Additional Information

Starting with NSX 6.2.3, the default VXLAN port is 4789, the standard port assigned by IANA. Before NSX 6.2.3, the default VXLAN UDP port number was 8472.

VMware vSphere 6.0 supports VIB downloads over port 443 (instead of port 80). This port is opened and closed dynamically. The intermediate devices between the ESXi hosts and vCenter Server must allow traffic using this port.
VXLAN port 8472 is reserved or restricted for VMware use, any virtual machine cannot use this port for other purpose or for any other application.

For more information regarding port requirements with other VMware Products, see TCP and UDP Ports required to access VMware vCenter Server, VMware ESXi and ESX hosts, and other network components (1012382).

For more information on NSX ports, see the Ports Required for NSX Communication section in the NSX Installation and Upgrade Guide.
