Allied Telesis AT-9000/28 - Restoring the Default Parameter Settings

Chapter 37: Spanning Tree Protocol (STP)
492 Section VI: Spanning Tree Protocols
Restoring the Default Parameter Settings
If you want to restore the default values to all the STP switch and port
parameters on the switch, use the SPANNING-TREE STP PURGE
command in the Global Configuration mode. Here are the requirements to
this command:
 STP must be the active protocol on the switch.
 STP must be disabled on the switch.
This example disables STP on the switch and restores the default settings
to the spanning tree protocol:
awplus> enable
awplus# configure terminal
awplus(config)# no spanning-tree stp enable
awplus(config)# spanning-tree stp purge
