changing DNS of CUC 9.x

[ccg-collab1]

Hi All,

Good Day. We would like to ask if we need to rehost the license of CUC after changing the DNS of CUC Application version 9.X? Am i correct that it is just the same process as the CUCM wherein we need to remove first the product instance on the PLM before changing the DNS on CUCM/CUC?

Appreciate your inputs,

Thank you,

Kier

I believe your CUC is added in Enterprise License Manager. There is no  need to rehost License for CUCM after changign DNS. DNS Change will not impact License.

With Previous Version 8.X it was the case.

Thanks

Hi Haris,

Thanks for your response. Yes, you are correct. CUC license is added to the ELM. How about for the UCCX 10.6? Is it require to rehost the license?

Thanks,

With UCCX it will Impact the License MAC

Refer below

The Unified CCX licenses are based on a string called the license MAC, which is different from the physical MAC address of a system. License MAC is dependent on the system parameters. A modification to any of the parameters can change license MAC, thereby invalidating current License files. The following are the parameters on which the validity of a license MAC depends:

• Time zone
• NTP server 1 (or none)
• NIC speed (or auto)
• Hostname
• IP Address
• IP Mask
• Gateway Address
• Primary DNS
• SMTP server
• Certificate Information (Organization, Unit, Location, State, Country)

Note

The Unified CCX Warm Standby license and all other licenses are node-locked to the License MAC address of the first node (typically the Database Publisher node) of a Unified CCX cluster. When a second node is added, the verification of a valid add-on Warm Standby license on the first node is performed. After the cluster is set up, the licenses are valid on both the nodes in a cluster.
