Configuring the Spanning Tree Protocol Defining Spanning Tree Interface Settings 13 - Flooding-Floods BPDU packets when Spanning Tree is disabled on an interface. • Path Cost-Set the port contribution to the root path cost or use the default cost generated by the system. • Priority-Set the priority value of the port. The priority value influences the port choice when a bridge has two ports connected in a loop. The priority is a value from 0 to 240, set in increments of 16. • Port State-Displays the current STP state of a port. - Disabled-STP is currently disabled on the port. The port forwards traffic while learning MAC addresses. - Blocking-The port is currently blocked, and cannot forward traffic (with the exception of BPDU data) or learn MAC addresses. - Listening-The port is in Listening mode. The port cannot forward traffic, and cannot learn MAC addresses. - Learning-The port is in Learning mode. The port cannot forward traffic, but it can learn new MAC addresses. - Forwarding-The port is in Forwarding mode. The port can forward traffic and learn new MAC addresses. • Designated Bridge ID-Displays the bridge priority and the MAC address of the designated bridge. • Designated Port ID-Displays the priority and interface of the selected port. • Designated Cost-Displays the cost of the port participating in the STP topology. Ports with a lower cost are less likely to be blocked if STP detects loops. • Forward Transitions-Displays the number of times the port has changed from the Blocking state to Forwarding state. • Speed-Displays the speed of the port. • LAG-Displays the LAG to which the port belongs. If a port is a member of a LAG, the LAG settings override the port settings. STEP 4 Click Apply. The interface settings are written to the Running Configuration file.

—Floods BPDU packets when Spanning Tree is disabled on an
interface.
Path Cost
—Set the port contribution to the root path cost or use the default

port choice when a bridge has two ports connected in a loop. The priority is
a value from 0 to 240, set in increments of 16.
Port State
—Displays the current STP state of a port.
-
Disabled
—STP is currently disabled on the port. The port forwards
traffic while learning MAC addresses.
-
Blocking
—The port is currently blocked, and cannot forward traffic (with
the exception of BPDU data) or learn MAC addresses.
-
Listening
—The port is in Listening mode. The port cannot forward traffic,
and cannot learn MAC addresses.
-
Learning
—The port is in Learning mode. The port cannot forward traffic,
but it can learn new MAC addresses.

traffic and learn new MAC addresses.
Designated Bridge ID
—Displays the bridge priority and the MAC address
of the designated bridge.
Designated Port ID
—Displays the priority and interface of the selected
port.
Designated Cost
—Displays the cost of the port participating in the STP
topology. Ports with a lower cost are less likely to be blocked if STP detects
loops.
Forward Transitions
—Displays the number of times the port has changed
from the
Blocking
state to
Forwarding
state.
Speed
—Displays the speed of the port.
LAG
—Displays the LAG to which the port belongs. If a port is a member of
a LAG, the LAG settings override the port settings.
