I don’t see any error on the image you shared. That’s a warning which inform you about the effect of dns change as the license mac will be changed if you change the dns. With new smart licensing it’s not a matter as you can reregister the device.

Btw what version of cucm you use?

You haven’t answered my question, what version is your cucm ?

you can change the dns

if I remember correctly the dns will not require a server restart and only the network restart will be triggered and which will be back in a mins or less

you can see the dns setting using “show network eth0”
