D-Link NetDefend SOHO DFL-160, User Manual

Page: 107 / 130

Appendix A. CLI Reference
This section summarizes in alphabetical order the command set that can be entered through a
console connected to the RS232 console port on the DFL-160.
Details of how to connect up a console device to the console COM port on the DFL-160 can be
found in Section 2.4, “Console Port Connection”. Once the connection is made and NetDefendOS
has started up, pressing the Enter key on the console should get a CLI prompt response on the
console:
DFL-160:/>
It is advisable to use the Boot Menu to place a password on access through the console port to
prevent unauthorized access. How to do this is described in Chapter 8, The Console Boot Menu.
