RE: [WIRELESS-LAN] Cisco WLC code recommendations

It was indeed a space issue.  I cleared out a couple directories, which put the 
free space on flash: at around 17MB and retried the “download backup”, which 
was successful.

I know for this AP I had to do a bios level recovery, which entailed loading a 
different firmware than what was on the AP.  I’m sure this contributed the lack 
of space, but regardless, if for whatever reason space is tight on the AP you 
definitely want to manually clean house.

Googling a bit has yielded the possible explanation that there may not be 
enough space in flash.

I’m trying to see if I can free up any.

leery of yet another protracted TAC case.

RE: [WIRELESS-LAN] Cisco WLC code recommendations

[Jason Cook]

Strange. Appeared to work well for us… seems over half our AP’s were not 
holding the right secondary. I didn’t count, yesterday but a lot of them were 
3.0.51 as well,.

I’d have to dig up our first TAC case to confirm but for us I reckon this 
started with 8.0 from 7.6 where upon upgrade we had about 20 out of 300 3602i’s 
failed  after upgrade. All fixed in the end with persistent reboots ☺

This thread has me curious- I do see the occasional loss of AP name and config- 
like the AP goes back to default. Looking at our thousands of APs, I see some 
of the 7.1x backup code, but lots more of 3.0.51.0. I Tried to manually pull 
down newer backup image, and the process fails so I’m guessing  there’s 
something amiss on the file system on these APs (have yet to look, anticipating 
not enough room in flash or similar).

phone with one of our techs who physically rebooted an AP and I’m now waiting 
to see if it will come back.  When the AP is in the “bad state”, it shows up as 
a CDP neighbor on the switch as AP.., I can ping it, but ssh and 
telnet sessions are refused.

I just looked and noticed a bunch of my APs show Backup SW version as 7.3.x, 
where most of them correctly show a Primary of 8.2.151.0 and a Backup of 
8.2.131.40.

I’m going to try the “Download Backup” to one of these APs to see if it fixes 
that.

Ken,

For the AP’s that have lost their name and require a reboot. Would you check 
the following for me?

On WLC or PI, what do the problematic WAPs report as their backup software 
version? Typically, it should be the same as the “backup image” under 
commands->config boot on the controller. If it’s instead an older version e.g. 
7.1.x, let me know.

It’s circumstantial at this point, but I’ve noticed a pattern.

  *   AP’s that exhibit the problem tend to also fail AP Image Pre-download 
(Download Primary) during code upgrades. If you make a note of these failures, 
those WAPs are more likely to have mental issues.
  *   AP’s that exhibit the problem have very old (what shipped on it) code in 
the backup location e.g. 7.x
  *   Issuing a AP Image Pre-download, Download Backup to these AP’s will 
replace the old code in the backup location.
  *   Once the old backup image is updated, AP pre-download (Primary) now works 
during code upgrades, and the AP’s seem to stop losing their minds.

We are currently running a handful of 5508s with 8.0.133.0 and have been
stable for some time with around 400 APs and upwards of 1.5k clients. We
also run a half dozen 5520s with 8.2.141.0 and they have been running solid
with around 1k APs each and upwards of 10k clients. We do not however run
anything but 2600, 3600, 2700 and 3700 APs.



The only issue I have seen that I don’t understand well yet is related to
some APs losing the minds during network interruptions. The APs will appear
up from CDP neighbor information, but will have lost their name and will
not connect to their configured primary or secondary controllers. A power
cycle will often recover the AP, but not always. I believe that issue
started with 8.2.



Thank you.

For the AP’s that have lost their name and require a reboot. Would you check 
the following for me?

On WLC or PI, what do the problematic WAPs report as their backup software 
version? Typically, it should be the same as the “backup image” under 
commands->config boot on the controller. If it’s instead an older version e.g. 
7.1.x, let me know.

It’s circumstantial at this point, but I’ve noticed a pattern.

  *   AP’s that exhibit the problem tend to also fail AP Image Pre-download 
(Download Primary) during code upgrades. If you make a note of these failures, 
those WAPs are more likely to have mental issues.
  *   AP’s that exhibit the problem have very old (what shipped on it) code in 
the backup location e.g. 7.x
  *   Issuing a AP Image Pre-download, Download Backup to these AP’s will 
replace the old code in the backup location.
  *   Once the old backup image is updated, AP pre-download (Primary) now works 
during code upgrades, and the AP’s seem to stop losing their minds.

