Today I had a network issue in my lab, I still don’t have a clue what the issue was but I did discover something useful. I had 3 different VMkernel’s setup and I wanted to make sure each of the three had network connection to a specific destination address. After going through the esxcli command I bumped in to the following command which I found very helpful:
esxcli network diag ping -I vmk0 -H 10.27.51.132
In this case I use VMkernel Interface “vmk0” to ping to the address “10.27.51.132”. If I want to use a different VMkernel Interface I just specify it, so swap “vmk0” with “vmk1” for instance. Useful right?!
