Redundancy Select this option to turn on redundancy between a pair of NXC-8160s. You can
deploy one NXC-8160 as the main device and the other as the standby one.
Set switch as When you have two NXC-8160s in the network, select Main to have this NXC-8160
act as the active WLAN controller and set another NXC-8160 as the backup WLAN
controller. Otherwise, select
Standby and this NXC-8160 will function as a backup.
The backup WLAN controller periodically tests the connections to the main WLAN
controller and the referenced host. If the connection to the main WLAN controller is
down and the connection to the referenced host is up, the backup WLAN controller
becomes active automatically.
If the main WLAN controller fails, wireless clients can automatically connect to the
backup WLAN controller.
