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.)
