Configuring Guest Access on the Cisco Wireless LAN Controller
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:
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.

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:
