What should have been default on Cisco devices
Some things on Cisco switches and routers never should have been on by default. Other things should have been
turned on or set differently. This is not how I want them to be configured in the end (I like CDP for example),
just how I think they should have been configured from the factory.
(not all commands are supported on all switches/routers. Just ignore error messages from those settings)
