That is not nice at all :(

Did you figure out a way to prevent it from switch side?

Yes it will create a loop. Not a fun time trying to track these things down. I've had some non-Cisco IP phones completely down a LAN.

Dear all;

I want to know what will happen if a user connect "by mistake" both the PC port and Switch port to the network switch? Will this create a loop? Anyone tried it before?
