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.
