Scanning Access Points

Active scanning occurs when the security appliance starts up. When you request a scan after start-up, the wireless clients are interrupted for a few seconds. The scan can effect traffic in the following ways:

• Non-persistent, stateless protocols (such as HTTP) should not exhibit any ill-effects.
• Persistent connections (protocols such as FTP) are impaired or severed.
• WiFiSec connections should automatically re-establish and resume with no noticeable interruption to the client.

Clicking Scan All causes all active wireless clients to be disconnected while the scan is performed. If service interruption is a concern, you should not request a scan while the SonicWall security appliance is in Access Point mode. Wait until no clients are active or a short interruption in service is acceptable.

To perform a scan

1. Navigate to the DEVICE | Access Points > IDS page.
2. In the View Style: Access Point drop-down menu (at the top of the table), select All Access Points to scan all devices or choose a specific access point to scan only one device.

3. At the top of the table:

   • If you are scanning all access points, click Scan All.

   • If you are scanning only one access point, select the access point from the View Style: Access Point drop-down menu and then perform the scan.

     .

4. Confirm that you want to perform the scan.
