SonicWALL 5.8.1 Manuale Utente

The Interface Rank does not specify the operation that will be performed on the individual 
member. The operation that will be performed is specified by the Group Type. 

When Logical probing is enabled, test packets can be sent to remote probe targets to verify 
WAN path availability. A new option has been provided to allow probing through the additional 
WAN interfaces: Alternate WAN #3 and Alternate WAN #4.

VLANs for alternate WANs do not support QoS or VPN termination.

To configure the probing options for a specific Group, click the Configure icon of the Group 
you wish to configure on the Network > Failover & LB page. Then, click the Probing tab.

The Probing tab allows the user to modify the following settings:

Check Interface—The interval of health checks in units of seconds

Deactivate Interface—After a series of failed health checks, the interface sets to “Failover”

Reactivate Interface—After a series of successful health checks, the interface sets to 
“Available”

Probe responder.global.sonicwall.com on all interfaces in this group—Enable this 
checkbox to automatically set Logical/Probe Monitoring on all interfaces in the Group. 
When enabled, this sends TCP probe packets to the global SNWL host that responds to 
SNWL TCP packets, responder.global.sonicwall.com, using a target probe destination 
address of 204.212.170.23:50000. Once this checkbox is selected, the rest of the probe 
configuration will automatically enable built-in settings. The same probe will be applied to 
all four WAN Ethernet interfaces. Note that the Dialup WAN probe setting also defaults to 
the built-in settings.
