How to Add a Physical Nic to a Virtual Switch

With my brand new VMware ESXi Installation, it takes some time to configure everything to your liking and to best practices.  ESXi 6.5 is not shy about warning you when you do not have redundancy or something configured as it should.

With my setup I have two 1Gbe NICs but ESXi only configured one NIC as the second was not active.  Now that it is cabled and active, lets add it to the Virtual Switch.

At the main ESXi home page, click on Networking and verify that each NIC you wish to use shows as Enabled and has a Link Speed correct for the Network Adapter

For my installation the only two NICs we worry about are the first two, as vmnic2 corresponds to a 10Gbe Mellanox Card that has yet to be configured.

If we click on vSwitch0 we notice that VMWare has a warning!

If we click Actions we can Choose “Add Uplink”

We can see that VMware has added vmnic1.  Now wasn’t that simple!  No digging for the correct setting, just nice and easy.

Once we save and refresh the view, we see the Warning is gone and that we now have the two adapters configured for the Switch.

If we look at the Monitor tab under the VMNetwork we can see in the Events that the warning has cleared and why.
