RE: Cisco 8540 Code Recommendation, Based on Stability?

[Viou, Robert]

On release 8.10.151.0 we hit this bug 
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx97906/?rfs=iqvred and had to 
disable syslog output from AP's until able to upgrade to 8.10.162.0 as millions 
of log messages.
Otherwise we have had no issues with 8.10.151.0 code.

We have been running 8.10.151.0 in our standalone cluster with ~100 APs for 
about 2 months now and it has been running stable.

Hi all,

After a tumultuous series of code versions, awhile back we settled on 8.5.151.0 
and hung on to it like grim death because it was very, very reliable.

Given that 8.5 code goes end-of-support at end of 2021, combined with latest 
rounds of announced vulnerabilities, I'm looking for recommendations in the 
8.10 train based on wanting stability above all. We have 3800s and 3700s 
currently, likely to stay that way through the next academic year.

Has anyone found an 8.10. code version for the 8540 that supports the 3700 and 
3800 while providing good daily stability?

Thanks,

[Jason Mallon]

We have been running 8.10.151 on five HA pairs for over a year now without any 
code related issues.  There are currently somewhere between 9000 and 9500 APs 
ranging from 2700s to 9130s.  We were just made aware of bug CSCvx98176 by our 
SE, but have decided not to upgrade to 8.10.162 without seeing the bug.

The log “chatter: lat_client_add(422): Failed to add client” is documented in 
CSCvv78366. The release notes for 8.10.151 say that it is resolved, but it is 
not. From the troubleshooting I’ve done, even on MR5, it appears this bug is 
purely cosmetic. I have not had issues connecting to APs experiencing this bug 
when I have tested. The biggest issue with this bug is all the trash that is

Hello all,

We were struggling with this issue as well on version 8.10.130.0. We created a 
tac case (SR 690110031) last year but due to covid and lockdowns we couldn’t 
reproduce the issue. We only saw these issues on places where there was a lot 
of clients/roaming. On these ap’s the logs were filled with “chatter: 
lat_client_add(422): Failed to add client”. Not sure if this was related 
though. We only saw this issue on newer ap’s (2800/3800 and 9120’s).

No fix so far (and apparently not even in 8.10.151). Cisco pointed us to bug id 
CSCvv78719 and we had to disable MU-MIMO.
We weren’t able to verify this fix.

Not sure as yet as we have been too busy to get this over to TAC at the moment 
since we identified the problem and came across this bug ID at the end of last 
week. It’s certainly the closest match we can find.
We can see that most of our 2801 APs sit at around 30-50% memory utilisation, 
however around 6% of them (about 320) are currently above 60% which is unusual. 
These appear to be climbing steadily at around 3-4% per week as though there is 
a memory leak.
We first spotted this when we got reports from students in a residence saying 
they were connected to wifi but nothing was working. Looking at the AP it was 
sat at 95% memory utilisation. Rebooting the AP restored service. However, we 
then looked at nearby APs and could see them climbing as well. It doesn’t 
appear to be all our APs but some unknown subsection of them.
We only went to 8.10 as we had bought some 9105 APs.

[Rios, Hector J]

The log “chatter: lat_client_add(422): Failed to add client” is documented in 
CSCvv78366. The release notes for 8.10.151 say that it is resolved, but it is 
not. From the troubleshooting I’ve done, even on MR5, it appears this bug is 
purely cosmetic. I have not had issues connecting to APs experiencing this bug 
when I have tested. The biggest issue with this bug is all the trash that is 
generating.

Hello all,

We were struggling with this issue as well on version 8.10.130.0. We created a 
tac case (SR 690110031) last year but due to covid and lockdowns we couldn’t 
reproduce the issue. We only saw these issues on places where there was a lot 
of clients/roaming. On these ap’s the logs were filled with “chatter: 
lat_client_add(422): Failed to add client”. Not sure if this was related 
though. We only saw this issue on newer ap’s (2800/3800 and 9120’s).

No fix so far (and apparently not even in 8.10.151). Cisco pointed us to bug id 
CSCvv78719 and we had to disable MU-MIMO.
We weren’t able to verify this fix.

To follow up, Cisco TAC have put our problem down to the bug ID I mentioned 
below.
Their advice was to use the workaround of disabling DMS 11v option from the 
WLAN. They also advised disabling MU-MIMO.
We disabled DMS 11v, but we were certainly not going to disable MU-MIMO!
From our initial investigations it looks like disabling DMS 11v has solved the 
issue (but its early days) and we are told this bug will be fixed in 8.10.150

Hi all,

After a tumultuous series of code versions, awhile back we settled on 8.5.151.0 
and hung on to it like grim death because it was very, very reliable.

Given that 8.5 code goes end-of-support at end of 2021, combined with latest 
rounds of announced vulnerabilities, I’m looking for recommendations in the 
8.10 train based on wanting stability above all. We have 3800s and 3700s 
currently, likely to stay that way through the next academic year.

Has anyone found an 8.10. code version for the 8540 that supports the 3700 and 
3800 while providing good daily stability?

