What command is used to enable the DNS server on a Cisco device?
This is the same command I ran before on a different Cisco device, but now the line comes out as unknown.
What should I do?
After doing some digging (and probably some guesswork), I found a possible explanation. The CLI command for the Cisco device I'm working on is (the line you see comes from another Cisco system running in another mode): service no ip domain-name-server. That is, the CLI command to enable the DNS server is service, and no is an optional parameter to the command. The documentation specifically refers to this as a command override.
While none of the other examples of the service command include this type of override, I'm not sure what the difference between that behavior and what I observed on my Cisco device. Maybe the CLI behavior will change or the option will become unnecessary when IPv6 comes to Cisco products.
