CSCsr40109 Bug Details http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBu gDetails&bugId=CSCsl51486&from=summary
Mobility announcements not sent after an upgrade when wrong version Symptom: When a mobile station roams from an AP joined to one controller, to an AP joined to another controller, the client may suffer a lack of data connectivity for a period as long as the configured user idle timeout. "debug mobility handoff enable" output shows that, after the roam event, the WLC to which the client has roamed does not send the MobileAnnounce message to the WLC from which the client had roamed. Conditions: Multiple WLCs in the same mobility group, running 4.2.112.0. The WLCs had all been upgraded from 4.1.185.0, and then had not been rebooted again. Workaround: There are 2 workarounds for this issue, 1) Delete the mobility members from the configuration and re-add them. 2) After upgrading all WLCs to 4.2.112.0, reboot them all once more.

Lee, Are you using GLBP? I recently had an issue with clients roaming from one AP to another AP on a different controller, but in the same mobility group. After a week or so of providing Cisco with logs and configs I was issued the following: Bugs CSCsv21441 and CSCsv21464 have been filed on the GLBP issue. As a work around I was instructed to use the router's actual ip address instead of the GLBP virtual address for the default gateway on the client interfaces.

We have an open TAC case right now, but so far no response to what is becoming a very disruptive condition. It seems that any OS is impacted (Linux, Mac, Windows) but only on our secure 802.1x network- open networks not affected- in that if you roam from one AP to another your session breaks. Seems worse on APs on different controllers, though everything is in the same mobility group. We've made no system changes and did not have this problem a week ago. Weird stuff- debug is so convoluted and chattey on a busy controller that it's hard to extract any value in this case Lee Badman ________________________________ From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[EMAIL PROTECTED] On Behalf Of Bentley, Douglas Sent: Thursday, October 30, 2008 11:14 AM To: [email protected] Subject: Re: [WIRELESS-LAN] Windows Wireless Clients- strange behavior after recent Windows Updates? Yes, Cisco for us. 2 6509E with 6 WiSMs (3x3) and 2 4404-100s in our test core. We just moved to 4.2.130. I need to perform more testing with this code in place. We are using open and WPA with web authentication as well as WPA2/AES. Douglas R.

We are so far finding that just changing network selection (go to another network then come back) or disconnect/reconnect, or reboot, or similar does tend to fix it. Lee H.

I have had reports from one user that sound very similar to your last item. They say they can connect in one location, but when they move they have no connectivity. If they move back they are online again. I am still waiting for the user to contact me with more details about their device, have you found a fix/workaround for this? We run mostly Meru with BlueSocket and nothing special like 802.1x.

Wondering if anyone else is feeling this effect after the recent spate of updates to XP and Vista machines- our Mac. Linux, and handheld users seem to be immune and we have had no configuration changes in our Cisco LWAPP environment of late, and the condition has also been noted on at least two staff machines in their home networks: - Machines coming out of sleep, hibernation, screen saver, etc have an IP address, but can ping nothing (but themselves) - Wireless sniffing showed one user was simply generating null data frames (likely 802.11 power save related) - Or- user is good and functional on one AP, but cannot move to an AP on another controller- same symptoms described above. Again, non-Windows users have no issue Is this ringing bells for anyone? Mostly, this seems to be very recent. I know for sure that Windows XP SP3 was not kind to one of my own PCs- after the reboot it came up with unrecognized hardware (sound card) and drastic changes were made to my wireless adapter including my 802.1x profile being changed. -Lee Lee H.
