Extreme Networks Summit WM User Manual page 17

In addition to the Summit WM Controllers and Wireless APs, the solution requires three other
components, all of which are standard for enterprise and service provider networks:
RADIUS Server (Remote Access Dial-In User Service) or other authentication server
DHCP Server (Dynamic Host Configuration Protocol) If you do not have a DHCP Server on your
network, you can enable the local DHCP Server on the Summit WM Controller. The local DHCP
Server is useful as a general purpose DHCP Server for small subnets. For more information, see
"Setting up the data ports" on page
SLP (Service Location Protocol)

As illustrated in Figure 2, the Summit WM Controller appears to the existing network as if it were an
access point, but in fact one Summit WM Controller controls many Wireless APs. The Summit WM
Controller has built-in capabilities to recognize and manage the Wireless APs. The Summit WM
Controller:
Activates the Wireless APs
Enables Wireless APs to receive wireless traffic from wireless devices
Processes the data traffic from the Wireless APs
Forwards or routes the processed data traffic out to the network
Authenticates requests and applies access policies
