Couple of reasons i can see why the GUI go slow,

 

1. high CPU

2. check uptime if it is more than 1+years suggest to restart and check.

 

what is the code running on the device now ?

Along with suggestions from BB - have you tested different browsers?

If enabled, disable automatic redirection from http to https. That can cause this issue.

Hello,

Thanks for your response. I have included a screen shot of the existing area in my config that I think you are referring to.

What changes would I need to make?

We are running 8.3.150.0

Thanks

 

HTTP-HTTPS Configuration

HTTP Access ---- disabled
HTTPS Access 2 ----- enabled
WebAuth SecureWeb 1 ----- enabled
HTTPS Redirection ---- disabled
Web Session Timeout ---- 30 minutes

It would be this setting: HTTPS Redirection ---- disabled, but you've already set it correct.

Re: Its very slow to access WLC5508 by GUI

After you disabled HTTPS redirect, did you save the config and reload the WLC?

 

As mentioned, there is a bug, CSCvf74866, that causes the GUI to be very unresponsive.

 

You can also try to enable HTTP access and test using that (http://wlc-ip-address instead of https://wlc-ip-address).

Can you share "show process cpu" output from the 5508 WLC.
