Change ISE DNS IP

fdharmawan — Wed, 08 May 2024 03:46:47 GMT

Hi Guys,

Is there any procedure on how to change ISE IP address? We just migrated the DNS server and need to update the settings on the ISE.

What I know so far is that I suppose to change it via CLI. Our current setting is "ip name-server 192.168.0.10 192.168.0.11". In order to update it, I think I need to issue the "ip name-server 192.168.0.100 192.168.0.200" command. There are some questions that I do not get the answer to so far.
1. Should I issue the "no ip name-server 192.168.0.10 192.168.0.11" command to remove the old setting?
2. Should I restart the server or service of the ISE? If so, what is the procedure

Thank you.

If this is only DNS changing on ISE check this thread :

Changing the 'ip name-server' configuration will require a restart of ISE services on the node.

I would suggest using the 'reset-config' CLI command to make all necessary changes with a single restart of the ISE services. Otherwise, you will be prompted to restart the services with each change (no ip name-server xxx = restart #1; ip name-server xxx = restart #2, etc).

The reset-config command only seems to be valid at the console and for nodes that are in standalone mode. Is there any other way to change DNS servers in a distributed deployment without 2 service restarts?

No, these are the options
