Spanning Tree Protocol Cli Commands - Avaya W310 User Manual

The W310 configured to RSTP is able to simultaneously work with other switches
implementing either RSTP or STP without specific user intervention.
• Spanning Tree configuration is performed on the switch level.
• RSTP is interoperable with W310 Port Redundancy and PBNAC applications. If either
RSTP or PBNAC put the port in blocking, its final state will be "blocking".
• STP and Self Loop Discovery (SLD) are incompatible. However, if Spanning Tree is set
to RSTP version, there is no need to use the Self-loop-discovery feature; the RSTP
algorithm avoids loops generated by the IBM token ring cabling.
• The 802.1w standard defines differently the default path cost for a port compared to STP
(802.1d). In order to avoid network topology change when migrating to RSTP, the STP
path cost is preserved when changing the spanning tree version to RSTP. You can use
the default RSTP port cost by using the CLI command set port spantree cost
auto.
