Configure IP Discovery Switching Profile in Manager Mode

NSX-T Data Center has several default IP Discovery switching profiles. You can also create additional ones.

Prerequisites

Familiarize yourself with the IP Discovery switching profile concepts. See Understanding IP Discovery Switching Profile.
Verify that Manager mode is selected in the NSX Manager user interface. See NSX Manager. If you do not see the Policy and Manager mode buttons, see Configure User Interface Settings.

From your browser, log in with admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
Select Networking > Logical Switches > Switching Profiles > Add.

Select IP Discovering and specify the IP Discovery switching profile details.

Attach this IP Discovery customized switching profile to a logical switch or logical port so that the modified parameters in the switching profile are applied to the network traffic. See Associate a Custom Profile with a Logical Switch in Manager Mode or Associate a Custom Profile with a Logical Port in Manager Mode.
