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.
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 3-112 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 – 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 STA on this interface. (Default: Enabled).
• Priority – Defines the priority used for this port in the Spanning Tree Protocol. If
the path cost for all ports on a switch are the same, the port with the highest priority
(i.e., lowest value) will be configured as an active link in the Spanning Tree. This
makes a port with higher priority less likely to be blocked if the Spanning Tree
