<div dir="ltr">The easiest way to view the license MAC, is to SSH to the server, and issue the show status command.<div><br></div><div>Also, <a href="http://cisco.com/go/license" target="_blank">http://cisco.com/go/license</a> enables you to rehost your own license files without opening a case.

If my primary DNS was 1.1.1.1, and I changed it to 2.2.2.2, I would have 30 days to rehost my licenses. On day 28, I set the primary DNS back to 1.1.1.1, then immediately back to 2.2.2.2, and the 30 days starts over.</div><div><br></div><div>Last, buy certainly not least, if you are changing DNS settings, it would be imperative for you to consider what might happen if you changed your DNS suffix. I cannot speak to your environment exactly, but suffice it to say, certificates are based on names, and names sometimes contain DNS suffixes. You might start a chain reaction of changes, and as such you should plan that piece out more carefully. If you're only changing DNS server addresses, then you can ignore this last paragraph.</div><div><br></div><div>Good luck.</div><div><br><div class="gmail_quote">On Mon Jan 26 2015 at 4:43:19 PM Gyrion, Larry <<a href="mailto:Larry.Gyrion@deancare.com" target="_blank">Larry.Gyrion@deancare.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">

<p class="MsoNormal">Looking for some guidance on updating the DNS entries on our CUCM cluster. A colleague went through the process, but upon entering the command received a warning stating that the change would invalidate our licenses. Has anybody come
across this before, and if so, what was the proper course of action to ensure license preservation?<u></u><u></u></p>
