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 3-123for 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.

Trunk14 – Indicates if a port is a member of a trunk.