We are currently running a handful of 5508s with 8.0.133.0 and have been stable 
for some time with around 400 APs and upwards of 1.5k clients. We also run a 
half dozen 5520s with 8.2.141.0 and they have been running solid with around 1k 
APs each and upwards of 10k clients. We do not however run anything but 2600, 
3600, 2700 and 3700 APs.

The only issue I have seen that I don’t understand well yet is related to some 
APs losing the minds during network interruptions. The APs will appear up from 
CDP neighbor information, but will have lost their name and will not connect to 
their configured primary or secondary controllers. A power cycle will often 
recover the AP, but not always. I believe that issue started with 8.2.

Thank you.

If you have the new AP’s 1810/1850/2800/3800 then you should
absolutely upgrade as it offers huge improvements across the board
for those WAPs, including some fixes for client-side bugs.

to try to rush an upgrade during this week while Spring Break has
campus slower than normal. We’ve been refreshingly stable on MR4,
and not experiencing any of the resolved caveats so I’m leaning
towards waiting until end of semester. Does anyone know of
anything that rises to the level of a stand-out bug that is so
common and heinous that it drives this to “should update
immediately” status?

There was a bug introduced in one of the later beta builds which resulted in

I’ve been waiting on an engineering fix to help with the Kernel Panic on the 
1810’s, however I received an e-mail from Cisco last week that they found bugs 
in MR5 and it wasn’t recommended that we use it.  We’re running dual 8540’s/HA

I have Rlan’s, Flexconnect and building groups configured, so it may just be 
due to what we’re doing with our AP’s, but the only version of code that we can 
keep the Rlan’s up (reliably) is with 8.2.130.0.

Upgraded to 8.2.141.0 and everything went down when using Flexconnect/Rlan 
combination.

I’m waiting to hear from Cisco about when the code after MR5 is to be released 
and test it.

I’ve been waiting on an engineering fix to help with the Kernel Panic on
the 1810’s, however I received an e-mail from Cisco last week that they
found bugs in MR5 and it wasn’t recommended that we use it.  We’re running
dual 8540’s/HA



I have Rlan’s, Flexconnect and building groups configured, so it may just
be due to what we’re doing with our AP’s, but the only version of code that
we can keep the Rlan’s up (reliably) is with 8.2.130.0.



Upgraded to 8.2.141.0 and everything went down when using Flexconnect/Rlan
combination.



I’m waiting to hear from Cisco about when the code after MR5 is to be
released and test it.

If you have the new AP’s 1810/1850/2800/3800 then you should absolutely
upgrade as it offers huge improvements across the board for those WAPs,
including some fixes for client-side bugs.

Re: [WIRELESS-LAN] Cisco WLC code recommendations

[Jeffrey D. Sessler]

Ken,

For the AP’s that have lost their name and require a reboot. Would you check 
the following for me?

On WLC or PI, what do the problematic WAPs report as their backup software 
version? Typically, it should be the same as the “backup image” under 
commands->config boot on the controller. If it’s instead an older version e.g. 
7.1.x, let me know.

It’s circumstantial at this point, but I’ve noticed a pattern.

· AP’s that exhibit the problem tend to also fail AP Image Pre-download 
(Download Primary) during code upgrades. If you make a note of these failures, 
those WAPs are more likely to have mental issues.

· AP’s that exhibit the problem have very old (what shipped on it) code 
in the backup location e.g. 7.x

· Issuing a AP Image Pre-download, Download Backup to these AP’s will 
replace the old code in the backup location.

· Once the old backup image is updated, AP pre-download (Primary) now 
works during code upgrades, and the AP’s seem to stop losing their minds.

We are currently running a handful of 5508s with 8.0.133.0 and have been stable 
for some time with around 400 APs and upwards of 1.5k clients. We also run a 
half dozen 5520s with 8.2.141.0 and they have been running solid with around 1k 
APs each and upwards of 10k clients. We do not however run anything but 2600, 
3600, 2700 and 3700 APs.

The only issue I have seen that I don’t understand well yet is related to some 
APs losing the minds during network interruptions. The APs will appear up from 
CDP neighbor information, but will have lost their name and will not connect to 
their configured primary or secondary controllers. A power cycle will often 
recover the AP, but not always. I believe that issue started with 8.2.

Thank you.

