The following table describes the read-only MST port configuration information displayed on
the Spanning Tree CST Configuration page.
Table 32. MST port status information
Field Description
Auto Calculated Port Path
Cost
Displays whether the path cost is automatically calculated (Enabled) or not
(Disabled). Path cost is calculated based on the link speed of the port if the
configured value for Port Path Cost is 0.
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 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 as follows:
• Disabled . STP is currently disabled on the port. The port forwards traffic
while learning MAC addresses.
• Blocking . The port is currently blocked and cannot be used to forward
traffic or learn MAC addresses.
• Listening . The port is currently in the listening mode. The port cannot
forward traffic nor can it learn MAC addresses.
• Learning . The port is currently in the learning mode. The port cannot
forward traffic. However, it can learn new MAC addresses.
• Forwarding . The port is currently in the forwarding mode. The port can
forward traffic and learn new MAC addresses
Port Role Each MST bridge port that is enabled is assigned a port role for each spanning
tree. The port role is one of the following: Root, Designated, Alternate, Backup,
Master, 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.
View STP Statistics
You can view information about the number and type of bridge protocol data units (BPDUs)
transmitted and received on each port.
