LABEL	DESCRIPTION
Redundancy

Redundancy	Select Enabled to turn on redundancy between a pair of NXC-8160s. You can
Status	deploy one NXC-8160 as the main controller and the other as the backup one.
	Otherwise, select Disabled.

Main/Standby	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.

Monitored IP	Enter the IP address of the other WLAN controller.

Reference IP	Eenter the IP address of a reliable nearby computer to have the NXC-8160 ping that
	address and test the connection to the LAN.

Keep Alive	The NXC-8160 tests the connection by periodically sending a ping to the address in
Interval (ms)	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.

Keep Alive	Select the number of the lost packets that can be allowed before the the connection
Check	is considered "down" (not connected).
