0. If you specify a number between 16 and 31, the priority is set to 16. It takes a value
in the range of 0–240.
• Port Path Cost. Set the Path Cost to a new value for the specified port in the selected
MST instance. It takes a value in the range of 1–200000000.
6. Click Cancel to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch
7. If you make any configuration changes, click Apply to send the updated configuration to the
switch. Configuration changes take place immediately.
The following table describes the read-only MST port configuration information displayed on
the Spanning Tree CST Configuration page.
Field Description
Auto-calculated Port Displays whether the path cost is automatically calculated (Enabled) or not
Path Cost (Disabled). Path cost is calculated based on the link speed of the port if the
configured value for Port Path Cost is zero.
Port ID The port identifier for the specified port within the selected MST instance. It is
made up from the port priority and the interface number of the port.
Port Up Time Since Time since the counters were last cleared, displayed in Days, Hours, Minutes, and
Counters Last Cleared Seconds.
Port Mode Spanning Tree Protocol Administrative Mode associated with the port or port
channel. Possible values are Enable or Disable.
Port Forwarding State Indicates the current STP state of a port. If enabled, the port state determines what
forwarding action is taken on traffic. Possible port states are:
• Disabled: STP is currently disabled on the port. The port forwards traffic while
• Blocking: The port is currently blocked and cannot be used to forward traffic or
• Listening: The port is currently in the listening mode. The port cannot forward
• Learning: The port is currently in the learning mode. The port cannot forward
• Forwarding: The port is currently in the forwarding mode. The port can forward
Port Role Each MST Bridge Port that is enabled is assigned a Port Role for each spanning
tree. The port role will be one of the following values: Root Port, Designated Port,
Alternate Port, Backup Port, Master Port, or Disabled Port.
Designated Root Root Bridge for the selected MST instance. It is made up using the bridge priority
and the base MAC address of the bridge.
Designated Cost Displays cost of the port participating in the STP topology. Ports with a lower cost
are less likely to be blocked if STP detects loops.
Designated Bridge Bridge Identifier of the bridge with the Designated Port. It is made up using the
bridge priority and the base MAC address of the bridge.
Designated Port Port Identifier on the Designated Bridge that offers the lowest cost to the LAN. It is
made up from the port priority and the interface number of the port.
