NSX-T Data Center has several default IP Discovery segment profiles. You can also create additional ones.
IP Discovery is the central infrastructure in NSX-T Data Centerwhich determines the set of IP addresses that are associated with a port in the system. IP Discovery policies are applied via the Segment IP Discovery Profile which is configurable from the Policy Manager. It can be associated with a segment, segment port or a group. See Configure IP Discovery Segment Profile on Groups. When a segment or segment port is created, it is initially assigned a Default Segment IP Discovery Profile with a predefined set of policies.
