The physical mac address is most commonly used to identify an NX client as a registered computer in a node locked installation, and the CID is most commonly used to identify a computer as a registered NX SPLM License Server. Although that sounds pretty straight forward, their roles are totally reversed in Solid Edge installations that do not incorporate the use of a hardware dongle. In Solid Edge installations, the mac address usually identifies the computer as a registered Solid Edge SPLM License Server, and the CID usually identifies the computer as a Solid Edge node locked client. In any case, you may be asked to provide one or the other when the time arrives to replace an obsolete or failed computer, so I thought I'd tell you where to get them both.
1. You can get the physical mac address in the following manner:
In a Win 7 or Win 8 CMD (DOS) window type the command "ipconfig /all” and then enter. What you are looking for is the Physical Address of your Ethernet or Wireless LAN adapter. It is a (12) digit hexadecimal number that is segmented into groups of six two digit values that are separated by dashes.
2. You can get the CID by downloading the "getcid.exe" executable from the following GTAC Download Server URL (You will need a WebKey account and password):
You can run the program from your download folder by double clicking on it in Windows Explorer. The CID is an encrypted version of the mac address which is also a (12) digit hexadecimal value in a single string. If you have multiple network adapters installed, you may see more than one CID. If you are unsure about which one to pick, use the first one on the list.
As always, I hope that this helps in some small way.
Thanks for reading...
