Supportability matrix for NetScaler cluster

August 10, 2026
Contributed by:

Clustering in the NetScaler appliance supports a wide-spread of features in NetScaler configurations.

The following table lists the NetScaler features and provides the supportability status across different NetScaler releases of cluster setups. The supportability status of some NetScaler features in a NetScaler BLX™ cluster is different than a NetScaler non-BLX (MPX, or VPX, SDX ADC) cluster.

Important

The “Node-level” entry in the table indicates that the feature is supported only on individual cluster nodes.
