Restart Warnings for the Threat Defense Devices

When you deploy, the Inspect Interruption column in the deploy page specifies whether a deployed configuration restarts the Snort process on the threat defense device. When the traffic inspection engine referred to as the Snort process restarts, inspection is interrupted until the process resumes. Whether traffic is interrupted or passes without inspection during the interruption depends on how the device handles traffic. Note that you can proceed with the deployment, cancel the deployment and modify the configuration, or delay the deployment until a time when deploying would have the least impact on your network.

When the Inspect Interruption column indicates Yes and you expand the device configuration listing, the system indicates any specific configuration type that would restart the Snort process with an Inspect Interruption (). When you hover your mouse over the icon, a message informs you that deploying the configuration may interrupt traffic.

The following table summarizes how the deploy page displays inspection interruption warnings.

Inspection Interruption Indicators

Type	Inspect Interruption	Description
Threat Defense	Inspect Interruption ()Yes	At least one configuration would interrupt inspection on the device if deployed, and might interrupt traffic depending on how the device handles traffic. You can expand the device configuration listing for more information.
	--	Deployed configurations will not interrupt traffic on the device.
	Undetermined	The system cannot determine if a deployed configuration may interrupt traffic on the device. Undetermined status is displayed before the first deployment after a software upgrade, or in some cases during a Support call.
	Errors ()	The system cannot determine the status due to an internal error. Cancel the operation and click Deploy again to allow the system to redetermine the Inspect Interruption status. If the problem persists, contact Support.
sensor	--	The device identified as sensor is not the threat defense device; the system does not determine if a deployed configuration may interrupt traffic on this device.

For information on all configurations that restart the Snort process for all device types, see Configurations that Restart the Snort Process When Deployed or Activated.
