Cisco Wireless LAN Solution Overview
Cisco Wireless LAN Solution Overview
The Cisco Wireless LAN Solution is designed to provide 802.11 wireless networking solutions for
enterprises and service providers. The Cisco Wireless LAN Solution simplifies deploying and managing
large-scale wireless LANs and enables a unique best-in-class security infrastructure. The operating
system manages all data client, communications, and system administration functions, performs Radio
Resource Management (RRM) functions, manages system-wide mobility policies using the operating
system Security solution, and coordinates all security functions using the operating system security
framework.
The Cisco Wireless LAN Solution consists of Cisco Wireless LAN Controllers and their associated
lightweight access points controlled by the operating system, all concurrently managed by any or all of
the operating system user interfaces:
• An HTTP and/or HTTPS full-featured Web User Interface hosted by Cisco Wireless LAN
Controllers can be used to configure and monitor individual controllers. See the “Web User
Interface and the CLI” section on page 1-25.
• A full-featured command-line interface (CLI) can be used to configure and monitor individual Cisco
Wireless LAN Controllers. See the “Web User Interface and the CLI” section on page 1-25.
• The Cisco Wireless Control System (WCS), which you use to configure and monitor one or more
Cisco Wireless LAN Controllers and associated access points. WCS has tools to facilitate
large-system monitoring and control. WCS runs on Windows 2000, Windows 2003, and Red Hat
Enterprise Linux ES servers.
• An industry-standard SNMP V1, V2c, and V3 interface can be used with any SNMP-compliant
third-party network management system.
The Cisco Wireless LAN Solution supports client data services, client monitoring and control, and all
rogue access point detection, monitoring, and containment functions. The Cisco Wireless LAN Solution
uses lightweight access points, Cisco Wireless LAN Controllers, and the optional Cisco WCS to provide
wireless services to enterprises and service providers.
Note This document refers to Cisco Wireless LAN Controllers throughout. Unless specifically called out, the
descriptions herein apply to all Cisco Wireless LAN Controllers, including but not limited to Cisco 2000
Series Wireless LAN Controllers, Cisco 4100 Series Wireless LAN Controllers, Cisco 4400 Series
Wireless LAN Controllers, and the controllers on the Wireless Services Module (WiSM).
Figure 1-1 shows the Cisco Wireless LAN Solution components, which can be simultaneously deployed
across multiple floors and buildings.