Ken

Shayne,

Did they say, “bugs in MR5” or, bugs in the then current engineering release? 
Big difference, and while there was one of the engineering releases that 
introduced a radio reset feature, that bug was fixed in later engineering 
releases.

with unpredictable frequency. We had to upgrade. It wasn't a question for us.

If you have the new AP’s 1810/1850/2800/3800 then you should absolutely upgrade 
as it offers huge improvements across the board for those WAPs, including some 
fixes for client-side bugs.

Re: [WIRELESS-LAN] Cisco WLC code recommendations

[Jeffrey D. Sessler]

One note on MR 5. If you use Prime, there was a code change in MR5 to the AP 
Neighbor MAC address format to help identify if a 5G radio is on slot 0 or slot 
1 (XOR support). As such, until the patch hits for PI 3.1.5, WAP neighbor 
display in prime will be partially broken (won’t show AP name and will think 
it’s not in PI).

This is the change:
When the last 4 bits of neighbor MAC   is
-  0x0 : slot 0’s MAC address
-  0xF  : slot 1’s MAC address

Short answer is it is a bug.  A “Kernel Panic”.  AP loses its mind.Very 
prevalent on the new stuff, to a much lesser degree affects “older” stuff.

Sometimes the reset fixes it.  Sometimes not.  We doubled down on 1810’s and 
2802’s.  Bugs galore.  Which are actively being fixed-to be fair.

We are running on engineering code and HUGE improvements have been made. Soon, 
I think/hope, it will be rock solid.

We are currently running a handful of 5508s with 8.0.133.0 and have been stable 
for some time with around 400 APs and upwards of 1.5k clients. We also run a 
half dozen 5520s with 8.2.141.0 and they have been running solid with around 1k 
APs each and upwards of 10k clients. We do not however run anything but 2600, 
3600, 2700 and 3700 APs.

The only issue I have seen that I don’t understand well yet is related to some 
APs losing the minds during network interruptions. The APs will appear up from 
CDP neighbor information, but will have lost their name and will not connect to 
their configured primary or secondary controllers. A power cycle will often 
recover the AP, but not always. I believe that issue started with 8.2.

Thank you.

I’ve been running various beta versions of MR5 in production and have had no 
problems.

If you have the new AP’s 1810/1850/2800/3800 then you should absolutely upgrade 
as it offers huge improvements across the board for those WAPs, including some 
fixes for client-side bugs.

I just went through the release notes, am struggling with whether to try to

normal. We’ve been refreshingly stable on MR4, and not experiencing any of the

anyone know of anything that rises to the level of a stand-out bug that is so 
common and heinous that it drives this to “should update immediately” status?

Short answer is it is a bug.  A “Kernel Panic”.  AP loses its mind.Very 
prevalent on the new stuff, to a much lesser degree affects “older” stuff.

Sometimes the reset fixes it.  Sometimes not.  We doubled down on 1810’s and 
2802’s.  Bugs galore.  Which are actively being fixed-to be fair.

We are running on engineering code and HUGE improvements have been made. Soon, 
I think/hope, it will be rock solid.

We are currently running a handful of 5508s with 8.0.133.0 and have been
stable for some time with around 400 APs and upwards of 1.5k clients. We
also run a half dozen 5520s with 8.2.141.0 and they have been running solid
with around 1k APs each and upwards of 10k clients. We do not however run
anything but 2600, 3600, 2700 and 3700 APs.  

 

The only issue I have seen that I don't understand well yet is related to
some APs losing the minds during network interruptions. The APs will appear
up from CDP neighbor information, but will have lost their name and will not
connect to their configured primary or secondary controllers. A power cycle
will often recover the AP, but not always. I believe that issue started with

RE: [WIRELESS-LAN] Cisco WLC code recommendations

[Jeffrey D. Sessler]

On the issue with the 2800/3800’s are RF leader. There is a Cisco document 
covering the proper setup of RF leaders with the XOR-specific WAP’s.
http://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-3/b_RRM_White_Paper.html

Basically, they must have a RF leader that is running the code level that 
supports them i.e. if 8.0 is the RF leader you will have issues with many 
things including the XOR radio’s ability to auto-change roles. Also, the RF 
leader must be the same for 2.4 and 5, making manual assignment of the RF 
leader necessary.

We only have a handful of 3702i APs deployed but do not recall anything

doubt this is related with the random disassociations but we took Lee Badman’s 
suggestion to turn down the client exclusion timer from 60 seconds to 5 seconds 
on our dot1x SSIDs.  It seems to have helped incorrectly configured and/or 
poorly behaving clients a lot yet still provides some level of security.