Note on code.  Cisco does run a very helpful EFT program for their code, and in 
most cases it is supported for production use. It is also supported directly by 
the Wireless BU, which is a plus.  They will post announcements on the Cisco 
community site, and once you’ve signed up, you’ll get future announcements as 
well.  Even if you are not interested in running the code, it’s helpful to see 
what fixes/issues are being addressed in the next MR release.

Here are the current EFT offerings that I’ve aware of.

These appear to be climbing steadily at around 3-4% per week as though there is 
a memory leak.
We first spotted this when we got reports from students in a residence saying 
they were connected to wifi but nothing was working. Looking at the AP it was 
sat at 95% memory utilisation. Rebooting the AP restored service. However, we 
then looked at nearby APs and could see them climbing as well. It doesn’t 
appear to be all our APs but some unknown subsection of them.
We only went to 8.10 as we had bought some 9105 APs.

That one’s interesting because it shows affected code is 8.5(140.0), and only

It’s a really annoying bug too as to the user they appear to be connected to 
Wi-Fi but they have no network activity at all. Also the APs seem fine from a 
monitoring perspective unless you are either carefully monitoring their memory 
usage, or they get so far out of memory that they appear to lose their 
registration with the controller.
As such, I really can’t recommend 8.10.151.

Hi all,



After a tumultuous series of code versions, awhile back we settled on 8.5.151.0 
and hung on to it like grim death because it was very, very reliable.



Given that 8.5 code goes end-of-support at end of 2021, combined with latest 
rounds of announced vulnerabilities, I’m looking for recommendations in the 
8.10 train based on wanting stability above all. We have 3800s and 3700s 
currently, likely to stay that way through the next academic year.



Has anyone found an 8.10. code version for the 8540 that supports the 3700 and 
3800 while providing good daily stability?

Lee,

 

I have one 8540 pair still on 8.5.151.0 – because it just works…

The other pair I had to upgraded due to many bugs/issues with the 702W and now 
have to support the 9105w, I’ve been running this 8540 pair on 8.10.130.9 since 
December and that has been working well with 9105W’s, 1815W, 2802, and 3702’s.

Jason,

Any possible tie to the iPhone and IPads issues being tied to iOS update?  
Looks like 14.6 officially dropped 5/24.

Subject: [EXTERNAL] [WIRELESS-LAN] Cisco 8540 Code Recommendation, Based on

Hi all,

After a tumultuous series of code versions, awhile back we settled on 8.5.151.0 
and hung on to it like grim death because it was very, very reliable.

Given that 8.5 code goes end-of-support at end of 2021, combined with latest 
rounds of announced vulnerabilities, I’m looking for recommendations in the 
8.10 train based on wanting stability above all. We have 3800s and 3700s 
currently, likely to stay that way through the next academic year.

Has anyone found an 8.10. code version for the 8540 that supports the 3700 and 
3800 while providing good daily stability?

Thanks,

We are on 8.10.142 on our 8540s and the majority of our APs are 2802i  as well. 
As per bug details, we should be affected too but haven't really noticed this 
being an issue.
I am interested to hear what comes out of the TAC case.

We are on 8.10.151 for the last couple of months here at Loughborough 
University in England. We think we are being hit quite badly by this bug:
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvp31778
with around 6% of our 2802i APs being currently affected.
It's a really annoying bug too as to the user they appear to be connected to 
Wi-Fi but they have no network activity at all. Also the APs seem fine from a 
monitoring perspective unless you are either carefully monitoring their memory 
usage, or they get so far out of memory that they appear to lose their 
registration with the controller.
As such, I really can't recommend 8.10.151.

Re: [WIRELESS-LAN] [EXTERNAL] [WIRELESS-LAN] Cisco 8540 Code Recommendation, Based on Stability?

[Jonathan Oakden]

Not sure as yet as we have been too busy to get this over to TAC at the moment 
since we identified the problem and came across this bug ID at the end of last 
week. It’s certainly the closest match we can find.
We can see that most of our 2801 APs sit at around 30-50% memory utilisation, 
however around 6% of them (about 320) are currently above 60% which is unusual. 
These appear to be climbing steadily at around 3-4% per week as though there is 
a memory leak.
We first spotted this when we got reports from students in a residence saying 
they were connected to wifi but nothing was working. Looking at the AP it was 
sat at 95% memory utilisation. Rebooting the AP restored service. However, we 
then looked at nearby APs and could see them climbing as well. It doesn’t 
appear to be all our APs but some unknown subsection of them.
We only went to 8.10 as we had bought some 9105 APs.

That one’s interesting because it shows affected code is 8.5(140.0), and only 
one case... is TAC agreeing it’s the same bug? Just curious.

We are currently running 8.10.151 and have been for quite a few months with no 
issues as of yet.  Only two issues as of right now are a certain devices not 
being able to connect, working with TAC on those.  8.10.130 and 8.10.142 are 
covered in bugs.

