  • A Root Port is a single port that has the cheapest path to the Root Bridge. From the switch to the Root Bridge, the Root Port on the Bridge (Switch) has the lowest Spanning Tree Path Cost.
  • The root port provides a direct connection to the single root bridge, or the quickest way to the root bridge.
  • If more than one connection links to the root bridge, the bandwidth of each link is used to compute the port cost.
