Which command configures a switchport as an RSTP point-to-point port?

Configuring a switchport as an RSTP point-to-point port is achieved using the command that sets the link type directly. The command "spanning-tree link-type point-to-point" explicitly instructs the switch to treat the port as a point-to-point connection. This designation is crucial in RSTP because point-to-point links have reduced convergence times compared to shared links, which can involve more devices and potential collisions.

This command ensures that the switch optimizes the spanning tree protocol operation by allowing RSTP to recognize the direct connection between two switches, thereby confirming that a rapid transition to forwarding state can occur. This command helps improve network efficiency and performance by reducing the time needed to adapt to topology changes.

Choosing this command effectively enables the switch to utilize its capabilities to facilitate rapid spanning tree convergence, which is a fundamental aspect of RSTP’s design. By enabling the proper link type, it allows the network to maintain high throughput and quick recovery from failures.
