How to Change DNS server on CUCM 6

[Kumar Vishal]

Hi,

How can we change the DNS server on CUCM 6?

The existing DNS is going to retire soon.

Thanks

Kumar

Hi

You can change this using CLI

Let me know if that helps you...

Thanks!!!

Thanks a lot.

1 final thing - do we need to restart CUCM server or CUCM service after the changes?

It says in the document - "Make sure that the Cisco Unified Communications Manager is restarted after this configuration."

Restart the server.

A DNS entry change would restart the network service on the server automatically. AFAIK, a server restart is not needed if ONLY the DNS server address is being changed.

You would want to keep in mind http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCth09430

If the Domain Name is being changed

- keep in mind http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtg04086

- Every server in the cluster has to be rebooted, for the hosts files to match up and db replication to work fine
