Port Roles
The root port of a switch connects this switch to the root switch - either directly or via
another switch (designated switch).
The designated port is the port at a designated switch that is connected to the root port
of the next switch.
No additional switches/bridges are connected to edge ports. Termination devices are
connected to edge ports.
An alternate port is a path to the root, which, however, did not become a root port. I.e.,
this port is not part of the active topology.
