3.1.5 Displaying Interface Settings
The STA Port Information and STA Trunk Information pages display the 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.
•
If two ports of a switch are connected to the same segment and there is no other STA device attached
to this segment, the port with the smaller ID forwards packets and the other is discarding.
•
All ports are discarding when the switch is booted, then some of them change state to learning, and
then to forwarding.
