Note the id code of your Default host cluster. This code identifies this host cluster in relation to other resources of your virtual environment.
The Default cluster is associated with the Default data center through a relationship using the id and href attributes of the data_center element.
The networks sub-collection contains a list of associated network resources for this cluster. The next section examines the networks collection in more detail.
