Parameter | Default | Description |
Max | 20 | The maximum time (in seconds) a device can wait |
(Message) 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 | 15 | The maximum time (in seconds) the root device will |
Delay |
| 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.
Maximum value is 30.
Minimum value is the higher of
4 or [(Max. Message Age / 2) + 1].
