The IP address of a virtual machine can be detected by VMware Tools, which are installed on the VM, or by DHCP snooping and ARP snooping, which are enabled on the host cluster. These IP discovery methods can be used together in the same NSX installation.


  1. In the vSphere Web client, navigate to Networking & Security > Installation > Host Preparation.
  2. Click the cluster you want to change, then click Actions () > Change IP Detection Type.
  3. Select the desired detection types and click OK.
