Before we jump into configuring transport zones, let's look at configuring VXLAN, which is part of preparing a cluster. VXLAN allows for layer 2 logical switching across hosts and can span multiple layer 3 domains. VXLANs are configured on a per-cluster basis, where each cluster that is to participate in NSX is mapped to a virtual distributed switch (VDS). All hosts in that cluster are then enabled for logical switches.
If you only plan to use the distributed firewall feature of NSX, you do not need to configure VXLAN transport layer.
When you configure VXLAN networking, you must provide a vSphere distributed switch, a VLAN ID, an MTU size, an IP addressing mechanism (DHCP or IP pool), and a NIC teaming policy.
Jumbo frames are necessary, so the MTU for each switch must be set to 1550 or higher. By default, it is set to 1600.
To configure VXLAN, follow these steps:
