Deployment Guide for Cisco Guest Access Using the Cisco Wireless LAN Controller, Release 4.1
OL-13691-01
Configuring Guest Access on the Cisco Wireless LAN Controller
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
This document includes various scenarios in which the Cisco Wireless LAN Controller can be used to
deploy a guest access solution over the corporate network.

Configuring Guest Access on the Cisco Wireless LAN Controller
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.
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:
critical elements are required:
•
A dedicated guest SSID/WLAN – Required within all wireless networks that require guest access.
•
Guest traffic segregation or path isolation – To restrict guest user traffic to distinct, independent
logical traffic paths within a shared physical network infrastructure.
logical traffic paths within a shared physical network infrastructure.
