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.

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 3-81for 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.
