DGS-1520 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide NOTICE: A notice indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. CAUTION: A caution indicates a potential for property damage, personal injury, or death. ATTENTION: Une précaution indique un risque de dommage matériel, de blessure corporelle ou de mort. Connecting to the Console Port The Console port is used to connect to the CLI of the Switch. Connect the DB9 connector of the console cable (included in the packaging) to the Serial (COM) port of the computer. Connect the RJ45 connector of the console cable to the Console port on the Switch. To access the CLI through the Console port, Terminal Emulation Software must be used like PuTTY or Tera Term. The Switch uses a connection of 115200 bits per second with no flow control enabled. After the boot sequence completed, the CLI login screen is displayed. Command Descriptions The information pertaining to each command in this reference guide is presented using a number of template fields. The fields are: • Description - This is a short and concise statement describing the functionality of the command. • Syntax - The precise form to use when entering and issuing the command. • Parameters - A table where each row describes the optional or required parameters, and their use, that can be issued with the command. • Default - If the command sets a configuration value or administrative state of the Switch then any default settings (i.e. without issuing the command) of the configuration is shown here. • Command Mode - The mode in which the command can be issued. These modes are described in the section titled "Command Modes" below. • Command Default Level - The user privilege level in which the command can be issued. • Usage Guideline - If necessary, a detailed description of the command and its various utilization scenarios is given here. • Example(s) - Each command is accompanied by a practical example of the command being issued in a suitable scenario. Command Modes There are several command modes available in the command-line interface (CLI). The set of commands available to the user depends on both the mode the user is currently in and their privilege level. For each case, the user can see all the commands that are available in a particular command mode by entering a question mark (?) at the system prompt. The command-line interface has three pre-defined privilege levels: • Basic User - Privilege Level 1. This user account level has the lowest priority of the user accounts. The purpose of this type of user account level is for basic system checking. This user account level can only show information not security-related. • Operator - Privilege Level 12. This user account level is used to grant system configuration rights for users who need to change or monitor system configuration, except for security related information such as user accounts and SNMP account settings, etc. • Administrator - Privilege Level 15. This administrator user account level can monitor all system information and change any of the system configuration settings expressed in this configuration guide. 2
