Spanning Tree Protocol essentially stops packet loops (where the same packet transports around your switches constantly) which causes broadcast storms and thus grinds the network to a complete halt. | Spanning Tree Protocol essentially stops packet loops (where the same packet transports around your switches constantly) which causes broadcast storms and thus grinds the network to a complete halt. | ||

For what we do with our systems, there are generally two data switches between devices, with a link between them (per VLAN) which looks like this diagram below: | For what we do with our systems, there are generally two data switches between devices, with a link between them (per VLAN) which looks like this diagram below: | ||

+ | In this example, we can see just a single link from Switch A to Switch B. This means that there cannot be any Loops, so STP would not be required here (although it is worth remember that STP in some form runs on a Cisco be default). | ||
