DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch CLI Reference Guide CAUTION: A caution indicates a potential for property damage, personal injury, or death. 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 commands functionality. • 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 five 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. • Advanced User - Privilege Level 3. This user account level is allowed to configure the terminal control setting. This user account can only show limited information that is not related to security. • Power User - Privilege 8. This user account level can execute fewer commands than operator, including configuration commands other than the operator level and administrator level commands. • 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. The command-line interface has a number of command modes. There are three basic command modes: • User EXEC Mode • Privileged EXEC Mode • Global Configuration Mode All other sub-configuration modes can be accessed via the Global Configuration Mode. When a user logs in to the switch, the privilege level of the user determines the command mode the user will enter after initially logging in. The user will either log into User EXEC Mode or the Privileged EXEC Mode. • Users with a basic user level will log into the switch in the User EXEC Mode. 2
