Chapter 3: Overview of WLAN deployment
The current release of Avaya WLAN supports the following deployment models.
• WLAN Overlay
In the Overlay deployment, the Wireless Controller (WC) 8180 controls/manages Access Points (AP)
over a control channel and data is tunneled between the APs and the controller over an access
tunnel. Two or more WCs in the domain form a cluster, with a mesh of control channels and data
tunnels between each other.
• WLAN Unified Access
In the Avaya VENA Unified Access deployment, the wireless controller deploys in the control-plane
mode of operation of the 8180 platform. This device then hosts only the wireless control function and
is called a wireless control point (WCP). A switch such as the Avaya ERS 8600/8800 introduced into
the network, tunnels traffic (data) and is known as the wireless switching point (WSP). The APs and
WSPs tunnel traffic between each other over an access tunnel and the WSPs tunnel traffic between
each other over a mobility tunnel.
Avaya implemented this solution by combining the functionality of the Avaya WC 8100 with the Avaya
Ethernet Routing Switch 8800/8600 (ERS 8800/8600).
