USING THE SYSTEM CONFIGURATION PROGRAM
Parameter | Default | Description |
Max (Message) | 20 | The maximum time (in seconds) a device can wait |
Age |
| 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].
