Point-to-Point Ports and Edge Ports
Note
This section applies only to RSTP.
Part of the task of configuring RSTP is defining the port types on the
bridge. This relates to the device(s) connected to the port. With port type
defined, RSTP can reconfigure a network much quicker than STP when a
change in network topology is detected.
There are two possible selections: Point-to-Point and Edge Port.
If a bridge port is operating in full-duplex mode, than the port is
functioning as point-to-point. Figure 31 illustrates two AT-8324 Switches
that have been interconnected with one data link. With the link
operating in full-duplex, the ports are said to be point-to-point ports.
