+= Managing a hub cluster by using {cim}
+
+Importing and managing a hub cluster by using {cim} can simplify your cluster management by providing a single point of control. You can also configure additional options, such as the hub cluster Kube API server verification strategy.
+
+By default, {cim} does not automatically manage your hub cluster. Enable the feature to add and manage additional hosts on the hub cluster by using {cim}.

++
+[source,bash]
+----
+oc annotate agentserviceconfig agent agent-install.openshift.io/enable-local-cluster-import=true 
+----
++
+Verify that the feature is enabled by checking if an `InfraEnv` custom resource is created for the `local-cluster`. Run the following command:

+[source,bash]
+----
+oc get infraenv -n multicluster-engine
