I recently needed to change the IP address of my PSC. Unfortunately it was already inaccessible so I was unable to do it via the standard GUI methods. I SSH’d into the box and had a look but it pretty immediately becomes apparent you can’t just update things the way you would a normal linux box. Enter vami_config_net. I believe this utility is available on any of the VMWare appliances that utilize VAMI/photon but I could be wrong. As you may notice int he article it refers to this being for the vCetner Support Assistant, but it worked just the same for me on my external PSC.
