Switch Directly to Client Test

The purpose of this test is to see if a 10Gb/s switch with a 10Gb/s SFP will autonegotiate when plugged directly to a client.

Setup

Section titled “Setup”

I first plugged a Dell Precision 7730 with Intel I219-LM network card into Ethernet 1/1/8.

I later plugged in an ESXi instance with an Intel x710 to Ethernet 1/1/7.

SFP Used

Results

Section titled “Results”

I had to set the interface speed for it to pick up, but once the interface speed was set it worked.

On the client side the network showed Unidentified both before and after the change in the speed configuration.

After I brought the interface up I connect Ethernet 1/1/7 to the Intel x710 with ESXi hosting the card. I connected it to a RHEL 8 VM and confirmed ping worked between the 7730 and the ESXi instance.
