Hi Javier,

Leo Laohoo — Fri, 20 Jan 2017 00:32:53 GMT

Hi Javier,

Will CSCvc57427 be addressed with this release?

Also will https://bst

patoberli — Fri, 20 Jan 2017 12:49:54 GMT

Also will https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvc46666 be addressed?

Hi

Javier Contreras — Fri, 20 Jan 2017 13:17:35 GMT

not planned for MR5 at this time (no fix ready yet)

The bug is on investigation phase, there was a debug image provided, plus some debugs pending, development is on hold waiting for that data.

regards

Hi

Javier Contreras — Fri, 20 Jan 2017 13:20:02 GMT

There is no fix available at this time, development is working on it, initial evaluation points to a leak related to AAA override function. if the fix is ready for the time window for MR5, 8.4, 8.3, we will try to include it

regards

Ok thanks, opened a TAC

patoberli — Fri, 20 Jan 2017 13:26:24 GMT

Ok thanks, opened a TAC yesterday for this issue (that bugid is not mine) as we also have this issue with our new 2800 models. Working fine with 2700 and 3700 with 80 MHz channels and the same test client.

But yeah, maybe it's also an Intel issue (which I really don't hope, as my clients are unmanaged).

ok... please let TAC know if

Javier Contreras — Fri, 20 Jan 2017 13:30:35 GMT

ok... please let TAC know if a debug image is possible. you can send me the case ID on email, so my colleague working on this issue can check it.

For intel, for all of their 11ac cards, it is extremely recommended to load the 19.20.3 bundle, as it has important fixes

regards

Damn, that is my next step

patoberli — Fri, 20 Jan 2017 13:48:12 GMT

Damn, that is my next step actually that I should test. But I couldn't do that with our users, as those are mostly "external" clients where I can't do anything.

Interestingly it works fine with the older 802.11AC models (2700, 3700 with 80 MHz channel).

Will send you an email with the with the TAC. I might be able to install a debug image, but on my old and now unused 5508 controller. The live network (with the bug) is on a 5520 controller though.

[edit]

clarified controllers.

Thanks, Javier.

ilja.sas — Tue, 24 Jan 2017 15:08:23 GMT

Javier,

We seem to experience CSCvc32706 with 2800 Series AP's.

They do not see their neighbor AP's even though they are a few meters apart.

DCA and TPC do not work properly due to this.
Out of 135 AP's, 90 are on channel 36 and all run TXpower level 1.

Any suggestions for a workaround other then manual channel and power assignments?

Hi

Javier Contreras — Tue, 24 Jan 2017 15:35:26 GMT

sorry, no workaround. You can use either 8.2MR4Esc (through TAC), or load this interim 8.2MR5, which already has the fix

regards

We managed to get RRM running

ilja.sas — Thu, 26 Jan 2017 12:56:16 GMT

We managed to get RRM running properly again by rebooting all AP.

They now see their neighbor AP's and can make TPC and DCA calculations.

Any idea if the issue can suddenly reappear?

Hi

Javier Contreras — Thu, 26 Jan 2017 14:16:11 GMT

yes, this is socket error on the control component for the radio, if you reload it would recover, but the error may happen again

the only way to prevent this, is to run a fixed code

regards

Hi Javier,

SupportAC — Tue, 31 Jan 2017 08:35:23 GMT

Hi Javier,

We have opened a TAC case, because it seems we are sufering CSCvb61023 DHCP option 82. We are using an escalation version 8.1.131.34, this version fixes CSCva95121 Stale IP route left on Flex AP config if booting up in standalone mode. do you know if version 8.2MR5 will include both fixes?

Cisco TAC told me the following:

"till now there is no clear ETA but we are pushing for the fix to be included on 8.2MR5 CCO release which should be this February"

Our end customer is a very important ISP in spain, and they are having a lot of problems with WLC bugs since they deployed EoGRE

Also TAC told me that both fixes will be included in release 8.4, this version will be avalaible at the end of February too.

wich version do you recommend?

thank you very much for your help

Will MR5 fix the bug

Billy Tsang — Sun, 05 Feb 2017 14:22:13 GMT

Will MR5 fix the bug CSCut39733, thanks.

Hi Billy

Javier Contreras — Sun, 05 Feb 2017 15:54:57 GMT

Hi Billy

CSCut39733 has been fixed since 8.2.100.0, so yes, included on this release

regards

Hi

Javier Contreras — Sun, 05 Feb 2017 15:57:18 GMT

At this time, this bug is planned to go into 8.2MR6, 8.4, and 8.3MR2

The fix arrived a bit late into 8.2MR5 program, so missed this release window. We can include in 8.2 after MR5 is posted, please ask TAC to reach out to me

8.4 is a new feature release, so if what you need is a bug fix, it is not the best candidate, unless you also need one of the new HW or SW features included

regards

Hello Javier,

betheric63 — Mon, 06 Feb 2017 15:32:46 GMT

Hello Javier,

We loaded 8.2.141.10 per TAC suggestion.

We had the issue on our(WLC 5520) 2800s bug (CSCvc32706) When on 8.3.104.78.

This seemed to fix our issues, however we noticed the APs started reporting Half Duplex to the switch But showing Full in GUI, filling my switch logs with Duplex-Mismatch errors.

Shutting the port down and bringing it back up seems to correct on my 3750X sw. But on a few legacy switches won't clear the error.

Is this a bug or Caveat to the 8.2.141.10? Have you seen this before.

We have a TAC case opened, but Figured I would ask here.

Yes, ports configured to Auto-Neg. the Speed and Duplex.

TKIP support req'd.

Any input appreciated.

Update on my case. With my

patoberli — Thu, 09 Feb 2017 14:23:55 GMT

Update on my case. With my two test clients (Windows 7 x64 + Intel 8260AC / Windows 10 x64 + Intel 7265AC) it was an Intel driver issue, fixed in the latest version 19.20.3 (Win 7) and 19.30 (Win 10). With those drivers the packetloss disappeared.

But we also found a new issue, for which a new TAC will be opened, if the 2800 AP is set to 80 MHz and a channel order which isn't from low to high (for example DFS has chosen 40,36,44,48), then the Intel 8260AC has a really low performance and only connects with 20 MHz speeds. Once the channels were manually reordered (by manually configuring the channels and selecting 36 is the primary), the client connected with 80 MHz.

It's yet unclear if this is an Intel issue or 2800 one, as we don't have it on 3700 and 2700 models, where DFS also tends to order the channels like this. I haven't yet received the new TAC number.

Definitely if using Intel's

Aaron — Thu, 09 Feb 2017 15:59:17 GMT

Definitely if using Intel's 11ac adapters (726x/826x), you will want to be sure to use current drivers (at least 19.20.3 bundle.)

That said, we have our share of just-fixed issues on our (2800/3800) side as well. We've recently fixed several bugs that revolve around channel width changes (e.g. CSCvc81491, fixed in 8.2.145.32, and I think another that I can't find right now.) So do run the latest 8.2 MR5 interim that you can get, then upgrade to CCO 8.2 MR5 once it releases (within the next several weeks.)

If you should hit some interop issue between our APs and Intel adapters that we can't figure out, then be sure that you have a TAC case open, and be sure that TAC finds or files a corresponding bug. If you willing to capture OTA pcaps etc. we can bring in Intel as needed to resolve any lingering issues.

Cheers,

Aaron
