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 modified, and the Running Configuration file
is updated.
