3 The Command Line Interface
This chapter describes how to access and use the HL950 Command Line Interface.
3.1 Access the Command Line Interface (CLI)
You can access the CLI locally or remotely as shown in the figure below:
Figure 4
Methods for Access to the HL950 CLI
3.1.1 Access the CLI via Console Port
This is a basic method for commissioning a new HL950.
1. Connect a PC to the HL950 CONSOLE port by means of a standard RS-232 cable.
2. Restart the PC (if required by your operating system).
3. Open a terminal window or start at terminal session on the PC. For example, if you use the
Hyper Terminal emulator available under the Windows operating system, connect as follows:
! In the Connection Description dialog box, enter a name and select an icon for the
connection.
! In the Connect to dialog box, select COM1 (or COM2) depending on which serial port
you are using.
! In the COM1 (or COM2) Properties dialog box, enter the following port settings:
Baud rate: 9600, Data: 8 bit, Parity: none, Stop: 1 bit, Flow Control: none.
! The HL950 displays the command line. Enter the user name and password.
3.1.2 Access the CLI via Ethernet Local LAN
Use this method for in-service OAM. In this case, the HL950 Ethernet ports already have been
configured for LAN access so that the HL950 management system can be accessed from the IP
network using Telnet.
NOTE!
The HL950 Telnet Service must be running before you can connect via Telnet. If Telnet is not
running, you must connect to the HL950 using the CONSOLE port and use the start
service telnet command to start the service. (For security reasons the Telnet service is
disabled by default).

1. Connect the LAN to the Ethernet port on the HL950 that has been configured for LAN access.
2. For example, if you use the Telnet session available under Windows for LAN and remote
access, configure it as follows:
! In the Windows start menu select Run….
! In the Run dialog box enter telnet.
! Connect to the IP address for the HL950.
! The HL950 displays the command line. Enter the user name and password.
! If your Telnet application is GUI-based, you may be able to configure your Telnet
terminal preferences to allow VT-100 compatibility so you have scrolling and cursor
arrow navigation. If your Telnet application is CLI-based, you should have scrolling and
cursor arrow navigation. Access your Telnet application’s online help (usually by typing
‘help’ or pressing ‘?’), or refer to your Telnet client documentation for more information.
3.1.3 Access the CLI from a Network Management Center
In this case, the HL950 is configured as a remote terminal to enable its management system to be
accessed remotely for commissioning purposes:
1. Use Telnet to access the HL950 CLI from a Network Management workstation. For
information on using Telnet, see “Access the CLI from a Local LAN” above.
2. Use FTP, TFTP or SFTP upload and download files and for general OAM.
3.1.4 User Accounts and Access Rights
The HL950 CLI supports two different user accounts;
! ROOT – with factory default user name root, and default password snowbomb
! USER – with factory default user name user, and default password firebird
Each account corresponds to three authority classes with different access rights as described in the
table below.
Authority Class
User Account ADMIN USER EVERYONE
ROOT Full read/write/execute Full read/write/execute Full read/write/execute
USER - Read only Full read/write/execute
Table 1 - User Accounts and Authority Classes for the HL950 CLI
Each command in the CLI is assigned to one of the authority classes.
The ROOT account has full READ, WRITE, and EXECUTE access to all commands.
The USER account has READ ONLY access to commands with authority class set to USER and full
READ, WRITE, and EXECUTE access to commands with authority class set to EVERYONE.
NOTE!
It is recommended that the administrator change the default passwords to prevent
unauthorized access. For more information on default user names and passwords, see section
8.1 “Reset System Password”.

3.2 Command Structure
The HL950 Command Line Interface allows HL950 administrators to set up, configure and manage
HL950 devices. It also allows HL950 non-privileged users to view the current status of the HL950 but
not to make changes to the system.
For a detailed description of all CLI commands, including authority, available prefixes and
parameters, see chapter 6 “CLI Commands”.
3.2.1 Main Commands
The Main Commands are primarily related to the HL950 operating system and are as follows:
Main commands:
CAT CD CHKDSK CLS CONFIG CP EXIT
FLASHLED FLUSH FORMAT FTP LINE LOGOFF LS
LSR MKDIR MV PASSWORD PING PWD QKEY
RELOAD RM RMDIR SAVE TAR TFTP UPGRADE
WHOAMI WHOISON XCP XRM
Figure 5
Main Commands for the HL950 CLI
3.2.2 Commands for Functions and Services
The commands for functions and services are divided into three parts; Prefixes, Subgroups and
Elements. The command convention is a combination of “prefix-subgroup-element” followed by a
number of parameters and their values.
3.2.2.1 Command Prefixes
There are eight command prefixes as follows:
! SET –sets configuration values.
! SHOW – displays configuration values.
! ADD – adds objects.
! DEL – deletes objects and their values.
! START – starts the object designated by the command’s subgroup-element modifiers. (Once
you start services and interfaces, they will start automatically upon system restart).
! STOP – halts the object designated by the command’s subgroup-element modifiers.
! HELP – displays available commands. When used alone, you see the help system for the
HL950. When you use HELP as a prefix to a command, you see the help for that command.
