Spanning Tree Tab - STP Port Settings
WebView Switches
• Long. Specifies 1 through 200,000,000 range for port path costs.The default path costs assigned to an
interface varies according to the selected method.
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 port priority value is provided in increments 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 indicates the amount of time in
seconds a bridge waits before sending configuration messages. The default max age 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.
Spanning Tree Tab - STP Port Settings
Network administrators can assign STP settings to specific interfaces using the STP Interface Settings screen.
The STP Interface Settings page contains the following fields:
Interface. Indicates the port or LAG on which STP is enabled.
STP. 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.
