A transport node is a node that is capable of participating in an NSX-T overlay or NSX-T VLAN networking. Any node can serve as a transport node if it contains a hostswitch. Such nodes include but are not limited to NSX Edges. This procedure demonstrates how to add an NSX Edge as a transport node.

About this task

An NSX Edge can belong to one overlay transport zone and multiple VLAN transport zones. If a VM requires access to the outside world, the NSX Edge must belong to the same transport zone that the VM's logical switch belongs to. Generally, the NSX Edge belongs to at least one VLAN transport zone to provide the uplink access.

Note:

If you plan to create transport nodes from a template VM, make sure that there are no certificates on the host in /etc/vmware/nsx/. The netcpa agent does not create a new certificate if a certificate already exists.

Prerequisites

  • The NSX Edge must be joined with the management plane, and MPA connectivity must be Up on the Fabric > Edges page. See Join NSX Edge with the Management Plane.

  • Transport zones must be configured.

  • An uplink profile (hostswitch profile) must be configured, or you can use the default uplink profile for bare-metal NSX Edge nodes.

  • An IP pool must be configured, or DHCP must be available in the network deployment.

  • At least one unused physical NIC must be available on the host or NSX Edge node.

Procedure

  1. From a browser, log in to an NSX Manager at https://<nsx-mgr>.
  2. Select Fabric > Nodes > Transport Nodes and click Add.
  3. Enter the following information:, the IP address, the name of the hostswitch, the uplink profile, the IP pool (or select DHCP), and the physical NIC information.
    • Enter a name for the NSX Edge transport node

    • Select an NSX Edge fabric node from the drop-down list.

    • Select transport zones. Generally, an NSX Edge transport node belongs to at least two transport zones: 1) Overlay for NSX-T connectivity and 2) VLAN for uplink connectivity.

    • Enter a name for the hostswitch. The edge switch name (sometimes called a hostswitch name). The edge switch names must match the names that you configured when you created the transport zones.

    • Select the uplink profile.

    • Select an IP pool for the overlay hostswitch. For VLAN hostswitches, leave the IP Pool field blank. No overlay tunnel endpoint IP address is needed because overlay hostswitches are for uplink VLAN traffic only.

    • Select the virtual NIC and uplink. Notice that unlike a host transport node, which uses vmnicX as the physical NIC, an NSX Edge transport node uses fp-ethX.

    • Select the uplink. The available uplinks depend on the configuration in the selected uplink profile.

When the transport node creation is successful, LCP Connectivity changes to Up on Fabric > Nodes > Edges. You might need to reload the browser screen to see this change.
