WLC 5508 IOS error

Translator · ‎09-23-2022

Thank you for clicking first.
The WLC 5508 does not match the product when downloading and upgrading image files from an FTP server after IOS formatting.
Does anyone know about this problem?

For your information, the version is 8.5.182.

- What do you mean ? Use compatible software only : https://software.cisco.com/download/home/282600534/type/280926587/release/8.5.171.0 , which is the last release that the 5508 can run , what error do you get ?

Actually I would recommend 8.5.182.0 or 8.5.182.2 (from TAC only) if mobility is required.
https://software.cisco.com/download/home/282600534/type/280926587/release/8.5.182.0
As per https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/200046-tac-recommended-aireos.html#anc10
As long as you download the correct image and meet all the prerequisites as specified in the release notes then it will work.

FYI: 5508 uses AireOS not IOS and you should not need to format anything - simply download the image from Cisco then upload to the WLC.
