NetScaler appliances that you want to add to the cluster must satisfy the criteria specified in "Prerequisites for Cluster Nodes". Before actually setting up a cluster, you must be aware of cluster basics. For information, see "Cluster Overview".
Forming a cluster requires you to set up inter-node communication, create the cluster (by adding the first NetScaler appliance), and then add the other cluster nodes. Each of these steps is explained with relevant details in subsequent topics.
Note: While there are some differences in setting up an L2 and L3 cluster, there are many similarities too. The subsequent topics explain the setup for both cluster types while highlighting the configurations that are specific to L3 clusters.
