Cisco Cisco 4404 Wireless LAN Controller Referências técnicas

Guest networks are network connections provided by an enterprise to enable their guests to gain access 
to the Internet, and the guests’ own enterprise without compromising the security of the host enterprise. 
The main technical requirements for a complete guest access solution are outlined below:

Complete integration into the enterprise network and its resources 

Logical separation (segmentation) of guest traffic from internal enterprise traffic

Secure VPN connections to guests’ own corporate networks

Authentication and login capabilities 

In this document, we have included various scenarios where the Cisco Wireless LAN Controller can be 
used to deploy a guest access solution over the corporate network.

An existing enterprise wired and wireless network infrastructure can be used to implement a wireless 
guest network. No separate, overlay network is required to support guest access.

Therefore, the overall implementation and maintenance costs of a guest network are greatly reduced. 

To successfully implement a guest network on an existing wired or wireless network, the following 
critical elements are required:

A dedicated guest SSID/WLAN – Required implementation within all wireless networks in which 
guest access is needed.

AP

Wireless access point

BBSM

Cisco Building Broadband Service Manager 

Cisco WiSM

Cisco Wireless Services Module

Lightweight AP

An access point running LWAPP that makes the AP work 
with the WLCs

LWAPP

Lightweight Access Point Protocol—IETF draft protocol 
used in the Cisco Centralized WLAN Architecture 
implementations. LWAPP defines both control and data 
encapsulation formats used in the Cisco Centralized 
WLAN Architecture

WCS

Cisco Wireless Control System—Management software 
that manages WLC devices and adds advanced 
management like location-based services

WLC

Cisco Wireless LAN controller—Cisco devices that 
centrally manage lightweight access points and WLAN 
data traffic
