Enabling DNS on production UCCX servers

[Jason Ward]

Hi all,

We have a client that has a UCCX install that was not configured to use DNS and we'd like to rectify that. Is there a documented procedure for enabling DNS after a server has been in production for a while? I see commands for setting a primary and secondary address in the CLI, but will this actually enable DNS as well? I imagine the license MAC will also change, so I'll need to get Cisco licensing involved.

Any advice would be very much appreciated

Thanks in advance,

Jason

Hi Jason,

DNS is mandatory for UCCX 8.x installation .How u  have installed it earlier?

The license MAC would change.It depends on parmeters .

Modifying any of these parameters can change License MAC thereby invalidating current License files.

Here 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)

I imagine when the installer asks if you want to use DNS, you select 'No'

Hi Jason,

You need to contact Cisco TAC to get the license key "re-hosted" since license MAC would change.

You need to use the commands  to configure DNS

set network dns primary ip-address

set network dns secondary ip-address

Hope this helps.
