Enabling and Configuring Node Affinity
Node affinity enables administrators to manually configure the controller nodes to which APs will
connect.
To do this, set the order of preferred nodes on the node affinity page. Node affinity is implemented
at the AP zone level, which means that all APs that belong to a zone will have the same node
affinity settings.
If you want APs that belong to the same zone to connect to the same node whenever possible,
you can configure set the preferred node for a particular zone.
NOTE: Enabling node affinity automatically disables cluster redundancy.
Follow these steps to enable and configure node affinity.
1. Go to Configuration > System .
2. Under General System Settings, click Node Affinity.
3. Select the Enable Node Affinity check box, and then click Apply.

An affinity profile defines the order of the nodes to which APs that belong to the same zone
will connect.

Profile section.
The Edit Node Affinity Profile form appears and displays all nodes that belong to the
cluster.

5. In the Node Affinity Setting section, set the number of times an AP will attempt to connect
to the preferred node.
The default value is 3 and the accepted range is 1 to 10. If the AP is unable to connect to
the preferred node, it will attempt to connect to the node that is next in the order of node
priority.
6. In the Zone Assignment section, set the node affinity profile that you want each zone to use.
