PowerCli – Deploy Linked Clone with Static IP

by Jon

I’m not sure why it’s been so hard to find a snippet online that gives me the ability to create a linked clone while selecting a static IP address, but it was. I ended up writing a quick function to help.

It should be pretty self explanatory.. just edit the variables in the parameter section and call the function.

Cheers!
