vmnic usage

[jamesbrown2123]

There are virtual machines in the port groups I created on the switch. There are 2 physical uplink connected to vSwitch. Do virtual machines actively use 2 uplink connected to vswitch?

To answer this question clearly, I need to know the load balancing option you used on vswitch. Which mode do you use?

I am using Route Based on Originating Virtual Port.

With the default setting "Route Based on Originating Virtual Port" the uplinks are assigned in a Round-Robin manner, as you power on the VMs. If an uplink failes, the VM will be mapped to another available vmnic.

If you are using Route Based on Originating Virtual Port, your virtual machines only use 1 uplink. If you're wondering which uplink virtual machines are using, do the following.

Connect to ESXi with SSH. Type "esxtop". Press "n" key.
