CLI – This example shows the STA attributes for port 5.
Configuring Interface Settings
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 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.)
Command Attributes
The following attributes are read-only and cannot be changed:
• STA State – Displays current state of this port within the Spanning
Tree. (See Displaying Interface Settings on page 3-134 for additional
information.)
- Discarding - Port receives STA configuration messages, but does
not forward packets.
