Chapter 12: STP, RSTP, and MSTP
Section II: Local and Telnet Management 192
If a port is operating in half-duplex mode and is not connected to any
further bridges participating in STP or RSTP, then the port is an edge
port. Figure 64 illustrates an edge port on an AT-8411 TX line card in an
AT-8400 chassis. 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.
