In the event of a server outage, or if you detect a system failure, you can automatically switch to the fallback mode on a device. The fallback mode determines how a device manages traffic on each segment in the event of a system failure.
You can switch the fallback mode on the device from your mobile phone or tablet.

Procedure

  1. Select a device on the SMS web management console.
  2. Set the fallback mode to On.
    When a device is in fallback mode, it either permits or blocks all traffic on each segment, depending on the segment action setting. When a device is in fallback, any traffic allowed through the device is not inspected; it simply passes through the device.
    You cannot switch the fallback mode if the device is unable to communicate with the SMS.
  3. Select Confirm.
  4. To remove the fallback mode on a device, set the mode to Off.
