First management interface

In a clustered environment, the IP address of the first management interface is used as the node identifier. For this reason, a static IP address must be assigned to the first management interface of the appliance.

When you change the first management interface of a non-master node, the cluster is updated automatically.

We cannot change the IP address of the first management interface on a master. To change the first management interface on a master node, we must first demote the node from master. You can then promote the node to master again and update any external client references in the distributed session cache.
