Verifying HA Functionality

To verify that Primary and Backup SonicWALL security
appliances are functioning correctly, wait a few minutes, then
trigger a test failover by logging into the Primary unit and
powering it off. The Backup SonicWALL security appliance
should quickly take over. After a failover to the Backup
appliance, all the pre-existing network connections must be
re-established, including the VPN tunnels that must be
re-negotiated.
From your management workstation, test connectivity through
the Backup SonicWALL by accessing a site on the public
Internet. Note that unless virtual MAC is enabled, the Backup
SonicWALL will not assume the Ethernet MAC address.
Log into the Backup SonicWALL's unique LAN IP address. The
management interface should now display Logged Into:
Backup SonicWALL Status: (green ball) Active in the upper-
right-hand corner.
Now, power the Primary SonicWALL back on, wait a few
minutes, then log back into the management interface. If the
Backup SonicWALL is active, you can use the shared IP
address to log into it.
If you are using the Monitor Interfaces feature, experiment with
disconnecting each monitored link to ensure correct
configuration.
Multiple ISP / WAN Failover and Load
Balancing
WAN Failover and Load Balancing allows you to designate an
interface as a Secondary or backup WAN port.
The secondary WAN port can be used as a backup if the
primary WAN port is down and/or unavailable, or it can maintain
a persistent connection for WAN port traffic to divide outbound
traffic flows between the Primary fixed WAN port and the user-
assigned Secondary WAN port.
