RE: Controlling Bonjour Zones
Hi Peter, Thanks for your response, it seems we are in a pretty similar state tech wise though you have a lot more TV's to deal with. Though we have not upgraded production to 7.4 (using on our dev controller) so went straight to local AP group for the one request we couldn't hold as it was required for teaching. Everyone else we have asked to be patient and so far that's working. The local AP group is a real pain though, we already have enough of them to deal with which is another issue entirely. Yeah the lack of battery in the ATV is a pain, we will probably do the same and connect them to wired or use a WPA2-PSK rather than dot1x. After a discussion with our Cisco reps, the good news is that 7.5 has location based improvements which looks pretty good for what we want to achieve here. I'm not sure what detail I can provide apart from (something relevant is coming) so if you are interested get in contact with your local rep.

Like you we found the bonjour gateway features worked, but did not provide location control. In some cases our academics have multiple AppleTV's in the one location and don't mind that they are all available. In other locations, they only want to see the local Apple TV, so we have an ssid advertised with a name like ATV-P512 to let them know this is the apple tv for Building P room 512. This is a bit of a pain as we also have to create an ap-group for each apple tv. We are using 802.1x and found that if the ATV is powered off, it does not store the time and has issues accepting a certificate. For this reason we connect the AppleTV using the wired port, on the same vlan that the ssid terminates on. We actually had to turn off the bonjour gateway feature for these networks to achieve our goal. While this is not an ideal solution, it achieves the outcome we require. Peter.

I know other vendors have similar workaround features and am interested see how people have gone with it, keen to hear from users of other vendors as well. So far it all seems to work as advertised, was pretty easy setup with good control over what services you advertise. However I find there to be a lack of location control, and would like to know if anyone has implemented ways to control the location where the advertisements go. For something like this we'd like to restrict the advertisements to location by building/level/room/AP, it will help it scale better for users devices when scrolling through the list of available devices to connect to like an Apple TV. Users in building 1 don't need to see an Apple TV in a meeting room in building 2. Using separate SSID's is also not really a scalable solution... though does work of course with a dedicated subnet and multicast enabled. We currently don't have building based networks, which would be one way to control advertisements. This is something we are planning, but are a while off yet, also the ability to go more granular than just buildings would be useful. I've started a conversation with our local Cisco office, but am interested see what others may have done or believe could be useful for this.

We use our open SSID for clients to register non-802.1X devices or provision 802.1X with Cloudpath XpressConnect. Unregistered devices are captured using a combination of DHCP DNS redirection. With our Aruba wireless, we redirect all DNS traffic to our captive portal DNS server, only allowing the outside access needed to provision the clients. You need a user account to register devices.

My only suggestion would be to be careful not to err on the side of suck. We did that for a while, but I really had a problem offering a service that sucks. It also struck me that it did not offer a welcoming environment to our visitors. I agree that it is important to have incentives that gently steer non-guests towards the 802.1x service. Logging into a web page each time provides built in incentive. We also found that that limiting the time they are allowed to use the guest service, to the time it takes to get a temporary ID that can get them on 802.1x was the ideal, rather than cripple the service itself so that it was a frustrating experience for those who used it. We usually capture a phone number to cover attribution. The other advantage of the open SSID is that it is a good temporary solution for someone who has issues configuring their device for 1x. Some devices have difficulties (even using Xpressconnect). And when you think about it, maybe it isn't the end of the world if someone who can do 802.1x uses an open SSID.

RE: RF interference from 802.11
Putting on my ex-physicist hat for a moment... Without knowing what the experiment is and how it and its room are shielded, it's hard to tell. That being said, giving the concerned faculty member the specs (power level, gain, frequencies) and offering to reduce the power or turn off one of the radios, or do a Let's try it out, and we'll turn it off if it does interfere? offer might work. It might also help to explain that enterprise Wi-Fi devices are pretty clean and do typically not radiate appreciably outside of their intended frequencies. Give them all the technical data necessary for them to make the judgment, and do it with some olive branches to avoid the impression that IT is running over the needs or desires of faculty but rather wants to work with them. Considering that cordless phones and microwave ovens among others will cause just as much if not more interference on 2.4 GHz than a Wi-Fi AP, it seems to me that unless their surroundings have been specifically sanitized you'd not be introducing anything new, which could also be a point to make.

