Figure 22. Edge PortA port can be both a point-to-point and an edge port at the same time. It operates in full-duplex and has no STP or RSTP devices connected to it. Figure 23 illustrates a port functioning as both a point-to-point and edge port.Figure 23. Point-to-Point and Edge PortDetermining whether a bridge port is point-to-point, edge, or both, can be a bit confusing. For that reason, do not change the default values for this RSTP feature unless you have a good grasp of the concept. In most cases, the default values work well.Edge Port
