has been accepted as the root device of the Spanning Tree network.
• Root Path Cost – The path cost from the root port on this switch to the root device.
• Configuration Changes – The number of times the Spanning Tree has been reconfigured.
• Last Topology Change – Time since the Spanning Tree was last reconfigured.

Configuring Interface Settings for STA
Use the Spanning Tree > STA (Configure Interface - Configure) page to configure RSTP and MSTP
attributes for specific interfaces, including port priority, path cost, link type, and edge port. You may
use a different priority or path cost for ports of the same media type to indicate the preferred path,
link type to indicate a point-to-point connection or shared-media connection, and edge port to
indicate if the attached device can support fast forwarding. (References to “ports” in this section
means “interfaces,” which includes both ports and trunks.)
