Edge Port

Figure 26. Edge Port

Aport 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 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.

RSTP IEEE 802.1w is fully compliant with STP IEEE 802.1d. Your network can consist of bridges running both protocols. STP and RSTP in the same network can operate together to create a single spanning tree domain.
