How to change dns on switch?

To change the DNS settings on a network switch, you'll typically access the switch's management interface via a web browser or console connection. Once logged in, navigate to the DHCP or network settings section, where you can specify the DNS server addresses you want to use. After entering the new DNS information, save the changes and restart the switch if necessary for them to take effect. Be sure to check the documentation for your specific switch model as the steps may vary slightly.
