Long Specifies a range of
Bridge Settings
Priority Specifies the bridge priority value. When switches or bridges are running STP, each is assigned a priority. After exchanging BPDUs, the device with the lowest priority value becomes the Root Bridge. The default value is 32768. The value must be a multiple of 4096. For example, 4096, 8192, 12288, etc. The range is 0 to 65535.
Hello Time Specifies the device Hello Time. The Hello Time indicates the amount of time in seconds a root bridge waits between configuration messages. The default is 2 seconds. The range is 1 to 10 seconds.
Max Age Specifies the device Maximum Age Time. The Maximum Age Time is the amount of time in seconds that a bridge waits before sending configuration messages. The default is 20 seconds. The range is 6 to 40 seconds.
Forward Delay Specifies the device forward delay time. The Forward Delay Time indicates the amount of time in seconds a bridge remains in a listening and learning state before forwarding packets. The default is 15 seconds. The range is 4 to 30 seconds.

The STP Port Settings screen allows network administrators to assign STP settings to specific interfaces.

Interface Indicates the port or LAG on which STP is enabled. Select either Port (default) or LAG, then select the interface from the
Enable STP Select this to enable STP on the port. The default is Enabled.
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
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 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, but can learn new MAC addresses.
•Forwarding The port is in Forwarding mode. The port can forward traffic and learn new MAC addresses.
Speed Displays 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. The default value is 2000000 for a 10M port, 200000 for a 100M port, and 20000 for a 1G port or a LAG.
Default Path Cost When selected the default path cost is implemented. The default is unselected.
Priority Priority value of the port. This value influences the port choice when a bridge has two ports connected in a loop. The range of values is 0
Designated Bridge ID Displays the bridge priority and the MAC Address of the designated bridge.
Designated Port ID Displays the selected port’s priority and interface.
Designated Cost Displays 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.
Forward Transitions Displays the number of times the port has changed from the Blocking state to Forwarding state.
