How to Change DNS server on CUCM 6

Hi,

How can we change the DNS server on CUCM 6?

The existing DNS is going to retire soon.

Thanks

You can change this using CLI

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
