GS700TS Smart Switch Software Administration Manual
The CST Port Configuration screen contains the following fields:
•Interface – Displays the port or LAG for which the STP information is displayed.
•STP Status – Select the STP status on the interface. The possible field values are:
–Enable – Enables STP on the interface. This is the default.
–Disable – Disables STP on the interface.
•Fast Link – Select the Fast Link state on the interface. If Fast Link mode is enabled for a interface, the Port State is automatically placed in the Forwarding state when the port link is up. Fast Link optimizes the STP protocol convergence. The possible field values are:
–Enable – Enables Fast Link on the interface.
–Disable – Disables Fast Link on the interface. This is the default.
•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:
–Forwarding – Indicates STP is enabled on the port, and the port is forwarding packets based on the STP topology.
–Disabled – Indicates STP is currently disabled on the port. The port forwards traffic while learning MAC addresses.
–Blocking – Indicates the port is currently blocked and cannot forward traffic or learn MAC addresses.
–Listening – Indicates the port is in Listening mode. The port cannot forward traffic nor can it learn MAC addresses.
–Learning – Indicates the port is in Learning mode. The port cannot forward traffic, however it can learn new MAC addresses.
•Speed – Displays the speed at which the port is operating.
•Path Cost – Enter the method used to assign default path cost to STP ports. The possible field range is 1 - 200000000. The default path cost assigned to an interface varies according to the selected CST configuration method (Hello Time, Max Age or Forward Delay).
•Priority – Select the port priority value. When switches or ports are running STP, each is assigned a priority. After exchanging BPDUs, the device with the lowest priority value becomes the Root Port. The port priority has a range of
