VMware Distributed Switch – identify which Network Card Traffic for a VM is going over

If you have a distributed switch you can’t easily identify what physical network card the traffic for a VM is going out through. In order to find out you need to first of SSH to the host where the VM sits.

In my example we are going to use a test VM with the name of Data. Run the command below.

net-stats -l | grep Data

It will return a single line of data. We are interested in the number to the left. Make a note of this number and then type :



get /net/portsets/DvsPortset-1/ports/number returned from above/teamUplink

So in our example it would be

get /net/portsets/DvsPortset-1/ports/50331690/teamUplink

It will then tell you which physical nic it is using.
