On encountering data path errors, the Sensor goes Layer 2 mode and tries to auto-recover. During a datapath error, the auto-recovery feature reboots the datapath threads without any interruption to traffic.
Note
The Sensor should be in good health and in Layer 2 mode for performing the auto-recovery.
If the recovery is successful, the Sensor comes out of Layer 2 mode. If the recovery is not successful, the Sensor remains in Layer 2 mode.
Syntax:
show autorecovery status
This command has no parameters.
By executing the command, the following status information is displayed:
| Status | Description |
|---|---|
| Auto-recovery enabled | The status of auto-recovery, whether it is On or Off. When the Layer 2 is enabled, this status will be displayed as On. |
| Auto-recovery attempts | Number of auto-recovery attempts made since last reboot |
| Last Auto-recovery status |
|
| Last Auto-recover time | The time when Sensor came out of Layer 2 due to successful auto-recovery |
Applicable to:
NS-series Sensors
Note
Auto-recovery is supported on Virtual IPS Sensors. However, a Virtual IPS Sensor cannot depend on its software to go to Layer 2 during recovery. So, the traffic is interrupted until all applications are restarted and the Sensor is back to good health.
