Table 26 Spanning Tree Port Parameter Descriptions
Parameter Description
Priority (port) The Port Priority parameter helps determine which bridge port becomes
the designated port. In a network topology that has multiple bridge ports
connected to a single segment, the port with the lowest port priority
becomes the designated port for the segment.
Cost The Port Path cost parameter is used to help determine the designated port
for a segment. Generally speaking, the faster the port, the lower the path
cost. A setting of 0 indicates that the cost will be set to the appropriate
default after the link speed has been auto negotiated.
FastFwd The Fast Forward field shows whether the port is in Fast Forwarding
mode or not, which permits the port that participates in Spanning Tree to
bypass the Listening and Learning states and enter directly into the
Forwarding state.
State The State field shows the current state of the port. The state field can be
BLOCKING, LISTENING, LEARNING, FORWARDING, or DISABLED.
Designated Bridge The Designated Bridge shows information about the bridge connected to
each port, if applicable. Information includes the priority (in hexadecimal
notation) and MAC address of the Designated Bridge.
Designated Port The Designated Port field shows the port on the Designated Bridge to
which this port is connected.
