Displaying Interface Settings for STA
Use the Spanning Tree > STA (Configure Interface - Show Information) page to
display the current status of ports or trunks in the Spanning Tree.
Parameters
These parameters are displayed:
◆
Spanning Tree – Shows if STA has been enabled on this interface.
◆
BPDU Flooding – Shows if BPDUs will be flooded to other ports when
spanning tree is disabled globally on the switch or disabled on a specific port.
◆
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.
