There are two possible selections:
Point-to-point port
Edge port
The default setting for the RSTP port point-to-point status is automatic.
With the automatic setting, the point-to-point status is True of the port is
operating in full-duplex mode. If the port is operating in half-duplex mode,
then the point-to-point status is False.
Figure 26 illustrates two AT-GS950/24 switches that have been connected
with one data link. With the link operating in full-duplex, the ports are point-
to-point ports.
Figure 26. Point-to-Point Ports
If a port is operating in half-duplex mode and is not connected to any
further bridges participating in STP or RSTP, then you need to manually
define the port as an edge port. The default setting for the edge port status
is False. You must manually configure this setting for each port. There is
no automatic mode for the edge port setting. Figure 27 illustrates an edge
port on an AT-GS950/24 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.
