Adoption Preference

ExtremeCloud IQ Controller supports the ability to specify an appliance adoption preference and to support a High-Availability pair of appliances located in separate data centers. APs assigned to a site will discover the appliance specified in the Adoption Preference. The load assignment for the preferred appliance persists. However, you can re-map the AP-to-site preference at any time, to adjust for experience, business needs, or network conditions.

For Adoption Preference, select the preferred connection point for APs that are assigned to this site. Possible values are:

Use Global Settings

The global settings are dependent on the Availability setting Auto AP Balancing (which is located under Administration > System > Availability).

When Auto AP Balancing is Active - Active, which spreads the load across the availability pair, the Use Global Settings field displays Load Balance.
When the Auto AP Balancing is Active - Passive, which uses the secondary appliance for failover only, the Use Global Settings field displays Primary Appliance.

For more information about the load balancing configuration for an availability pair, see Availability Pair Settings.

Primary Appliance

APs for this site will be homed on the primary appliance.

Backup Appliance

APs for this site will be homed on the secondary appliance. The secondary appliance is used for load balancing or failover support.

Adoption Preference is also an override configuration setting for one or more APs:

To configure the Adoption Preference for a single AP, refer to Advanced Setting Overrides.
To configure the Adoption Preference for multiple APs, refer to AP Actions.

Note

The Tunnel column on the Access Point List displays which controller the AP has an active tunnel to. Possible values are:

Primary — The AP has an active tunnel to the primary controller in an availability pair.
Backup — The AP has an active tunnel to the secondary controller in an availability pair.
N/A — Indicates that an active tunnel does not exist or that there is a configuration entry for the AP, but the AP is not currently connected.