RE: RF interference from 802.11
Because APs are a source of heat and potentially light, we have had requests from our Physics and Astronomy Departments that APs not be placed in certain temperature controlled and dark areas. Some researchers on the medical campus have also inquired about the effects of APs in their vicinity, but have not formally requested no installation or removal yet, so I think it is potentially a problem depending on the requirements of any particular research area. -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Julian Y Koh Sent: Tuesday, June 04, 2013 5:23 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] RF interference from 802.11 Has anyone had to deal with researchers claiming that 802.11 RF causes interference with their laboratory experiments and apparatus?

Re: [WIRELESS-LAN] RF interference from 802.11
We faced the same situation in a building with multiple tenants. Researchers with labs didn't want wireless because they were concerned that it would interfere with their equipment (They didn't want to spend the money to shield the equipment) while people in the office spaces wanted it. The occupants were from two different colleges, so we told them they needed to come up with a formal agreement on where they wanted wireless. They never did, and I think we ended up putting wireless in the office spaces eventually.

Re: [WIRELESS-LAN] RF interference from 802.11
We had to deal with this also. The location in question was newly constructed with shielding to prevent interference from the outside world to their very sensitive equipment. The thing is, they requested an AP in that area that can be turned on/off at their discretion. This goes against our policy but we made an exception and installed an AP that they could unplug. That AP's uptime (101d) matches the controllers uptime. So either they have not run any test since then or they discovered no interference from wi-fi. My guess is no interference.

We're getting rumblings out of our Physics department - they are trying to prevent APs from getting installed in their area because of what they say are highly sensitive devices that will be adversely affected. My personal opinion iswell, I'll withhold that for now. Anyone gone through this?

Re: Non-802.1x devices on wireless...
We are removing our open SSID for sponsored guests (and students/faculty/staff non-802.1x supporting devices) Friday. It will be interesting to see what problems are generated. We have had three SSIDs: 802.1x, open for sponsored guests (mostly), and an open commercial provider. Sponsored guest may use 802.1x or open. Unsponsored guests use the commercial provider. Students/faculty/staff are supposed to use 802.1x, and mostly do (the open SSID's web-redirect had login timeouts that were bothersome from a user perspective). This spring the open sponsored guests network only had 0.47% of the client load -- most of those guests and not university. One goal has been to get the loosely affiliated guests onto the commercial provider and off the university's networks. So we end up with 802.1x, open commercial provider, and an open help/landing directing to one of the other two and offering configuration assistance. -- William C.

RE: [WIRELESS-LAN] Non-802.1x devices on wireless...
We have split non 802.1x devices into two categories. User devices like kindle's, and non-user/shared/infrastructure devices. We do not provide wireless network for user devices due to a combination security concerns and/or too much management required with solutions like hotspots, open networks, self registering etc. We have not seen a huge number of requests for this, so there's been no real need or push for us to develop a solution in this area. For the rest we do provide a network. These devices might be building monitoring tools (temperature etc), shared devices like PC's on mobile trolleys that get wheeled around and used by anyone. We provide a WPA2-PSK, don't broadcast, only IT staff can enter the PSK and the device also needs to be registered. There is only a handful of these... about 5. It may not be the most scalable solution but it certainly works for what our needs are at this stage. The mobile trolleys were a trial, we'd probably develop something around creating accounts in the dot1x space if that becomes common.

I seem to remember seeing some discussion a while ago about non 802.1x capable devices on wireless. We're a Cisco wireless shop, and currently run 2, about to be 3 (with the addition of eduroam) SSID's. Is anyone running a specific SSID for these non-802.1x capable devices? Perhaps using WEP and MAC address authentication? Feel free to contact me off list... I'm just trying to get some examples of best practice (or at least implemented practices) from other institutions. Respectfully, Danny Eaton Snr.
