●
You must manually set the classification of uplink and backbone ports to "valuable" using
the
set port classification
CLI command.
●
STP and Self Loop Discovery (SLD) are incompatible. However, If Spanning Tree is set to
rapid-spanning-tree 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
.
Spanning Tree Protocol CLI Commands
The following table contains a list of CLI commands for the Spanning Tree feature. The rules of
syntax and output examples are all set out in detail in the
Reference Guide for the Avaya C360
Converged Stackable Switch, 10-300506.
In order to... Use the following
command...
Enable/Disable the spanning tree
application for the switch set spantree
Set the bridge priority for
spanning tree set spantree priority
Set the RSTP bridge spanning
tree max-age parameter set spantree max-age
Set the RSTP bridge hello-time
parameter set spantree hello-time
Set the RSTP bridge
forward-delay time parameter set spantree forward-delay
Select between STP operation or
RSTP switch operation set spantree version
Display the bridge and per-port
spanning tree information show spantree
Set the TX hold count for the STA set spantree priority
