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.)
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 11-10 for additional information.)
• Discarding - Port receives STA configuration messages, but does not forward
packets.
• Learning - Port has transmitted configuration messages for an interval set by
the Forward Delay parameter without receiving contradictory information. Port
address table is cleared, and the port begins learning addresses.
• Forwarding - Port forwards packets, and continues learning addresses.
• Trunk 19 – Indicates if a port is a member of a trunk.