Subject: [EXTERNAL] [WIRELESS-LAN] Cisco 8540 Code Recommendation, Based on 
Stability?
Hi all,

After a tumultuous series of code versions, awhile back we settled on 8.5.151.0 
and hung on to it like grim death because it was very, very reliable.

Given that 8.5 code goes end-of-support at end of 2021, combined with latest 
rounds of announced vulnerabilities, I’m looking for recommendations in the 
8.10 train based on wanting stability above all. We have 3800s and 3700s 
currently, likely to stay that way through the next academic year.

Has anyone found an 8.10. code version for the 8540 that supports the 3700 and 
3800 while providing good daily stability?

Thanks,

That one’s interesting because it shows affected code is 8.5(140.0), and only 
one case... is TAC agreeing it’s the same bug? Just curious.

We are on 8.10.151 for the last couple of months here at Loughborough 
University in England. We think we are being hit quite badly by this bug:
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvp31778
with around 6% of our 2802i APs being currently affected.
It’s a really annoying bug too as to the user they appear to be connected to 
Wi-Fi but they have no network activity at all. Also the APs seem fine from a 
monitoring perspective unless you are either carefully monitoring their memory 
usage, or they get so far out of memory that they appear to lose their 
registration with the controller.
As such, I really can’t recommend 8.10.151.

Subject: [EXTERNAL] [WIRELESS-LAN] Cisco 8540 Code Recommendation, Based on 
Stability?
Hi all,

After a tumultuous series of code versions, awhile back we settled on 8.5.151.0 
and hung on to it like grim death because it was very, very reliable.

Given that 8.5 code goes end-of-support at end of 2021, combined with latest 
rounds of announced vulnerabilities, I’m looking for recommendations in the 
8.10 train based on wanting stability above all. We have 3800s and 3700s 
currently, likely to stay that way through the next academic year.

Has anyone found an 8.10. code version for the 8540 that supports the 3700 and 
3800 while providing good daily stability?

Thanks,

Re: [WIRELESS-LAN] [EXTERNAL] [WIRELESS-LAN] Cisco 8540 Code Recommendation, Based on Stability?

[Jonathan Oakden]

We are on 8.10.151 for the last couple of months here at Loughborough 
University in England. We think we are being hit quite badly by this bug:
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvp31778
with around 6% of our 2802i APs being currently affected.
It’s a really annoying bug too as to the user they appear to be connected to 
Wi-Fi but they have no network activity at all. Also the APs seem fine from a 
monitoring perspective unless you are either carefully monitoring their memory 
usage, or they get so far out of memory that they appear to lose their 
registration with the controller.
As such, I really can’t recommend 8.10.151.

We had multiple issues with the 8.10.130.0 code, including unexplained 8540 
controller reloads and random model 2700, 3700 and 2800 reboots, but since 
upgrading to 8.10.151.0 back in mid-March, we've been very stable. Knock on 
wood. The 8.10.151.0 is supporting our 1700, 2700, 2800, 1810, 1815, 2800 and 
9120 models just fine on our 8540 HA pairs.

Subject: [WIRELESS-LAN] Cisco 8540 Code Recommendation, Based on Stability?


Hi all,



After a tumultuous series of code versions, awhile back we settled on 8.5.151.0 
and hung on to it like grim death because it was very, very reliable.



Given that 8.5 code goes end-of-support at end of 2021, combined with latest 
rounds of announced vulnerabilities, I’m looking for recommendations in the 
8.10 train based on wanting stability above all. We have 3800s and 3700s 
currently, likely to stay that way through the next academic year.



Has anyone found an 8.10. code version for the 8540 that supports the 3700 and 
3800 while providing good daily stability?



Thanks,

CSCvu24770 Various Android 10 phones fail to associate.

This bug is still affecting 8.10.151.0 if you are using FT Adaptive. FT has to 
be disabled or some Android devices cannot associate to 802.1X SSID. I have 
seen Oppo, OnePlus, Xiaomi, LG and Moto phones are affected by this issue.

We had multiple issues with the 8.10.130.0 code, including unexplained 8540 
controller reloads and random model 2700, 3700 and 2800 reboots, but since 
upgrading to 8.10.151.0 back in mid-March, we've been very stable. Knock on 
wood. The 8.10.151.0 is supporting our 1700, 2700, 2800, 1810, 1815, 2800 and 
9120 models just fine on our 8540 HA pairs.

Subject: [WIRELESS-LAN] Cisco 8540 Code Recommendation, Based on Stability?


Hi all,



After a tumultuous series of code versions, awhile back we settled on 8.5.151.0 
and hung on to it like grim death because it was very, very reliable.



Given that 8.5 code goes end-of-support at end of 2021, combined with latest 
rounds of announced vulnerabilities, I’m looking for recommendations in the 
8.10 train based on wanting stability above all. We have 3800s and 3700s 
currently, likely to stay that way through the next academic year.



Has anyone found an 8.10. code version for the 8540 that supports the 3700 and 
3800 while providing good daily stability?



Thanks,
