This document contains links to documents in the Knowledge Base which describe several possible solutions to separate networks via Advanced Routing and Forwarding (ARF) or VLAN.
Configuring a stand-alone DNS server per ARF network Since LCOS 8.82, it is possible to configure a standalone DNS server for each ARF network. This is ideal for creating separate logical networks, each of which requires its own DNS server configuration.
The configuration of a Public Spot can be greatly simplified if the payload data sent from the WLAN to the controller is routed through a WLC tunnel. A Public Spot can, for example, provide guests with Internet access in parallel with, but separated from, an internal wireless LAN.
This article describes how to set up a guest network in a WLAN controller by means of VLAN. Even though we are using VLAN, there is no need to activate the VLAN module of the WLAN controller, nor is it necessary to assign a VLAN ID to the management network. Active tagging is implemented by the access points and switches.
