SonicWALL TZ 190 Manuale Utente

Active scanning occurs when the wireless security appliance starts up, and at any time Scan 
Now is clicked at the bottom of the Discovered Access Points table. When the wireless 
security appliance is operating in a Bridge Mode, the Scan Now feature does not cause any 
interruption to the bridged connectivity. When the wireless security appliance is operating in 
Access Point Mode, however, a temporary interruption of wireless clients occurs for no more 
than a few seconds. This interruption manifests itself as follows: 

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.

The Scan Now feature causes a brief disruption in service. If this is a concern, wait and use 
the Scan Now feature at a time when no clients are active, or the potential for disruption 
becomes acceptable.

Access Points detected by the wireless security appliance are regarded as rogues until they 
are identified to the wireless security appliance as authorized for operation. To authorize an 
access point, select it in the list of access points discovered by the wireless security appliance 
scanning feature, and add it clicking the Authorize icon
