Web17 Nov 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. WebThe STP Algorithm. The Spanning-Tree algorithm performs a couple of steps to make sure that the topology is loop-free and Ethernet is going to work correctly: Electing a Root Bridge - The very first thing that STP does is to elect a Root Bridge. This is the most important switch in the topology. It will be the root of the loop-free tree.
