Using the Commands

How to Enter CLI Commands

Capitalization in commands and arguments

Commands are valid in lowercase, uppercase, or mixed case, but arguments are case-sensitive unless specified otherwise.

Editing in the CLI

The BACK SPACE key deletes the most recently entered character of the current command string. No other editing function is available during command entry.

The CLI does not retain a command history. You cannot retrieve previously entered commands.

The Space character as command delimiter

The CLI uses one Space character (ASCII 0x20) as the delimiter between commands and arguments; extra Space characters are ignored.

Quotation marks and the reverse slant

Use quotation marks (ASCII 0x22) and the reverse slant (\: decimal code 92) as follows:

•For both input and output, enclose in quotation marks any string value that begins or ends with spaces or contain commas or semicolons.

•Do not use traditional escape sequences (the reverse slant followed by a lowercase alphabetic character or by one or more numeric characters) preceding special characters within strings. The CLI does not recognize such escape sequences, and the resulting error causes the entire keyword and value pair to be ignored.

•If an argument value contains a quotation mark or reverse slant, it must be preceded by a reverse slant only as its escape character. For example, this command adds the user "John Doe" to the local database:

adduser \"John Doe"

•If an input string contains a quotation mark or reverse slant, enclose the string in quotation marks. For example, this command adds the user pdu\\device to the local database:

adduser "pdu\\device user"

•Optionally, you can use quotation marks to enclose any argument value.

Command Line Interface (CLI) User’s Guide

Command Line Interface specifications

The APC Command Line Interface (CLI) is a powerful tool offered by American Power Conversion (APC) for managing and configuring various APC devices, such as uninterruptible power supplies (UPS), power distribution units (PDUs), and cooling solutions. The CLI enables users to perform a wide range of functions, from monitoring device status to configuring settings and automating tasks, all through a command-line environment. This capability is particularly beneficial for system administrators and IT professionals who prefer scripting and automation to manage their energy infrastructure.

One of the main features of the APC CLI is its comprehensive control over device parameters. Users can retrieve important information like battery status, load levels, and input/output voltages directly through command-line queries. This instant access to critical data allows for more efficient troubleshooting and monitoring of system health. Additionally, the CLI supports historical data retrieval, giving users the ability to analyze performance trends over time.

Another significant technology underlying the APC CLI is SNMP (Simple Network Management Protocol). SNMP allows for seamless integration with network management systems, enabling users to manage APC devices alongside other networked hardware. The CLI’s compatibility with SNMP makes it easier to incorporate APC devices into larger monitoring frameworks, enhancing overall system management.

Security is a vital characteristic of the APC CLI, as it often involves sensitive operational data. The interface typically supports user authentication, ensuring that only authorized personnel can access critical functions. Features like secure SSH (Secure Shell) connections provide encrypted communication channels for remote device management, protecting against unauthorized access and data breaches.

The APC CLI also provides batch processing capabilities, allowing users to execute multiple commands in a single session. This feature is particularly useful for large-scale operations where numerous devices need to be configured or monitored simultaneously. Automated scripts can be created to execute routine tasks, significantly reducing administrative overhead and minimizing the risk of human error.

In conclusion, the APC Command Line Interface stands out as an essential tool for efficient energy management. Its rich feature set, powered by modern technologies like SNMP and strong security protocols, enables comprehensive control over APC devices. With automation capabilities and real-time data access, the APC CLI is indispensable for IT professionals aiming to optimize their power management strategies and ensure system reliability.
