can simple patch cord cause network loop?
in my network someone connect simple patch cord cable in two port of d-link swithes,and another people said that this one cause loop!
but i said them that if we connect "cross-over cable" in two port of the same swith we have loop and with patch cord we dont have any loop in entire of the network
accourding the this article:
A network loop appears when two ports belonging to the same VLAN have a link to each other, or when there are two or more paths between two switches. Malicious users can physically create network loops, and the easiest way to do that is connecting a cross-connect cable to two ports that belong to the same switch and the same VLAN (the same broadcast domain).
i want to ask you that is my idea is true or not?
