DESCRIPTION
Select Enabled to turn on redundancy between a pair of NXC-8160s. You can
deploy one NXC-8160 as the main controller and the other as the backup one.
Otherwise, select Disabled.
When you have two NXC-8160s in the network, select Main to have this NXC-8160
acts 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.
Enter the IP address of the other WLAN controller.
Eenter the IP address of a reliable nearby computer to have the NXC-8160 ping that
address and test the connection to the LAN.
The NXC-8160 tests the connection by periodically sending a ping to the address in
the Reference IP field.
Select a number of seconds to set the time interval between checks. Allow more
time if your destination IP address handles lots of traffic.
Select the number of the lost packets that can be allowed before the the connection
is considered "down" (not connected).
