Re: [WIRELESS-LAN] Disabling 802.11b speeds
Sorry to drum up an old thread, but I am contemplating disabling 802.11b. We have not had any users on 'b' in the last 6 months and are confident about turning it off. One question I do have for those of you that use Cisco controllers, is how are you turning 'b' off? I talked to a network consultant and they said to go into each WLAN and set the Radio Policy option to 802.11a/g Only and that would take care of it. It looks like most in this thread change the data rates to disabled under Wireless 802.11b/g/n Network. I am curious to know which method is better and what your settings look like. We are running code line 7.0 but will be upgrading to 7.2 soon if that makes a difference.

RE: [WIRELESS-LAN] Disabling 802.11b speeds
We only went with the option of turning off the data rates, so I can't attest to what your consultant is telling you, but the way we did it worked exactly as we intended. Here's a look at the settings from one of our controllers.

RE: [WIRELESS-LAN] Disabling 802.11b speeds
Unless something has changed then I understand this is the way to do it if you intend to use Band Select, as Band Select makes it mandatory for all bands/Radio Policies to be enabled. So you enable all Radio Policies (inc .11b), but disable the .11b speeds. From the footnotes of WLAN 'SSID Name' Advanced on the controller management GUI. 8. Band Select is configurable only when Radio Policy is set to 'All'. Thanks, Jezz.

Re: [WIRELESS-LAN] Disabling 802.11b speeds
Thanks for the quick responses. I like the idea of using client band select so I am going to go the same route as many of you and disable the specific data rates. Going to give Andy's config a try.

Large Environment Juniper RADIUS
Hi to both groups, apologies for cross-posting for some of you. Looking for targeted feedback from any large environments (10K + clients) using Juniper for RADIUS that are analogous to us: PEAP w/MS-CHAP v2, AD Auth, Cisco Wireless. Really only looking for feedback on RADIUS functionality, nothing else in the Juniper offerings. Specifically- - Satisfaction/disappointment- what do you like and not? - How long have you used Juniper? How long do you expect to keep going with them for RADIUS? - How robust do you find the reporting features? Anything not there that you rely on other sources to get? - If multiple boxes, how do you do central reporting? - What is your scaling/topology strategy? How many servers, and why? Bonus question: we occasionally get wild spates of misconfigured wireless devices that pound on our Cisco ACS boxes (visitors, passers by), and without client exclusion on the wired side can see what amounts to DOSing going on for our servers. Have you experienced this, and how did you overcome it? Please, no vendor calls as a result of this message:) Thanks- Lee Badman Syracuse University ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
Re: [WIRELESS-LAN] Disabling 802.11b speeds
Hi, We're looking into this, too. What's the best way to obtain data as to which clients are only 802.11b-capable on a Cisco environment? I do see a few connections at 802.11b data rates but we'd ideally like to know how many legacy devices out there that we have.
