To use Gateway DHCP server for a dynamic IP assignment, you must attach a DHCP server profile to a tier-0 or tier-1 gateway.

You can attach a DHCP profile to a gateway only when the segments connected to that gateway do not have a Local DHCP server or a DHCP relay configured on them. If a Local DHCP server or DHCP relay exists on the segment, the UI throws an error when you try to attach a DHCP profile to the gateway. You must disconnect the segments from the gateway, and then attach a DHCP profile to the gateway.

Prerequisites

A DHCP server profile is added in the network.

Procedure

  1. From your browser, log in with admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
  2. Go to Networking > Tier-0 Gateways or Networking > Tier-1 Gateways.
  3. Edit the appropriate gateway.
  4. Next to DHCP, click Set DHCP Configuration.
  5. In the Type drop-down menu, select DHCP Server.
  6. Select a DHCP server profile to attach to this gateway.
  7. Click Save.

What to do next

Navigate to Networking > Segments. On each segment that is connected to this gateway, configure the DHCP settings, DHCP options, and static bindings.
