Creating a VIP to Switch Contents Between Two Layer 4 Ports

This topic explains creating one virtual service to switch contents between two Layer 4 ports. Use the Layer 4 port switching feature on a Layer 4 virtual service if there are two VIPs listening on two different ports.

To create a single virtual service listening to two different ports (port X and port Y), create two pools – pool-X and pool-Y and add the servers to these pools.

Log into the NSX Advanced Load Balancer CLI and use the configure virtualservice <virtual-service name> to map one virtual service to two pools listening on two different ports.

Note:

This option is only supported through the CLI.

Creating a virtual service, and a pool to listen to port number X:
