Figure 26. Edge Port

A port can be both a point-to-point and an edge port at the same time. It
operates in full-duplex mode and has no STP or RSTP devices connected
to it. Figure 27 illustrates a port functioning as both a point-to-point and
edge port

.

Figure 27. Point-to-Point and Edge Port

Determining 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.
