Clusters are divided into cluster groups that allow you to deploy and link agents in a way that conforms to your network topology. For example, you could create cluster groups for different regions of where your nodes and agents are physically located, which could minimize network traffic and control where your agents' connections occur.
Cluster child nodes must belong to a cluster group, and can only belong to one cluster group at a time. Agents in each cluster group only link to nodes in the same cluster group.
A cluster group is different from an agent group, which is a group of agents that you designate to scan a target. You use cluster groups to manage the nodes that agents link to within a cluster.
To manage your cluster groups and their assigned nodes and agents, see the following:
