Modify License MAC Cisco used to bind license file to physical MAC address. address. Now, it moves to "License MAC", which is a hash value of multiple system parameters such as NIC speed, NTP, DNS, hostname, etc. To view the license MAC, you need to install the system first (CUCM, UCCX, CUPS, CUPS, etc.). Then use the "show status" command.

Since you can use whatever License MAC you like, you may:

to FinalString="abcdef123456" In newer versions, you might have to change the /etc/selinux/config file so that selinux runs in permissive mode. Reminder: Don't be evil. ;) POSTED BY M I C H A E L L U O A T 6 : 1 5 P M

Anonymous September 25, 2011 at 7:45 PM Cisco has updated the Answer File Generator (http://www.cisco.com/web/cuc_afg/) to give you the license MAC based on your provided install values. You have to fill in the values EXACTLY as you would during the install, or else the license MAC will be different. But, it's another option besides having to wait til after installation to get the license MAC. Reply

Yes, we all know about the Answer File Generator. There's another reason to temper the License MAC, which I cannot explicitly state here. :) Reply

Anonymous November 18, 2011 at 12:34 AM I noticed that on CUCM 8.6.x Selinux is running in enforcement mode, so the LicenseMac.sh file will not be run after editing it. I had to change the /etc/selinux/config file so that selinux runs in permissive mode. After a reboot the MAC address was set correctly. Reply

Anonymous May 22, 2012 at 6:15 PM It works but I always get a database communication error and all the services are down after changing the License MAC. Anyone know what's wrong?

Teashaw February 26, 2013 at 8:14 PM It works on CUCM 8.6.2, I takes me some time to find the config file on /mnt/sysimage/partB directory. Thanks anyway, very helpful for my testing environment. Reply
