Displaying Interface Settings

The STA Port Information and STA Trunk Information pages display the current status of ports and trunks in the Spanning Tree.

Field Attributes

•Spanning Tree – Shows if STA has been enabled on this interface.

•STA Status – 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.

The rules defining port status are:

-A port on a network segment with no other STA compliant bridging device is always forwarding.
