Hi Javier,
Will CSCvc57427 be addressed with this release?
01-20-2017 05:20 AM
Hi
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
01-22-2017 02:42 PM
Thanks, Javier.
01-20-2017 04:49 AM
Also will https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvc46666 be addressed?
01-20-2017 05:17 AM
Hi
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
01-20-2017 05:26 AM
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).
01-20-2017 05:30 AM
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
01-20-2017 05:48 AM
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.
02-09-2017 06:23 AM
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.
02-09-2017 07:59 AM
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
02-09-2017 08:32 AM
Thanks for the update. Maybe this bug is the issue I have, I will probably soon see.
This "new" channel ordering issue is with the latest drivers. Luckily I'm in no hurry to replace my old APs with the 2800 models, they can stay a few more weeks in the box, until 8.2 MR5 is released.
01-24-2017 07:08 AM
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?
01-24-2017 07:35 AM
Hi
sorry, no workaround. You can use either 8.2MR4Esc (through TAC), or load this interim 8.2MR5, which already has the fix
regards
01-26-2017 04:56 AM
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?
