Parameter | Default | Description |
Spanning Tree | Enabled | Enable this parameter to participate in an STA |
Protocol |
| compliant network. |
Priority | 32,768 | Device priority is used in selecting the root device, |
|
| root port, and designated port. The device with |
|
| the highest priority becomes the STA root device. |
|
| However, if all devices have the same priority, the |
|
| device with the lowest MAC address will then |
|
| become the root device. |
|
| Enter a value from 0 - 65535. |
|
| Remember that the lower the numeric value, the |
|
| higher the priority. |
Hello Time | 2 | Time interval (in seconds) at which the root device |
|
| transmits a configuration message. |
|
| The minimum value is1. |
|
| The maximum value is |
|
| the lower of 10 or [(Max. Message Age / 2) |
Max (Message) Age | 20 | The maximum time (in seconds) a device can wait |
|
| without receiving a configuration message before |
|
| attempting to reconfigure. All device ports (except |
|
| for designated ports) should receive configuration |
|
| messages at regular intervals. Any port that ages |
|
| out STA information (provided in the last |
|
| configuration message) becomes the designated |
|
| port for the attached LAN. If it is a root port, a new |
|
| root port is selected from among the device ports |
|
| attached to the network. |
|
| The minimum value is |
|
| the higher of 6 or [2 x (Hello Time + 1)]. |
|
| The maximum value is |
|
| the lower of 40 or [2 x (Forward Delay - 1)]. |
Forward Delay | 15 | The maximum time (in seconds) the root device |
|
| will wait before changing states (i.e., listening to |
|
| learning to forwarding). This delay is required |
|
| because every device must receive information |
|
| about topology changes before it starts to forward |
|
| frames. In addition, each port needs time to listen |
|
| for conflicting information that would make it |
|
| return to a blocking state; otherwise, temporary |
|
| data loops might result. |
The maximum value is 30. The minimum value is
the higher of 4 or [(Max. Message Age / 2) + 1].
