Cisco Catalyst 9800-40 Wireless Controller

lachimi-sanyasi — Thu, 10 Oct 2024 00:51:14 GMT

Hi Have upgraded Cisco Catalyst 9800-40 Wireless Controller from 17.6.6 to 17.09.05 and it was working fine for few hours. I notice it went back to its previous version when I login next time. Any reason why? please help

How did you do the upgrade? CLI or web interface? Did you save the configuration?

If the command "install commit" is not entered and the roll-back timer (I think 8 hours), the WLC will roll back to the previous version.

I did upgrade from GUI

I did cli upgrade

If the upgrade was done using GUI, did anyone click the "Commit" button?

Re: Cisco Catalyst 9800-40 Wireless Controller

lachimi-sanyasi — Thu, 10 Oct 2024 00:35:43 GMT

I don't think I saw the commit button. I did save and reload after everything was successful.

Sounds to me something unsave was left and that´s why the old code returned.

From the controller, post the complete output to the command "dir bootflash:*.conf".

most likely the cause

If you do not run the install commit command within 6 hours of the install activate issu command, the system will revert to the original commit position. You can choose to delay the commit using the Delayed Commit procedure.

How do I do that from GUI can you please tell me?

Re: Cisco Catalyst 9800-40 Wireless Controller

Also, which version of IOS is the latest and stable one for the Cisco Catalyst 9800-40 Wireless Controller? Any suggestion?

Re: Cisco Catalyst 9800-40 Wireless Controller

lachimi-sanyasi — Thu, 10 Oct 2024 05:08:18 GMT

so 17.12.3 is better than 17.09.05?

Does it have any bugs? please help me to choose the best one. I can't afford to have more downtime.

cheers

Mark Elsen — Thu, 10 Oct 2024 05:15:44 GMT

- You should go to 17.12.3 , probably even 17.12.4 ,
17.9.x is considered End Of Life ; in these complex ages there will always be bugs , but it must be seen
from a context that the improvements should always be more important then (remaining) bugs ,

Re: Cisco Catalyst 9800-40 Wireless Controller

Leo Laohoo — Thu, 10 Oct 2024 05:39:51 GMT

We have dumped 17.9.X because it is FUBAR.

We are currently on 17.12.3 and have started testing/migrating to 17.12.4.

1. Every version of code has bugs - just about selecting the one which has the least number of bugs affecting the features you use and testing it.
2. Always refer to the TAC recommended code - link below. TAC are still recommending 17.12.3 but there are a number of crucial fixes in 17.12.4.
3. I would normally say use the TAC recommended option but like Leo and others we have dumped 17.9 and moved to 17.12.4. Note that there are SMUs and APSP (which address a number of WLC and AP bugs in 17.12.4) available which should be installed together with 17.12.4.
4. And always remember to COMMIT after you upgrade!
