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.

Procedure

  1. From your browser, log in with admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
  2. Select Advanced Networking & Security > Networking > Switching > Switching Profiles > Add.
  3. Select IP Discovering and specify the IP Discovery switching profile details.
    Option Description
    Name and Description Enter a name and optionally a description.
    ARP Snooping For an IPv4 environment. Applicable if VMs have static IP addresses.

What to do next

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 or Associate a Custom Profile with a Logical Port.
