SZ-144 Under Ruckus GRE - what is Tunnel Failover?

[Greg_WiGuy]

I see this option in the administrator guide but can't find an actual description of what it does.  I know the AP tunnels will swap between data-planes if one can't be contacted, so what does enabling tunnel failover do?

Running 2 x SZ-144 in a cluster with some tunneled SSIDs.

Hi Greg,

After the access point (AP) establishes the SSH tunnel to the controller (or cluster), the AP receives a list of data plane IP addresses (or data interface IP addresses of the virtual data plane). The AP then establishes the Ruckus GRE tunnel with the first IP address in the list. When a controller goes down, the AP maintains the same tunnel with the data plane until the data plane goes down
