Using the Command-Line Interface

The VPN 3002 Hardware Client command-line interface (CLI) is a menu- and command-line-based configuration, administration, and monitoring system built into the VPN 3002. You use it via the system console or a Telnet (or Telnet over SSL) session.

You can use the command-line interface to completely manage the system. You can access and configure the same parameters as the HTML-based VPN 3002 Hardware Client Manager.

This chapter describes general features of the command-line interface and how to access and use it. It does not describe the individual menu items and parameter entries. For information on specific parameters and options, see the corresponding section of the Manager in this manual. For example, to understand Ethernet interface configuration parameters and choices, see Configuration Interfaces Private/Public in Chapter 3, “Interfaces”.

Accessing the Command-line Interface

You can access the command-line interface in two ways: via the system console or a Telnet (or Telnet over SSL) client.

Console Access

To use the console:

1.Connect a PC to the VPN 3002 via an RJ-45 serial cable (which Cisco supplies with the system) between the console port on the VPN 3002 and the COM1 or serial port on the PC. For more information, see the VPN 3002 Hardware Client Getting Started guide.

2.Start a terminal emulator (e.g., HyperTerminal) on the PC. Configure a connection to COM1 with port settings of:

9600 bits per second.

8 data bits. No parity.

1 stop bit.

Set the emulator for VT100 emulation, or let it auto-detect the emulation type.
