Subject: Re: [WIRELESS-LAN] Cisco 8540 WLC random reboots

We had this issue very recently when upgrading our 8540s from 8.2.166.0 to 
8.5.131.0 (MR3):

A few days after the upgrade, the Standby 8540s started going through reboot 
loop, because it had an NaServCaCert_p12.pem certificate missing from the 
Active 8540. When the Standby can’t find the certificate on the Active 8540, it 
starts rebooting, until the Standby mercifully goes into Maintenance mode. 
During one of the reboots the certificate is restored on the Standby (I am 
told), but the Active 8540 still needs the NaServCaCert_p12.pem  certificate 
manually uploaded, in order for the HA SSO pair to be restored.

If one took the path of 8.2.x … upgrade to 8.3 (NaServCaCert_p12.pem created 
here?) … THEN upgraded to 8.5.X, you do not encounter the missing 
NaServCaCert_p12.pem certificate and rebooting standby WLC.

We are currently in the process of migrating to 8540s (8.5.120) from 8510s.  
Here recently we started noticing the HA unit on two of the pairs was in 
maintenance mode.  We rebooted the controllers and they seem to have stayed in 
a continuous boot loop.  We restarted one of the controllers to its emergency 
code (8.2.166) and it rebooted correctly without any issues, disabled SSO mode, 
rebooted back into 8.5.120 with no issues.  We enabled SSO again and 
immediately went back to having boot loop issues.  Is anybody else seeing this

Yes, we ran into this, as did other schools from what I hear.
After working with TAC for quite awhile, they came out with 8.5.131.0 
and that seems to fix the issue, as well as some other issues.


You probably hit bug CSCvi38017 (as did we). Fixed in 8.5MR3. 8.5.131.0 
has since been released, due to the ETSI-thingie.

FWIW, we run all of our 1815w APs on code version 8.5.120.0  in FlexConnect 
mode (although they worked when we tested them in Local mode as well).  I 
thought you might like to know that you potentially don't need to run them on 
8.4 code any longer.

Re: [WIRELESS-LAN] Cisco 8540 WLC random reboots

Jason,

FWIW, we run all of our 1815w APs on code version 8.5.120.0  in FlexConnect
mode (although they worked when we tested them in Local mode as well).  I
thought you might like to know that you potentially don't need to run them
on 8.4 code any longer.

Thanks!--JW

2018-07-09 Thread Price, Jamie G

Hi All,

Is there a general consensus that 8.5.131 is good code?

We are working to solve an issue in short- our IPV6 wireless will drop off 
wireless (we are in testing now). Our next hope is that a code upgrade will fix 
the issue. If this doesn’t work we will circle back with TAC and y’all will 
hear about this in future posts.

Thanks,
Jamie

Re: [WIRELESS-LAN] Cisco 8540 WLC random reboots

2018-07-09 Thread Matthew Craig

Yes, we ran into this, as did other schools from what I hear.

After working with TAC for quite awhile, they came out with 8.5.131.0 and that 
seems to fix the issue, as well as some other issues.

Its been bug wack-a-mole since 8.5 code came out, but so far (*fingers crossed* 
*knock-on-wood*) this one has dare I say been working alright.

immediately went back to having boot loop issues.  Is anybody else seeing this

Lots of bugs in 8.5.120, including some giant HA bugs.

The version of 8.5.131 coming later this month is where you'll want to be. 
Specifically, one of the fixes in the version of 8.5 coming later this month 
deals with HA issues.
