You can activate DHCP for networks backed by NSX-T Data Center in network mode and directly associate a DHCP service with an organization VDC network.

The DHCP service of an organization VDC network provides IP addresses from its address pool to VM NICs that are configured to request an address from DHCP. The service provides the address when the virtual machine powers on.

Prerequisites

  • Verify that the organization VDC network for which you want to activate DHCP in network mode is either isolated or routed. Use DHCP network mode for a routed network if you plan to detach the network from the edge gateway with which it is associated.

  • Verify that you are an organization administrator, system administrator, or that you are assigned a role that includes an equivalent set of rights.

  • Verify that your system administrator assigned an NSX-T Data Center service edge cluster to the organization VDC in which the organization VDC network is deployed.
