set spantree portcost
Use this command to assign a cost value to a Spanning Tree or port. This parameter is used to
determine the best path between Spanning Tree devices. Therefore, lower values should be assigned
to ports attached to faster media, and higher values assigned to ports with slower media.
set spantree portcost port-string cost [sid]
NOTE: Port cost takes precedence over port priority (set spantree portpri). The cost
to the root is updated by each bridge at the root port.
