Section 8
Rapid spanning tree protocol (RSTP)
8.1
Introduction
GUID-A065494F-F472-4177-A93F-D5FDF49B414F v1
Rapid Spanning Tree Protocol (RSTP) is a network protocol built for loop free network topology and
redundancy/backup connections between switches.
•
Support for RSTP will be available on the Station level network communication.
•
RSTP will only be available on the Access Point (AP) AP1 or AP3. AP1 uses port 1 and port 2;
AP3 uses port 3 and port 4.
•
RSTP will not be available on Optical Ethernet Module (OEM02) hardware (that is, on interface
AP5).
•
RSTP can be configured using Ethernet configuration tool (ECT) and PST in PCM600.

Configuring RSTP in the IED
GUID-D6BC55E2-9652-4A53-BCEA-B7352DFC8BCC v1
Access points can be configured to use the RSTP using ECT in PCM600. Either AP1 or AP3 can be
configured with RSTP and not both at the same time. ECT will not allow the RSTP on another AP if
RSTP is already configured on any of the APs. Settings related to the RSTP are available under PST
in PCM600 or on LHMI (under
Configuration menu/Communication/Ethernet Configuration/
RSTP
).
