Hi Gertjan,

A tac engineer today confirmed with BU that the fix is not even in 8.5.161.5.

I was told to wait for 8.10mr3 which supposedly has a fix for this bug. We 
can’t go above 8.5 because of presence of old Aps (3500, 3600) so we are stuck 
😐.

We have another pair of 8540 and I plan to upgrade it to 8.10mr3 and then 
migrate all 3800’s to it. Hopefully that will fix the issue for us.

Hi Jeff,

 

CSCvt22353 is related to CSCvn66715 : Cisco 3800 AP stops passing traffic under 
client with Intel NIC 8260/8265 load in MU-MIMO deployment

 

8.6.161.5 is the latest recommended version without the fix for CSCvq90572 : 
Receive throughput degrades for 2800/3800/4800/1560 - AP fails to send block

We had to upgrade to 8.5.161.4 due to issues we experienced with the 8.5.161.0. 
We had a problem where an AP would allow clients to associate but they would 
not pass traffic. The new code, as recommended by TAC appears to have fixed the 
issue, we have been running it for 36 days. But we won’t know for sure until we 
get our normal client levels back with the return of students to campus.

Hello everyone,

 

We are running code 8.5.135.0 on one of our WLC 8540 pair. We can’t go past 8.5 
because of presence of 3500 and 3600 model Aps which are not supported beyond 
code 8.5.

 

What code you are running in 8.5 train and how satisfied you are with it?

 

Is anyone running code 8.5.161.0 recommended by Cisco TAC? How stable is it? 
Have you encountered any major issues in your environment?

 

Has anyone tried 8.5.16.4 (escalation code)?

 

Thanks in advance for your responses 😊

RE: Cisco WLC Stable code in 8.5 train

2020-06-26 Thread Sullivan, Don

We are running 8.5.161.0 and have experienced no issues. We did not run the 
WLAN poller before the upgrade.

Thanks Bryn for the reply.

Just curious, did you run the WLAN Poller before upgrade and were there any Aps 
identified having flash corruption issue?

We have been running 8.5.161.0 for the last 30 days without incident.

We are in the same situation as you with regards to the 3500/3600 models 
restricting us going any higher.

Hello everyone,

We are running code 8.5.135.0 on one of our WLC 8540 pair. We can’t go past 8.5 
because of presence of 3500 and 3600 model Aps which are not supported beyond 
code 8.5.

What code you are running in 8.5 train and how satisfied you are with it?

Is anyone running code 8.5.161.0 recommended by Cisco TAC? How stable is it? 
Have you encountered any major issues in your environment?

Has anyone tried 8.5.16.4 (escalation code)?

Thanks in advance for your responses 😊
