- Enable NTP on both ExtremeCloud Appliances, go to Administration>System>Network time, and select NTP
- On the primary XCA, go to Administration>System Availability, and select paired.
- Configure the following parameters:
- Peer IP address: the data port IP address on the second XCA
- Auto AP balancing: select Active-Active or Active-Passive
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. Distribution of home/foreign relationship is decided by the controllers, there is no manual control.
- In an Active-Active configuration, approximately half of the APs establish an active tunnel to the local (primary) appliance. The remaining APs establish an active tunnel to the foreign (backup) appliance, spreading the load across the Availability Pair.
- In an Active-Passive configuration, all APs establish an active tunnel to the local (primary) appliance. The foreign (secondary) appliance is used for failover only.
In either configuration, most parameters can be configured on either appliance in the availability pair.
