Description
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.
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.
Spanning Tree Protocol administrative mode associated with the port or port
channel. Possible values are Enable or Disable.
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
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.
Root bridge for the selected MST instance. It is made up using the bridge priority
and the base MAC address of the bridge.
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.
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.
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.
