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.)
