Link Types

RSTP distinguishes between three different 'link types':
Edge - a port that is connected to an end host. Moves directly to forwarding, without negotiation.
Point-to-point - a direct connection between two switches.
Shared - a connection to a hub. Must operate in half-duplex mode.
Edge ports are connected to end hosts.
Because there is no risk of creating a loop, they can move straight to the forwarding state without the negotiation process.
They function as a classic STP ports with PortFast enabled.
To enable it, it uses the same command as PortFast.
Point-to-point ports connect directly to another switch.
They function in full-duplex.
You don't need to configure the interface as point-to-point (it should be detected).
Shared ports connect to another switch (or switches) via a hub.
They function in half-duplex.
You don't need to configure the interface as shared (it should be detected).
