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 – Enable STP on the interface.
– Disable – Disable 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 – Enable Fast Link on the interface.
– Disable – Disable Fast Link on the interface.
• 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 – STP is enabled on the port, and the port is forwarding packets based on
the STP topology.
– Disabled – STP is currently disabled on the port. The port forwards traffic while
learning MAC addresses.
– Blocking – The port is currently blocked and cannot forward traffic or learn MAC
addresses.
– Listening – The port is in Listening mode. The port cannot forward traffic nor can it
learn MAC addresses.
– Learning – 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 0-240 in increments of 16. The
default value is 128.
2. Select the STP Status and Fast Link status in the provided fields.
