You can enable the ARP snooping or DHCP snooping to create a custom IP Discovery switching profile that learns the IP and MAC addresses to ensure the IP integrity of a logical switch.

Prerequisites

Familiarize yourself with the IP Discovery switching profile concept. See Understanding IP Discovery Switching Profile.

Procedure

  1. From your browser, log in to an NSX Manager at https://nsx-manager-ip-address.
  2. Select Switching > Switching Profiles from the navigation panel.
  3. Click Add.
  4. Complete the IP Discovery switching profile details.

    Option

    Description

    Name and Description

    Assign a name to the custom IP Discovery switching profile.

    You can optionally describe the setting you enabled in the profile.

    Type

    Select IP Discovering from the drop-down menu.

    ARP Snooping

    Toggle the ARP Snooping button to enable the feature.

    ARP snooping inspects the VM outgoing ARP and GARP to learn the VM MAC and IP addresses. ARP snooping is applicable if the VM uses a static IP address instead of DHCP.

    DHCP Snooping

    Toggle the DHCP Snooping button to enable the feature.

    DHCP snooping inspects the DHCP packets exchanged between the VM DHCP client and the DHCP server, to learn the VM MAC and IP addresses.

  5. Click Save.

Results

A custom IP Discovery switching profile appears as a link.

What to do next

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