If a bridge port is operating in full-duplex mode, than the port is functioning
as a point-to-point port. Figure 31 illustrates two AT-FS750/24POE Fast
Ethernet Smart Switches that have been connected with one data link.
With the link operating in full-duplex, the ports are point-to-point ports.
Figure 31. Point-to-Point Ports
If a port is not connected to any further bridges participating in STP or
RSTP, then the port is an edge port. Figure 32 illustrates an edge port on
an AT-FS750/24POE Fast Ethernet Smart Switch. The port is connected
to an Ethernet hub, which in turn is connected to a series of Ethernet
workstations. This is an edge port because it is connected to a device
operating at half-duplex mode and there are no participating STP or RSTP
devices connected to it.
