status {disable | The fail_bypass option is only available on the | disable |

fail_bypass} | When the FortiBridge detects an upstream or downstream |
|
network disconnection (whether due to a cut/disconnected |
| |
| cable, failure of the connected device, or failure of the |
|
| FortiBridge unit’s own interface), it will bring down its own |
|
| network interface after waiting the amount of time set for |
|
| the threshold variable. If the fail close status is set to |
|
| fail_close and a switch connected to EXT1 fails, the |
|
| FortiBridge would bring down its own INT1. This way, the |
|
| device connected to INT1 will be able to determine there is |
|
| a problem Similarly, if a device connected to INT1 fails, the |
|
| FortiBridge would bring down its own EXT1. |
|
| When the problem is corrected, the FortiBridge will enable |
|
| its own network interface after waiting the amount of time |
|
| set for the threshold variable. |

|
| by this hardware error when this command is invoked. This |
|
| is normal as hardware support for fail_close was only |
|
| added in later units. |
|
| When using a |
|
| equipment doesn’t properly detect the status of a |
|
| FortiBridge interface brought down by the fail_close |
|
| option. To prevent this problem, use fail_bypass |
|
| instead. If a network problem is detected with |
|
| fail_bypass set, the FortiBridge will switch to bypass |
|
| mode. This way, the network devices can detect the |
|
| problem directly through the FortiBridge. Note that |
|
| fail_bypass causes the FortiBridge to remove itself |
|
| from the network when a problem is detected so manual |
|
| intervention is required to switch back to normal mode. |

|
|
|
threshold | Enter how long, in seconds, the FortiBridge will wait after | 3 |
<seconds_integer> | detecting a network problem before activating the fail close |
|
| feature. Except when fail_bypass is set, the FortiBridge |
|
| will wait the specified time before deactivating the fail close |
|
| feature when the problem is corrected. |
