooms. I created a couple web-forms for the students to use. One activates the port + creates an 802.1x exception for a gaming device (known gaming OUIs), the other just activates the port for computer usage. While we have had a lot of gaming device activations, we have seen very few activations for computer usage. So as such it seems that our users have pretty much gone wi-fi only for their computers and are just using the wired ports for gaming at this point. But personally if I were in charge of new construction I would still want one cabled drop in addition to the AP in the room and would do activations upon request as Philippe mentioned.

I pretty much second Rick’s comments. We also don’t have wireless-only dorms yet, but the next one will have much less wire than our existing ones. One AP per suite is what we’ve done, but you have to also consider non-RF placement issues – vandalism concerns, maintenance access and residents complaining about blinky lights above their beds. Does the architect have issue with visible APs? If the APs are above ceiling / behind walls, do indeed check the materials and placement of ventilation ducts. Also, plan on PoE switches (and UPSes?) so power-cycling capability and visibility into the gear are improved. Keep in mind that the tiling of 2.4 GHz and 5 GHz doesn’t have to be the same, nor power levels, since the number of non-overlapping channels differs. I’d try to find as many carrots as possible to steer people to 5 GHz. 2.4 GHz is a pain, with game console controllers, microwaves and number of other consumer devices adding to the lack of channels. Depending on your vendor, having a good ability to sniff the air / do spectrum analysis can be helpful in figuring out whether a wing just lost connectivity due to a microwave, misbehaving AP or rogue AP. Other design decisions – do you plan to support broadcast/multicast discovery (wireless printers, time capsules etc.) or legacy devices that require low data rates (i.e. Nintendo).

Sara, We have not moved that way but are looking at implementing wireless in the dorms. We have decided to factor in several things in determining the density of wireless. You'll need to consider the fact that students are coming in with 3-4 wireless devices per person these days with at least a couple being used simultaneously. You'll also want to factor in the residence hall layouts. We've determined that we'll probably need to place at least one per suite. This is due both to multiple devices per user but also due to construction material and layout of the suites. If you want to take full advantage of 802.11N technology you'll also want to design based on 5GHz coverage with also reduces your coverage area.

RE: Interference in dorms.
Currently we're addressing this issue by installing the 3500 series Cisco Clean Air Access Points in all of our dorms and increasing the number of APs in the dorms while we do it. These access points do interference detection and will map it in Cisco WCS. I have a feeling it's probably going to look pretty scary once the students move back in, but with the ability to see what's causing the interference we can start better addressing it and educating our users. Also by deploying more APs we're hoping that more devices will use 5ghz instead of 2.4.

I am curious about how any of you guys have addressed this problem and informed the students of these potential interferences. Have any of you added a section to orientation that discusses the problem of interference and did it have good results.

No clues at all. But, the reports still stream in at a rate of 3-4/week with none of them resolved. Started having the problem with the 6.0.199.4 code and it persists with the 7.0.98.0 code that I am now running (at Cisco's request; it has been rock solid as far as I can tell). I thought I had it narrowed down a while back, but maybe not. We have seen times when a machines fails to get an ARP entry even after getting a good DHCP address. Obviously, no traffic ever went to or from the device with this entry missing. It was easy to duplicate too. When a machine got into this state, it would stay in it as long as it was associated with an AP on one controller. When it went to another controller (not via a roam, but with a new association) it would be fine. When it came back under the control of the original controller, it would have the problem again, even several days later. It could only be cured by rebooting the WiSM controller. This seems to have gone away with the 7.0.98.0 code though. I think my current problem, and yours is not related to the missing ARP problem.

RE: [WIRELESS-LAN] Cisco WLC code
I would recommend waiting for the 7.x MR1 code. We currently have 7 WiSMs and use webauth with an external webserver and encountered massive problems with the 7.0.98.0. When there were a lot of webauth logins on a WiSM it would become unresponsive over its management interface and thus would not properly process new logins and you couldn't remotely connect to it either. This is a bug that was fixed in 7.0.98.209 (ES release). That ES release was rock solid for months and now I've been running 7.0.114.92 (beta for MR1) for weeks without issue. So I would definitely recommend 7.x MR1, but I would not go for 7.0.98.0 since MR1 is right around the corner and fixes so many bugs.

With more than 200 plus controllers I haven't seen any issue. However I did asked about going to 7.x code and was told to wait till next maintenance release that should arrive in couple of weeks (2nd week of April ). Interestingly I was told the exact opposite, ask TAC not the AM or SE.

The 4402 has had nagging problems with webauth off and on for as long as I remember. We're presently having trouble on 5.2.193.0, which I thought was good. One flavor is that the login page doesn't redirect properly--the WLC fqdn shows in the browser's url window but the browser doesn't go there. Typing the url as https://x.x.x.x/login.html works for them, even though the client's DNS resolves the address properly. The other flavor is the login page appears, but doesn't work--the traffic doesn't make it to the Access Control Server or appear in the ACS logs. This will happen to one person while several others have no problem. A day or two later, the problem person's login works great and someone else has trouble. I've seen several bug reports on these. Anyway, the new WLC came with 6.0.199.4. I asked TAC what load they recommended and the answer was that I should really ask my account manager or vendor, but they would use 7.0.98.0. Would 7.0.98.0 be a good load to go to, and does webauth work better with that load?

RE: [WIRELESS-LAN] Any experiences with Cisco 3500-series CleanAir access points?
I've deployed 20 of the Cisco 3500i access points so far for testing and my early experience was mixed with them, but it's starting to look up. The first issue is that you have to run version 7 code, since I'm running WiSMs this mean moving two (for redundancy) 150 AP controllers over to the code. I initially upgraded some 1142s to the new code level as well to get full use out of the controller. However, within about a month I ran into an issue where the management port became unresponsive. I had this occur another two times (almost always 4 weeks into it) before TAC nailed it down to a bug which occurs when using webauth for authentication. Now I'm running an ES release with a fix until MR1 comes out next month, and for the time being I only have the 3500i APs on the controller, I moved the others back to a version 6 controller. With that said I've been running the ES code for 10 weeks with no problems now. I find that the CleanAccess spectrum analysis is very useful in dorms where there's lots of RF interference from devices the students bring in and it has helped save time with troubleshooting issues, however I haven't found it as useful in academic buildings where the environment is more controlled. Another thing with CleanAccess is that to fully utilize it you really need to have a MSE appliance, the reporting in WCS is anemic without one to store historical and detailed data. However, with the combination of WCS and MSE I really like the solution. As long as my test with the MR1 of WLC 7 code goes well our plan is to upgrade all our dorms from 1131s to 3500is this summer.

Does anyone have any experiences with the Cisco 3500-series CleanAir access points? We have a small project (about 40 access points) coming up and I'm thinking about deploying these as a pilot instead of the 1142s that we would normally deploy. I've discussed this will one of my people who handles our wireless deployments (Art Ripley) and he thinks we should. For background, we have most of the campus covered in wireless and a couple of years ago we started deploying for performance instead of coverage (more access points per square foot). We have nine Cisco WLCs (a mix of 4404-100s and 5508s) and a mix of 1131 and 1142 access points. We do not use WCS. Instead, we (Nathan Broome and I) have developed our own wireless management software. This has worked well for us but I'm wondering if I should move to an off-the-shelf package when deploying the 3500s. Any thoughts on this? I've arranged a meeting with our local Cisco sales office next week and this will be one of the topics I want to discuss.
