ADDING DNS SERVER TO CUCM

[ugwuugochukwukizito]

Hello,

Please I have tried adding a dns server to CUCM 11.5 with the following commands:

set network dns primary x.x.x.x

set network dns secondary x.x.x.x

This was successful but when I log on to the CUCM, it shows me DNS UNREACHABLE. I have checked everything and I can't seem to figure out what the problem could be.

Kindly assist.

Hello Marce1000, 

Thanks for your previous response.

Attached are screenshots from my clients CUCM publisher, OS administration and CLI. 

Could the cause of DNS UNREACHABLE  be that the pub has no domain yet as can be seen from the OS admin screenshot, If yes I tried adding a domain but the message I get from the CLI isn't clear enough. 

Will adding a domain affect the CUCM in any way?

Regards
