Appendix C: Undocumented Cisco Commands

This long list of undocumented Cisco commands has been gathered by hundreds of people using a variety of Cisco devices. Many of these commands have been taken from Lars Fenneberg's web site at http://www. elemental .net/~lf/undoc/ . If you know of other undocumented commands, please share them with other people by submitting the command and description to Lars at lf@elemental.net .

Depending on what version of IOS or CatOS you are using, some of these commands may already be documented, not used anymore, or not supported by that version of the system. Use these commands at your own risk.
