Are you looking for the VMkernels specifically? Or do you need Guest VM IP's as well?
If you are just looking to list out the VMKernel ports, you can simply turn on SSH-- In vSphere client -> security profile -> properties -> SSH -> turn on.
SSH into the host using a program of choice (if unfamiliar google PuTTY).. Host IP and log in with root/local password that you've set.
Run this command :
esxcli network ip interface ipv4 get
Let me know if this helps or if that command doesn't run.
