WebNov 17, 2024 · The STP port priority impacts which port is an alternate port when multiple links are used between switches. In our test topology, shutting down the link between SW3 and SW5 forces SW5 to choose one of the links connected to SW4 as a root port. Example 3-5 verifies that this change makes SW5’s Gi1/0/4 the root port (RP) toward SW4.
