3850 Catalyst GUI Timeout

Elnook — Sat, 03 Aug 2024 02:52:50 GMT

Hi,

I downgraded to 16.3.9 on a 3850 for a lab environment as I want to use for its AP capabilities, as soon as I log into the GUI it gives me "Your session has timed out, please log in again"

Any suggestions?

start with some basic checks, make sure http and https services are configured and web auth is set to local with priv 15 credentials.

switch# configure terminal
switch(config)# ip http server
switch(config)# ip http secure-server
!
switch# configure terminal
switch(config)# username your_username privilege 15 secret your_password
!
switch(config)# ip http authentication local

Once I log in I am presented with the message and I cant do anything other that click ok. I was able to login to the GUI with no issues before I downgraded to 16.3.9 from 16.12.09. Th only reason I did that was so I can work with AP in a lab environment.

- Check the logs on the 3850 when that happens ,

looks buggy, can you try to restart HTTP service and try incognito

The logs look normal reporting when I log in successfully no errors. I just upgraded to the latest software 16.12.11 the web interface is running fine and ordered a slightly used 4400 Series Wireless LAN Controller AIR-WLC4402-12-K9 for my lab learning. I appreciate all the help here thanks all!!!!!!!!

- Have a try by defining another admin user (name) for GUI access , with local authentication (no radius - e.g.)

Did you try incognito (private browsing) as @Ambuj M suggested?
This is most likely a browser/caching/cookies issue.
Also try clearing history and cache and cookies.
If that doesn't help it may be a browser incompatibility so you might need to run an older browser version to support the old software version - I'd generally suggest Firefox.
