If you don't use WZC, what supplicant is used in your client base?

Clients who use WZC (why anyone would is beyond me) will still be able to connect without issue, as it is considered "optional" on the WLAN. _____ Charles Bisel IT Operations Bayer Business and Technology Services LLC 100 Bayer Road Pittsburgh, PA 15205 PHONE 412.778.1268 FAX 412.778.1299 EMAIL <mailto:charles.bi...@bayerbbs.com> charles.bi...@bayerbbs.com WEB <http://www.bayerus.com/> http://www.bayerus.com _____ "Johnson, Bruce T" <bjohns...@partners.org> Sent by: The EDUCAUSE Wireless Issues Constituent Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> 02/19/2009 11:20 AM Please respond to The EDUCAUSE Wireless Issues Constituent Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> To WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU cc Subject Re: [WIRELESS-LAN] Transitioning to dot1x Charles, CCKM is supplicant-dependent (via Intel PROSet or other hardware client utility).

The default for dot1x is every 30 minutes. You may want to make this value larger. The User Idle Timeout will do the same thing, but most laptops generate enough incidental traffic to keep the idle timer open. Smaller form factors may not be as chatty. If its due to roaming, you may want to use WPA2/AES rather than TKIP, as this supports Proactive Key Caching. Do a "sh pmk-cache all" on the controllers to verify. Bruce T.

We don't have trouble getting folks configured and connected. Just after that we get complaints of 'getting kicked off' and was wondering if anyone else sees this sort of behavior. I suspect this mostly occurs during roams, but don't really have any hard data to back that up.

That being said- we had to say no more support for Windows 2000, 98, Me, etc. Same on Mac- a minimum OS was required. We avoided other EAP types that require a per-device cert, and officially only support the native Windows supplicant and native Mac supplicants for ease of support. We also chose to stick with our "classic" Cisco ACS 3.3.3 boxes- simply because we already had them, and they do a rock-solid job as well as provide decent logs (important). They also talk well with our AD credential store for user credential verification. We have found the ID Engines- now Cloudpath- supplicant configuration tool to be key to our success in that we can point users to a "help SSID" for initial client config, or self-remediation later if they hose their settings. Very powerful- but again, requires that users use Windows and Mac native supplicants and disable all of the ProSet, Broadcom, Toshiba, etc wireless utilities. We also provide basic settings in document form for advanced users that won't give up their third party utilities, and for Linux/handheld users that we can't auto-configure. Driver issues will manifest themselves more on a dot1x network- the rule of thumb is to keep them updated, or as a minimum, update before going to 1x. This often helps windows machines when nothing else will. On the Macintosh side, unfortunately it seems that even minor code updates can wreak havoc on the wireless driver and 1x utility- but once you get past whatever new curve ball Apple throws you, they work very reliably. As for AD machines on wireless- is a whole different ballgame. Officially, we do not support AD machines over our wireless networks, but if the machine name is the same as the userID, it will work in our environment. Then there's loaner laptops. and NAC integration. and how to handle visitors on the network. All have solutions, but you may have to get creative. We have 2000+ APs, 12 WiSMs, and typically see 5,500-6,000 users at peak on our wireless networks daily. In the dorms (100% covered) wired usage has fallen to less than 20% of what it was 2 years ago, and has become mostly an "entertainment" network. -Lee Lee H.

We hope to shut down the wide open non-authenticated ssid this summer. We've had numerous communications sent out and we always seem to get responses that the new dot1x network is slower than the old and that people have trouble maintaining a connection. I am curious as to how other schools approach this. Is it possible that a dot1x only network magnifies trouble areas of wireless coverage? Or is it that the dot1x network is more sensitive to client issues. Or could it be something I had not mentioned. BTW, we are a Cisco WISM/LWAPP shop. Thanks!
