WLC 5520 IOS UPGRADE in HA Set up

shailiniobrien — Mon, 05 Jul 2021 17:45:14 GMT

The upgrade for the 5520 HA set up from 8.2 to 8.3 completed. However, the bootloader shows different versions.

Attempted the upgrade from 8.3 to 8.5 . It failed during the upload of IOS file to the WLC.

Is the bootloader has something to do with this or a bug issue for the current 8.3 version ?

- Do you have a screenshot or can you provide logs from the failing sequence ?

I want to see the exact error message and I also want to see the exact firmware version you're going to.

This has been solved.

When you issue the show certificate command . It shows no certificate.

I contacted TAC and they have make me reseated the SD card. Certificate then shows Then I had proceeded the upgrade.
