Does Phone NTP Server reference change my licensed files, (CUCM)?

[Juan Gerardo Hernandez]

Hi all,

Good day.

I just wanted to know of on my CUCM Admin web page, on PHONE NTP REFERENCE, if adding or deleting NTP's does make my CUCM to re-host my active licensed files.

Because I changed the NTP server on the CLI call manager, (delete it and added one). And now all my licenses are invalid

I have a few more questions.

Which are the differences between of the Phone NTP Reference Server and NTP reference servers (CLI)?

Which one I do not must change?

If mi licenses say "Invalid", what is the worst case scenario could happen with my current configurations of IP Phones/GW/GK/Trunks/CSS?

Thanks in advice.

John

I assume you are using a UCS server,,,

The license MAC is generated by hashing the following user-configured parameters:

◊ Time zone

◊ NTP server 1 (or ?none?)

◊ NIC speed (or ?auto?)

◊ Hostname

◊ IP Address (or ?dhcp?)

◊ IP Mask (or ?dhcp?)

◊ Gateway Address (or ?dhcp?)

◊ Primary DNS (or ?dhcp?)

◊ SMTP server (or ?none?)

◊ Certificate Information (Organization, Unit, Location, State, Country)

When you change any of the parameters that create the license MAC,  the license that you obtained with it becomes invalid. You must request a  rehosting of the license to obtain a valid license. The old license  continues to work for a 30-day grace period.

#

To rehost your licenses, you must open a case with the licensing team. Contact the licensing team at licensing@cisco.com.

#

During  the grace period, you can change the settings back to the licensed  values to make your original license valid again. If you need more than  30 days of grace period, change your settings back to the licensed  values, then change them back to the new values that you want to use.  You will get another 30- day grace period.

The phone NTP reference does not affect the license.

Yes, but he originally asked if changing the phone NTP reference changed the license file

Hi, is this also true for v9 with new generate license request method?

[Ayodeji Okanlawon]

No, the licensing for v9 uses ELM, hence there is no license MAC..Its completely different
