Configuring the Instance for Connection Migration

Aug 09, 2017

In your network setup, if you expect connection migration between the routers, then you must configure the layer 4 parameters and make changes to the VLAN configurations, appropriately.

  • Configure Layer 4 Parameters

    If you have two routers and expect connection migration between the routers, you must configure layer 4 parameters on the NetScaler instance.

    To configure layer 4 parameters from the configuration utility
