Management Interface Options

Management support for the 108 Mbps Wireless AP is available through four different interfaces:

Interface

Description

Web Browser Interface

This is the primary user interface for basic and advanced AP 
configuration support for a single AP. This guide presents all 
configuration tasks using the web browser interface.

NM Explorer

A built-in NM Portal web interface is available to manage multiple APs. 
For details on using NM Portal, see Chapter 9,  “Managing the Network.”

Command Line 
Interface (CLI)

The command line interface (CLI) for the 108 Mbps Wireless AP is 
accessible through a local 9-pin serial console port or over SSH. For more 
information on using the CLI to configure the AP, see Appendix A,  
“Using the Command Line Interface.”

Wireless LAN Network 
Management Software

The Wireless LAN Network Management Software user interface 
provides access to AP configuration functions and is designed to manage 
very large numbers of access points and networks. For more information, 
see the 

Wireless LAN Network Management Software Installation and 

User Guide
