Figure 17. Point-to-Point Ports
A port operates as an edge port when it is connected to a network terminal
device such as a workstation or a server. An edge port on a bridge should
not have any STP or RSTP devices connected to it either directly or
through another device connected to that port. In this configuration since
the port has no STP or RSTP devices connected to it, it will always forward
network traffic. Figure 18 illustrates a port functioning as an edge port.

Mixed STP and
RSTP Networks
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.
If you decide to activate spanning tree on the switch, Allied Telesis
recommends RSTP instead of STP even when all of other switches in the
network are running STP. The AT-GS950/48PS switch can combine RSTP
with the STP of the other switches. The switches monitors the traffic on
each port for BPDU packets. Ports that receive RSTP BPDU packets
operate in RSTP mode while ports receiving STP BPDU packets operate
