Working in Fallback Mode
The fallback mode (also known as backup configuration) operates the remote AP if the master controller or the
configured primary and backup LMS are unreachable. The remote AP saves configuration information that allows it
to operate autonomously using one or more SSIDs in local bridging mode while supporting open association or
encryption with PSKs. You can also use the backup configuration if you experience network connectivity issues, such
as the WAN link or the central data center becomes unavailable. With the backup configuration, the remote site
does not go down if the WAN link fails or the data center is unavailable.
