5508 WLC upgrade syntax

davinci — Mon, 05 Jul 2021 17:58:52 GMT

I'm having problems with the TFTP syntax when attempting to download code to WLC. What is wrong with this?

Here are screenshots of my TFTP server config and the WLC with error.

IP reach-ability exists between these devices. There is no firewall rule.

You mean, you can ping TFTP server from the controller and vice versa?

I would check TFTP server IP binding & security settings to make sure they configured appropriately.

I would also try code upgrade via CLI.

See what msg you got once you go with CLI approach. CLI approach is always recommended as it gives some output why is it failing.

transfer download mode tftp

transfer download datatype code

transfer download serverip <tftp_srv_ip>

transfer download path ./

transfer downlaod filename AIR-CT5500-K9-8-5-151-0.aes

transfer download start

Have had issues with solarwinds TFTP server with large files before.

Can you try SFTP? or HTTP to download the file

If you have a MACOS try Transfer (https://www.adriangranados.com/apps/transfer)

Only other things to try

Path ./

Or as Rasika says try the CLI

Windows Firewall correctly configured to allow UDP 69 or the application?

logs on Solarwinds dont show any activity. I believe that my syntax for path directory is not correct.

is that the correct path directory? file is located in C:\TFTP-Root

SW logs the.... attempt to connect. If the path was wrong it would log invalid file, or something like that.

if you instance is not logging anything then I suspect that the wlc has not established a link to your tftp server. On you desktop is it not?

Hello,

Have you tried another TFTP program like TFTPd64? it's free and works great and very ease to setup

I would also try using FTP to download the code to the WLC

I had to copy code from TFTP server to local router bootflash, then I copied code from router to WLC. I left file path field empty on the WLC and the copy to WLC was successful
