Re: Cisco commands are live too
The scenarios that can bite a long time after are those that can really be hard to track down as a result.
For example, the difference between live and stored configuration. Make changes to the live configuration and test to make sure that it works. Then forget to save the running configuration. Nothing bad happens until an unspecified period of time later and the system is restarted for whatever reason and it reverts back to the previous, stored configuration and things stop working.
