Figure 101: Configuring 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.
