WebAutomatic edge port. MS switches will automatically place all access interfaces into EDGE mode. This will cause the interface to immediately transition the port into STP forwarding mode upon linkup. The port still participates in STP. So if the port is to be a part of the loop, the port eventually transitions into STP blocking mode. WebJul 3, 2024 · Figure 1 shows how STP reacts to a topology change. Figure 1-2 TCN transmission and TC flooding. When the status of the port at point T changes, a …
