4.6 The Rapid Spanning Tree
Protocol
PSSnet SHL - Redundancy Configuration
Pilz GmbH & Co. KG, Felix- Wankel Str. 2, 73760 Ostfildern
X Filter table
With STP, the age of the entries in the filter table determines the updating.
RSTP immediately deletes the entries in those ports affected by a
reconfiguration.
X Reaction to events
Without having to adhere to any time specifications, RSTP immediately
reacts to events such as connection interruptions, connection
reinstatements, etc.
Note: The price to be paid for this fast reconfiguration is the risk that data
packets may be duplicated or mixed up during the reconfiguration phase. If
this is unacceptable for your application, switch to the slower Spanning Tree
Protocol or select one of the other, faster redundancy procedures described
in this manual.
4.6.5 Configuring the Rapid Spanning Tree
Set up the network to meet your requirements.
Note: Before you connect the redundant lines, you must complete the
configuration of the RSTP.
You thus avoid loops during the configuration phase.
Select the Redundancy:Rapid Spanning Tree:Global dialog.
