Device HA

Device HA lets a backup NXC automatically take over if the master NXC fails.

A

B

In this example, device B is the backup for device A in the event something happens to it and prevents it from managing the wireless network.

23.1 Device HA Overview

Management Access

You can configure a separate management IP address for each interface. You can use it to access the NXC for management whether the NXC is the master or a backup. The management IP address should be in the same subnet as the interface IP address.

Synchronization

Use synchronization to have a backup NXC copy the master NXC’s configuration, signatures (anti-virus, IDP/application patrol, and system protect), and certificates.

Only NXCs of the same model and firmware version can synchronize.

Otherwise you must manually configure the master NXC’s settings on the backup (by editing copies of the configuration files in a text editor for example).
