4. In the Bridge Port column, click on the Bridge Port number to configure bridge
port parameters. The Spanning Tree Port Configuration dialog box opens.
5. Use Table 12-6 to configure Spanning Tree Bridge Port Information parameters:
State Current bridging state of the port.
The options are:
• Disabled - The port is disabled.
• Blocking - The Spanning Tree algorithm has set this port’s
state to block, meaning that it is enabled, but not passing
traffic.
• Listening - The port is in a transitional state, waiting for the
spanning tree algorithm to determine whether it should
block or forward traffic.
• Learning - The port is learning MAC addresses, but not yet
forwarding traffic.
• Forwarding - This port has been selected by the Spanning
Tree algorithm to forward traffic, and is forwarding traffic
currently.
• Down - The port’s physical port has no link detected.
Designated Root Displays the Root bridge for this spanning tree.
Designated Bridge The bridge identifier for the bridge considered to be the
designated bridge for this segment.
Designated Port The port identifier of the port on the designated bridge for this
segment of the spanning tree.
Designated Cost The path cost of the designated root of the segment connected to
this port.
Forward
Transitions Number of times that this port has transitioned from blocking to
forwarding.
Table 12-6. Spanning Tree Bridge Port Information Parameters
Parameter Definition
Enable Sets whether or not spanning tree is active on this bridge port.
Priority Sets the port’s priority in the spanning tree algorithm. A port
with a higher priority (lower priority number) is more likely to
be chosen as the primary path in the spanning tree.
