Explanation:
Uplink profiles within NSX-T shows that you can only use Load balance Source and Load balance Source MAC, failover order doesnt provide any load balancing or high throughput https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.1/installation/GUID-50FDFDFB-F660-4269-9503-39AE2BBA95B4.html
https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/installation/GUID-50FDFDFB-F660-4269-9503-39AE2BBA95B4.html Failover Order: Select an active uplink is specified along with an optional list of standby uplinks. If the active uplink fails, the next uplink in the standby list replaces the active uplink. No actual load balancing is performed with this option. Load Balance Source: Select a list of active uplinks. When you configure a transport node, you can pin each interface of the transport node to one active uplink. This configuration allows use of several active uplinks at the same time. Load Balance Source MAC Address: Select an uplink based on a hash of the source Ethernet.
