Configure a secondary NIC to access NetScaler Console

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