Enhanced Editing
The router supports enhanced editing features that allow you to modify lengthy commands.
You can turn off the enhanced editing features by typing terminal no editing at either the User EXEC or any of the Privileged EXEC prompts.
You can turn on terminal editing by typing terminal editing.
If the router mistakes a mistyped command for a host name, it will, by default, attempt to lookup the host name.
If you would like to prevent the router from doing this, type no ip domain-lookup from the global configuration prompt.
