Cisco 2106 Wireless LAN Controller
The Cisco 2106 Wireless LAN Controller works in conjunction with Cisco lightweight access points and
the Cisco Wireless Control System (WCS) to provide system-wide wireless LAN functions. As a
component of the Cisco Unified Wireless Network, the 2106 controller presents network administrators
with the visibility and control necessary to effectively and securely manage business-class wireless
LANs and mobility services, such as voice, guest access, and location services.

LANs and mobility services, such as voice, guest access, and location services.
The 2106 controller supports up to six lightweight access points, making it a cost-effective solution for
multi-controller architectures typical of enterprise branch deployments. It may also be used for single
controller deployments for small and medium-sized business environments. The 2106 controller
provides eight Ethernet ports, two of which can provide power directly to Cisco lightweight access
points.

Multiple WLANs with the Same SSID
In controller software release 4.0.206.0, you can configure multiple WLANs with the same SSID. This
feature enables you to assign different Layer 2 security policies within the same wireless LAN. To
distinguish among WLANs with the same SSID, you need to create a unique profile name for each
WLAN.
