What it will happen if 'accidentally' i will connect 2 ports with the same utp cable? I'm asking here since i don't find anyware such a stupid and silly question but i'm curios about it, the router will damage or some internal parts? :) Or the switching part it will go mad? Or i don't know i'm just asking since my network knowledges are not so good.

router: port1 - utp to port2 , where port1 and port2 belongs to the same router

Nothing in the router will be damaged.

Routers operate at a higher level of the network stack than switches do, so assuming that you're connecting 2 routed interfaces, you won't have a broadcast storm that is typical when two (non-STP) L2 interfaces are connected.

The worst that will happen is that (obviously) no traffic will be routed through those interfaces.

Thank you sir for your answer, as for switches what would happen, broadcast storming? – Mihai Mar 22 '14 at 13:24
Do some research and find out! We don't spoon feed information here. This site is for professionals, and part of being a professional is being able to do your own research. – EEAA Mar 22 '14 at 13:25
