I'm trying to inject extra information in option 12 of the DHCP requests the IVE/NC sends to an external DHCP server; specifically turning the client hostname into something like <user>@<hostname>. By default the IVE sends the client hostname as option 12. I can override it and define option 12 to be something else, but search as I have I can't find any variable that actually contains that hostname in the IVE. Is it just a pass-through option (inserted by the client host and not transformed by the NC client or IVE at all), or is there a variable I can use to get that info from?
Which hostname: the IVE or the physical client PC?
The client. Same hostname it provides to the DHCP server as part of the DHCP request.
