Command Line Interface (CLI)
•
Image File - The Access Point software executed from RAM. To update an Access Point you typically download a
new Image File. This file is often referred to as the “AP Image”.
•
Parameter - A fundamental network value that can be displayed and may be changeable. For example, the Access
Point must have a unique IP Address and the Wireless interface must be assigned an SSID. Change parameters
with the CLI
set
Command, and view them with the CLI
show
Command.
•
Table - Tables hold parameters for several related items. For example, you can add several potential managers to
the SNMP Table. All items for a given Table can be displayed with a
show <Table>
CLI Command.
• TFTP - Refers to the TFTP Server, used for file transfers.

Command Line Interface (CLI) Variations
Administrators use the CLI to control Access Point operation and monitor network statistics. The AP supports two
types of CLI: the Bootloader CLI and the normal CLI. The Bootloader CLI provides a limited command set, and is used
when the current AP Image is bad or missing. The Bootloader CLI allows you to assign an IP Address and download a
new image. Once the image is downloaded and running, the Access Point uses the normal CLI. This guide covers the
normal CLI unless otherwise specified.
