SummaryThe If you see any problems on the Sensor with If there are task failures on the management modules within the Sensor that prevent alerts and packet logs from being captured, the Sensor is unable to recover. Also, if tasks are suspended on internal processors and become unresponsive, the Sensor doesn't reboot. The Sensor drops traffic if the traffic is directed to those failed or unresponsive internal processors. Technical Support might ask to look at the Sensor before you reboot it to clear the internal error. This command is often used in association with Layer 2 mode assert, so the Sensor can continue to process traffic while it's in the internal error condition. Layer 2 Mode: When the Sensor is placed in the Layer 2 mode, the Sensor does not reboot. The only exceptions to this rule are if the Sensor encounters a hardware failure, or if there's a task failure on the management module. Layer 2 mode makes sure that the traffic flowing through the Sensor isn't impacted. The Sensor continues to copy packets in and out of the port pairs and doesn't send them to the internal processors. You can turn on the Layer 2 mode from the command-line interface on the Sensor. NOTE: The command Affected ProductsLanguages:This article is available in the following languages: |
