Hi,
My customer has disabled one of their DNS servers which is currently used as the secondary DNS on CUCM.
They are not replacing this server and will run with just a single DNS server (I do not think this is a good idea but they seem set on doing it).
Is there any way to remove the secondary DNS entry from UCM? - there does not seem to a CLI option to do this.
I have tried setting the secondary to 0.0.0.0 and to the IP address of the primary DNS but these options both fail as shown below.
admin:set network dns secondary 0.0.0.0
Executed command unsuccessfully
0.0.0.0 is an invalid IP address.
admin:set network dns secondary 10.1.1.100
Executed command unsuccessfully
10.1.1.100 is already a configured DNS IP address.
Does anyone know any way of clearing the secondary DNS server entry?
Thanks

Hi James,
Command is: delete dns
Example:
admin:delete dns 10.104.149.89
*** W A R N I N G ***
This will cause the system to temporarily lose network connectivity
Continue (y/n)?y
trying to restart network...

You can use the above command for primary or secondary DNS.
HTH.
