network segment. All other ports are blocked, which means that they are prevented from forwarding
traffic.
The device supports the following STP versions:
Classic STP: Provides a single path between end stations, avoiding and eliminating loops.
Rapid STP: Detects and uses network topologies that provide faster convergence of the spanning
tree, without creating forwarding loops. While Classic STP prevents Layer 2 forwarding loops in a
general network topology, convergence can take between 30-60 seconds.
