STP Port and Trunk Configuration

You can configure RSTP 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 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.)
