I think I found the solution: ip http timeout-policy idle 3600 life 86400 
I have a N2024 and a N2048 and while in the web interface, I am always getting kicked out after 10 minutes because of 'inactivity', yet I am "checking this and changing that config". I was watching the Login Sessions times, and once it hits 10 min, it kicks me out. Is there a way to turn off the inactivity timer, or at least change it? Couldn't find anything in the user manual or online.
