Hi,

tim.johnson@uss.co.uk — Tue, 11 Apr 2017 13:04:07 GMT

Hi,

Do you think this would help us with TAC CASE 682047948 as we have been unable to work out why despite the idle timeout and session timeout being set to 8 hours - our Apple products are deauthenticated every 9 minutes by the controller.

We're stuck at this point so would really be grateful if you could advise on this please?

Thanks,

Tim

Hi Tim,

Salil Prabhu — Fri, 14 Apr 2017 19:31:00 GMT

Hi Tim,

Just had a brief look at TAC case, it is suspected you are affected by this bug - CSCvb97383 resolved already in 8.4.114.44.. If you can fill the form we can grant access.

regards, Salil

Thanks very much for looking

tim.johnson@uss.co.uk — Fri, 14 Apr 2017 20:25:11 GMT

Thanks very much for looking Salil!

I've already been granted access but we would like to clarify please - if we install this release in production would Cisco still support us?

This bug is currently holding up a major deployment so any advice you can give us would be gratefully received.

Thanks and have a good weekend,

Tim

Hi Tim,

Salil Prabhu — Mon, 17 Apr 2017 08:17:57 GMT

Hi Tim,

Both TAC and BU would support this. However when CCO post happens it is requested to work to migrate to official CCO release with a reasonable time to upgrade (scheduling maintenance windows /downtime etc)

regards, salil

CSCus02070 Flex Ap losing

sandjose_cisco — Tue, 18 Apr 2017 06:29:32 GMT

CSCus02070 Flex Ap losing Vlan Mapping and falling on default vlan

Any insight on when this would get fixed .

The workaround for the issue are little cumbersome

Also the 5500 have a limitation on the number of APs in flexconnect group , so having it done via Flex groups is not a viable solution

The current workaround is to

1)detect if there a mismatch in vlan-wlan maping

2)Push a template from PI

Hi,

The bug is in U state. If you do observe this issue for your customer, I would recommend to open a TAC case and provide the required information.

regards, Salil

Hi Salil,

Hi Salil,

Thanks for your help again. We seem to have had a more negative reply from TAC about levels of support. Could you please take a look at the case and put a note on with your recommendations?

Thanks again,

Tim

Here is what TAC have said:

My name is Mohammad, I am the escalation engineer of the Wireless team who is handling this request for you, Bayan reached out to me yesterday trying to get more information on this, and this is why I decided jump in and email you directly.

If the end customer decided to use the Beta version with no recommendations from Cisco TAC/BU, then it is to be done at their own risk, since the action was not recommended by TAC/BU in the first instance, then the end customer owns the decision to proceed, but Cisco are limited to troubleshoot the issue itself and any other issues that might appear after the upgrade.

The purpose of Beta images as I’m sure you will know, is so that we let our customers test it and we should still support them, but you need to be aware that these images might be affected by more bugs than the normal/CCO images.

In summary, you can ask our your end customer to upgrade if he wishes to, but we need to be specific to our main issue, in case any other problems they face, will require a TAC case to be opened since the upgrade was not upgraded through the TAC/BU recommendation."

Hi Tim,

Hi Tim,

Sure. Let us address this with email..

Thanks Salil.

My email address won't be on the case because it is being managed by our outsourcer. Can you put a note on the case for them all to see please?

Thanks,

Tim

Has there been any reports of

Genesis IT — Wed, 19 Apr 2017 16:50:42 GMT

Has there been any reports of issues with 7925g wifi phones and one-way audio or random re-registration with this code? We installed this last night per TAC recommendation (due to Aeroscout RFID tags not showing with 3802 APs) and this morning we're getting flooded with reports of the 7925g phones having problems.

To note, we didn't have the issues prior to this upgrade when we were running 8.3.112.0.

We rolled back from this beta

Genesis IT — Thu, 20 Apr 2017 14:30:10 GMT

We rolled back from this beta code last night due to the 7925g phones randomly losing SCCP communication. After going back to 8.3.112.0 these phones are now stable again.

Interesting. I'll test this

kdavison007 — Thu, 20 Apr 2017 15:19:34 GMT

Interesting. I'll test this in our environment too. I have one of our controllers running 8.3.112 with 7925g phones. We also use Aeroscout/Stanley tags.

I installed latest 8.3/beta

Christian S. — Tue, 02 May 2017 12:07:57 GMT

I installed latest 8.3/beta (coming from 8.2) in my prod environment and found an error displaying AP capabilities with 1262 (we still have a lot of them):

Model / Domain

AIR-LAP1262N-E-K9 / 802.11bg:-E 802.11a:-E

Max Capabilities

No Radio 2.4GHz & 5GHz

Spatial Streams : 0 (2.4GHz), 0 (5.0GHz)

Max. Data Rate : 0 Mbps(2.4GHz), 0 Mbps(5.0GHz)

Clients have interesting connectivity prints:

Connection Rates
AP Max Configured 54 Mbps
Client Max Capability 72 Mbps
Client Actual Rate 65 Mbps

Another one:

Additionally, there is a space missing in this syslog message before mac-addr:

%APF-3-PREAUTH_FAILURE: [PA]apf_80211.c:13583 There is no PMK cache entry for cliente4:a7:a0:xx:xx:xx. Can't do preauth

Also, where can suggestions for improvements be sent to?

There is another bug, at

Christian S. — Tue, 09 May 2017 04:15:14 GMT

There is another bug, at least in my environment, which wasn't there with 8.2.

Every time the DCA algorithm ran the same process crashes after it finished channel changes. The crash doesn't influence the cluster or traffic, it just happens with 8.3 and it happens always. Maybe it's related to the false information collected from the 1262 APs?

Hi Christian

Javier Contreras — Tue, 09 May 2017 07:24:12 GMT

Hi Christian

check the wlc uptime, it should not be changing. This is quite probably CSCvd81902, which is fixed on next code refresh

(no impact)

regards

Hi Javier,

Christian S. — Tue, 09 May 2017 07:35:24 GMT

Hi Javier,

thank you for your reply. Do you mean uptime on wlc landing page? This is counting up as expected: Up Time 8 days, 1 hours, 39 minutes

I'll wait for the next code refresh and come back with new findings if it's ok for you?

Regards,

Christian
