[cisco-voip] IP Phone Ports

[Corson, Teressa]

I, too, have had users plug both phone ports into the network.  Amazing how quickly the network goes down.  :)  I don't recommend trying it.  However, you will see lots of "pretty" flashing lights on the switches in the network!

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?
