Port Redundancy Failover
SonicWall provides multiple methods for protecting against loss of connectivity in the case of a link failure, including High Availability (HA), Load Balancing Groups (LB Groups), and now Port Redundancy. If all three of these features are configured on an appliance, the following order of precedence is followed in the case of a link failure:
- Port Redundancy
- HA
- LB Group
When Port Redundancy is used with HA, Port Redundancy takes precedence. Typically an interface failover causes an HA failover to occur, but if a redundant port is available for that interface, then an interface failover occurs, but not an HA failover. If both the primary and secondary redundant ports go down, then an HA failover occurs (assuming the secondary firewall has the corresponding port active).
When Port Redundancy is used with a LB Group, Port Redundancy again takes precedence. Any single port (primary or secondary) failures are handled by Port Redundancy just like with HA. When both the ports are down then LB kicks in and tries to find an alternate interface.