I would guess everyone else knows this but running 8.0, 8.2, and/or 8.3 across 
the same RF grouping may give you unpredictable results.  Specifically 
2800/3800 APs that I tried to let do auto channel width in a small area….. for 
that area it worked fine until an 8.0 WLC was the RF leader.  At that point all 
of the APs on the newer controller code that supported auto channel width went 
to 80MHz channels.  It was a quick fix but it made me think someone was messing 
with me for a while……

We’re on 8.0.121.0 and we’re experiencing delayed association/roaming,

randomly disassociate for a minute or two at a time even during use when

Official MR5 is getting closer but still a few days out (maybe a week). If you

I’ve been running the beta code across five 5508’s and it’s been solid.

Oh my.

Run, run far far away. :)

1810's are the buggiest.  And require MR5 (Which is not out officially yet)

But some bugs that hit the 2802's hard are resolved in MR5.  (users not 
connecting on Intel Chipsets) are resolved in MR5.
8.2.141 is the minimum I would suggest.  But MR5 will be out in the next 10 
days.-I have been told)


8.2.110.0 is the minimum code, however  Go to the newest code.  These AP's 
are *new* (and require the latest code).  They rebuilt the code from scratch 
for 2802/1810's.

We are currently running version 8.0.133.0 on our Cisco 5508 controllers, as 
our current access points are primarily 3500s and 3600s. However we have 
recently purchased a batch of 2802i access points whose minimum supported 
version is 8.2.110.0.  I was looking to the group for their recommendations on 
a stable version of code which will support our new 2802i access points.

Bruce,

 

I've got 2 clusters (WiSM2-HA), with a mix of APs from 1142,
3502, 3702, 3802, and 702 model numbers.  We're running 8.2.141.0 on both
clusters, with over 900 APs on each, and around 4500 clients on each as
well.  We upgraded to 8.2.141.0 72 days ago, and have had no outages (due to
the controllers/code) since.

We had been running 8.0.121.0 for almost a year, without issues.  We
upgraded to 8.0.133.0 3 weeks ago, and have not seen any issues so far.
(glad to be on this side for a change, TJ!)

Running HA-SSO (8.0.X)and have been experiencing issues since October.
Multiple engineering releases have been provided by Cisco, the latest caused
HA pairs to crash. That release was promptly downgraded. 

 

HA-SSO is a great feature, but I have heard of multiple institutions running
into problems since its inception. If you aren't experiencing problems with
it, be weary of your next upgrade. We weren't having issues with 7.6 but
began seeing them with 8.0. (opposite of Rice I believe)

 

I'm looking forward to the next suggested release, we try to stay off newer
releases unless required for necessary support or features.

We've been running HA-SSO on our WiSM-2's since we put them in in 2013.
We've had some issues, all software bug related, over that time, in the
first few versions; however, the last few versions (since May of last year)
have been stable for us.  I'm happy to talk off-list if you have any
questions.

Hopefully not too far off topic, but has anyone experienced issues with

the beginning we ran it without any issues, but swapped over to the N+1 per

We've been on the 8.0.XX for quite a while on our 5508's and it's been

About to trial 8.2 though on 8510's so that's going to be interesting I'm

Re: [WIRELESS-LAN] Cisco WLC code recommendations

[Jeffrey D. Sessler]

If you think you’re going to add the new Wave2 AP’s to your mix e.g. 
1850/2800/3800, then you’ll need to go to the just released (yesterday) 8.2MR1.

7.6 is a deferred release, so 8.0.x or 8.2.x are your choices. In 8.0, 
8.0.135.0 was just released. It’s the same as the 8.0.132/133 but has the 
support for the new –B regulatory domains that are effective June 2nd. Since 
you can’t get –A parts in the US now, you’ll need to be at that release if you 
add new –B APs.

8.2MR1 also supports the –B reg domains.

You should consider the 8.1 train dead (or rapidly dying). It was always
meant to be a short lived train. You would want to focus on the latest 8.0
build if you're primary focus is a long lived and if you are unable to
stomach the rapid code churn of the bleeding edge - and of course have no
new hardware or software feature requirements.

One of those projects is the upgrade of our 5508 controllers which are

discussion regarding recommended versions of Cisco WLC code and some of the 
recommendation included; 8.0.121.0 and 8.1.131.X, I was looking to see if time
