An interesting sub-thread to this could be: Have you ever unintentionally crashed a device by running a perfectly innocuous command? 1. Crashed a 6500/Sup2 by typing "show ip dhcp binding". 2. "clear interface XXX" on a Nexus 7K triggered a cascading/undocument Sev1 bug that caused two linecards to crash and reload, and take down about two dozen buildings on campus at the .edu where I used to work. 3. For those that ever had the misfortune of using early versions of the "bcc" command shell* on Bay Networks routers, which was intended to make the CLI make look and feel more like a Cisco router, you have my condolences. One would reasonably expect "delete ?" to respond with a list of valid arguments for that command. Instead, it deleted, well... everything, and prompted an on-site restore/reboot.
BCC originally stood for "Bay Command Console", but we joked that it really stood for "Blatant Cisco Clone".
