• Interface Indicates the port or LAG on which STP is enabled
• STP which indicates if STP is enabled on the port
• Port Fast Indicates if Fast Link is enabled on the port. If Fast Link mode is enabled for a port,
the Port State is automatically placed in the Forwarding state when the port link is
up. Fast Link optimizes the STP protocol convergence. STP convergence can take
30-60 seconds in large networks.
• Port State Displays 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, indicates that STP is currently disabled on the port. The port
forwards traffic while learning MAC addresses.
• Blocking, where indicates that the port is currently blocked and cannot
forward traffic or learn MAC addresses. Blocking is displayed when Classic
STP is enabled.
• Listening, where indicates that the port is in Listening mode. The port cannot
forward traffic nor can it learn MAC addresses.
• Learning, where indicates that the port is in whose mode. The port cannot
forward traffic, however it can learn new MAC addresses.
• Forwarding, the port that can forward traffic and learn new MAC addresses.
• Speed Indicates the speed at which the port is operating
• Path Cost Indicates the port contribution to the root path cost. The path cost is adjusted to a
higher or lower value, and is used to forward traffic when a path being rerouted.
Value Rage : 1-20000000
Default Path Cost - The default path cost of the port is automatically set by the
port speed and the default path cost method. The default values for path costs are:
- Ethernet - 2000000
- Fast Ethernet - 200000
- Gigabit Ethernet - 20000
• Default Path Cost When selected the default path cost is implemented
• Priority Indicates priority value of the port. The priority value influences the port choice
when a bridge has two ports connected in a loop. The priority value is between 0
-240. The priority value is provided in increments of 16.
• Designated Bridge
ID
Indicates the bridge priority and the MAC Address of the designated bridge.
• Designated Port ID Indicates the selected port’s priority and interface.
• Designated Cost Where indicates 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.
