Appendix A Using the Command-Line Interface

Accessing the CLI

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

Console access

To access the CLI via console:

Step 1 Connect a PC to the VPN Concentrator via a straight-through RS-232 serial cable (which Cisco supplies

with the system) between the Console port on the VPN Concentrator and the COM1 or serial port on the

PC. For more information, see the VPN Concentrator Getting Started manual.

Step 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.

• Hardware flow control.

Step 3 Set the emulator for VT100 emulation, or let it auto-detect the emulation type.

Step 4 Press Enter on the PC keyboard until you see the login prompt. (You might see a password prompt and

error messages as you press Enter; ignore them and stop at the login prompt.)

Telnet or Telnet/SSL Access

To access the CLI via a Telnet or Telnet/SSL client:

Step 1 Enable the Telnet or Telnet/SSL server on the VPN Concentrator. (They are both enabled by default.)

See the Configuration | System | Management Protocols | Telnet screen on the VPN Concentrator

Manager.

Step 2 Start the Telnet or Telnet/SSL client, and connect to the remote system using these parameters:

• Host Name or Session Name = The IP address on the VPN Concentrator Ethernet 1 (Private)

interface; e.g., 10.10.147.2

• Port = Telnet (The default Telnet port is 23; the default Telnet/SSL port is 992.)

• Terminal Type = VT100 or ANSI

• Telnet/SSL only: If the client offers it, enable both SSL and SSL Only.

Step 3 The VPN Concentrator displays a login prompt:
