Enabling load-balancing for the non-management VxRail networks requires peering the pair of ports on each VxRail node with a pair of ports on the ToR switches.
If you are enabling LAG across a pair of switches, and you have matching open ports on both switches, the best practice is to plug the cables into equivalent port numbers on both switches. Create a table to map each VxRail node port to a corresponding switch port. Identify which ports on each VxRail to be enabled for LAG.
For example, if you want to deploy a VxRail cluster with four nodes, and reserve and use two ports on the NDC or OCP and two ports on a PCIe adapter card for the VxRail cluster, and use the first eight ports on a pair of ToR switches for connecting the cables, you could use the resulting table to identify the switch ports to be configured for LAG.
Assuming that you are using the second port on the NDC or OCP and PCIe adapter card for the non-management VxRail networks, you can identify the switch port pairs, as shown in the columns shaded green, to be configured for LAG. Create a table mapping the VxRail ports to the switch ports as part of the planning and design phase.
