4.7.1.4 STA Port Configuration
Configuring Interface Settings
You can 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.)
