Using System Diagnostics

Check Network Settings, at DEVICE | Diagnostics > Check Network Settings. is a diagnostic tool that automatically checks the network connectivity and service availability of several predefined functional areas of the NSv Series, returns the results, and attempts to describe the causes if any exceptions are detected. This tool helps you locate the problem area when users encounter a network problem.

Specifically, Check Network Settings automatically tests the following functions:

• Default Gateway settings

• DNS settings

• MySonicWall server connectivity

• License Manager server connectivity

• Content Filter server connectivity

To use the Check Network Settings tool, first select it in the Diagnostics drop-down menu and then click the check box in the row for the item that you want to test. The results are displayed in the same row. A green check mark signifies a successful test, and a red X indicates that there is a problem.

To test multiple items at the same time, select the Server checkbox at the top of the table to select all items or select the checkbox for each desired item and then click TEST ALL SELECTED.

If the probes fail, you can click the arrow to the left of the IP Address field of the failed item to jump to the configuration page to investigate the root cause.
