Upgrade WLC9800

[HenryNguyen89]

Hi all,

My customer have a WLC 9800-L with software version 16.12.2s

Now, they're having a problem with WLC. Their WLC will stop working suddenly.

At that time, i cannot ping or telnet to WLC. WLC must to reboot (un-plug and plug power cable) to working normal.

And, after reboot, the old log disappeared. So i don't know what happend to WLC. Even i configured syslog for WLC, it's no use.

So, i want to upgrade software for WLC. But i'm not sure which software version is working stable.

Please help me T-T

Either a CPU hog or a memory leak. 

Please post the complete output to the following commands: 

dir flash:
dir crashinfo:tracelogs | exclude bin.gz

How about the following: 

dir flash:tracelogs | exclude gz
dir flash:core

TAC recommended versions for WLC are here https://www.cisco.com/c/en/us/support/docs/wireless/catalyst-9800-series-wireless-controllers/214749-tac-recommended-ios-xe-builds-for-wirele.html 

That being said look at the compadibility matrix to ensure APs will work with it

 https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html 

Take not of the release notes as upgrading from 16.x code to 17.x code may require double upgrade and most likely rommon upgrade as well
