To ensure management changes are always made on the Primary NetScaler in a high availability (HA) pair, you should connect to the shared HA NSIP (NetScaler IP address). The shared HA NSIP is always aligned with the primary node in the HA pair, allowing consistent management changes. Other options like enabling management access to a SNIP or Cluster IP (CLIP) address do not specifically address ensuring you are always managing the Primary NetScaler.
