Time of day restriction question.

I work for a boarding school, we have severe issues with proxies, like 90% of our students use them and we can't really stop them. What I would like to do is shut down specific ports at specific times. For instance I want ports 8/1-8/27 and 1/26-1/48 to shut down from 9pm-8am and again from 11am-5pm. How do I do this? (Also I'm new to this, so if you could Explain it like I'm five..it would help immensely.)

A little more information. We're running 3750 catalyst switches, we do have a web filter that filters them and "turns off" the internet, however proxies such as Hotspot shield and anchorfree get through it easily.

I inherited this system with little to no working knowledge of Cisco switches/command lines. Everything I know I've learned from advice on message boards and help threads on here, so any help would be appreciated.

Thank you so much in advance!

Hi,

If you've got the 12.2(55)SE or higher then you could use EEM to shut down the ports at specified times.
