Availability Pair Settings

Table 1. Availability Pair Settings
Field	Description
Peer IP Address	Physical VLAN address of the paired appliance. This is the IP address of the "Physical 1" interface (port esa0), which matches the VLAN definition under System > Interfaces.
Role	Select the role of the paired appliance. Valid values are Primary or Backup. Note: The configuration of the Primary appliance is copied to the Secondary appliance.
Auto AP Balancing	Select the load balancing configuration for the availability pair. In an availability pair, an AP establishes an active tunnel to one appliance and a backup tunnel to the other appliance. The active tunnel is used to pass the client data over tunneled topologies. In an Active-Active configuration, approximately half of the APs establish an active tunnel to the primary appliance. The remaining APs establish an active tunnel to the backup appliance, spreading the load across the availability pair. In an Active-Passive configuration, all APs establish an active tunnel to the primary appliance. The secondary appliance is used for failover only.
