Bruce: "Too bad these features can't be enabled/disabled on a per-AP basis." You just nailed the essence of one of the big trade-offs of all that is gained with the thin wireless architecture. In many ways, the WiSM is the AP, and the APs have become antennas- the feature granularility of autonomous APs is greatly reduced, and often in ways that are counter-intuitive (at least to me).

Either way, the impact on connections is, as all Cisco caveats are, neatly tucked in the back of the Field Notices. I had this enabled on one controller to test its effectiveness, and it explains why I see the resets exclusively on the b/g radios of APs that actually hear rogues. Too bad these features can't be enabled/disabled on a per-AP basis.

See the attachment. RLDP actually resets the radio interface in order to associate to a rogue AP as a client and attempts to send a message through the rogue AP to see if it reaches the controller. This can take 30 seconds. Just a thought. -Jeff Legge Radford University From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[EMAIL PROTECTED] On Behalf Of Manoj Abeysekera Sent: Wednesday, October 08, 2008 2:55 PM To: [email protected] Subject: Re: [WIRELESS-LAN] Cisco Wireless Controller Mike, We run 4.2.130. I was told by Cisco Engineer to downgrade to this version as we had a nightmare with 5.x. However we still get Clients disconnected at random intervals(Radio seems to reset somehow forcing clients to roam to nearby LAP's). Cisco has no clue and i wonder why not many people have called them yet. WLC's 4404 AP's 1230 Open Network Let me know if you find a cure.. Good Luck! Manoj American U. Mike King <[EMAIL PROTECTED]> Sent by: The EDUCAUSE Wireless Issues Constituent Group Listserv <[email protected]> 10/08/2008 02:44 PM Please respond to The EDUCAUSE Wireless Issues Constituent Group Listserv <[email protected]> To [email protected] cc Subject [WIRELESS-LAN] Cisco Wireless Controller So Cisco LWAPP people, Currently we're on 4.1.185.0 <http://4.1.185.0/> . It's a 4402 controller, with 1131AG access points. Anyone made the leap to one of the 4.2, 5.0 , or 5.1 trains without seriously regretting it? We've had some random disconnects with clients. It's pretty common, happening to most all users. We're running WPA-PSK, so it's not an 802.1x issue. Before we involve TAC, we figured we should upgrade to a new code train.
