Configure a secondary NIC to access NetScaler® ADM

Last published : Sep 21, 2026
You can configure a second NIC for isolating management access to NetScaler ADM. Using this second NIC feature, depending upon your requirement, you can choose how you want to isolate the traffic that is received and sent through the NetScaler ADM.
Consider a scenario in which you want to isolate the traffic to:
  • Have all communications between NetScaler ADM and its managed NetScaler instances in one network.
  • Have management access to NetScaler ADM in another network.
In this scenario, as an administrator, you can:
  • Configure one IP address for the traffic between NetScaler ADM and its managed NetScaler instances.
  • Configure another IP address for managing the NetScaler ADM software to perform all administrative tasks in the software.
Note
If NetScaler ADM is configured as an HA pair, the management IP address configured on the second NIC is associated with the primary node.
