CLI – This example shows the STA attributes for port 5.
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.)
