This example shows general STA configuration and 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
Note: The following attributes are read-only and cannot be changed:
•Port: Ports only; i.e., no trunks or trunk port members.
• STA State: Displays current state of this port within the Spanning Tree:
• 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: Indicates if a port is a member of a trunk. (STA Port Configuration only)
The following interface attributes can be configured:
• Spanning Tree: Enables/disables spanning tree on a port.
