<div>I would be curious as to what the clock strata on the primary server was at, prior to the reboot and the type of reference server?</div>
<div><br>
</div>
<div>If you have root access and are familiar with the CET tool, you <i>can</i> change the server's MAC. The official (and supported) way to do it is through a TAC case; sometimes faster than GLO.</div>

<p>The server's licensing MAC address is a hashed hexadecimal value based on several key settings in the operating system. Any changes to the following list of OS settings will cause the License MAC on the server to change, thereby invalidating the provisioned
license file (which is bound to the server's licensing MAC address). Did anything change on the server, that would effect the licensing MAC, prior to the reboot? As you mentioned, re-hosting the license through GLO (or reverting the change) are the only remedial
courses of action.</p>

<p>Hi,</p>
<p><br>
</p>
<p>Has anyone run into licensing not working due to invalid MAC address after server reboot? Ive had this occur twice over the last 12 months. Single CCX server on VMWare using Cisco .ova template. I had to get the licensing rehosted to resolve the issue.
I didn't see anything in caveats for the release.<br>
