Summit WM Controller, Access Points, and Software Solution

topology and network elements

The following figure illustrates a typical configuration with a single Summit WM Controller and two

Wireless APs, each supporting a wireless device. A RADIUS server on the network provides user

authentication, and a DHCP server assigns IP addresses to the Wireless APs. Network inter-connectivity

is provided by the infrastructure routing and switching devices.

The Summit WM Controller supports the following network elements.

● RADIUS Server (Remote Access Dial-in User Service) – An authentication server that assigns and

manages ID and Password protection throughout the network. The RADIUS server system can be

set-up for certain standard attributes such as filter ID, and for the vendor specific attributes (VSAs).

The Summit WM Controller supports external RADIUS server.

● DHCP Server (Dynamic Host Configuration Protocol) – A server that assigns the IP addresses,

gateways, and subnet masks dynamically. The external DHCP server depicted in Figure 2-1 is

primarily utilized to provide addresses to infrastructure equipment such as APs. The IP addresses to

the mobile devices are provided by the built-in DHCP server of Summit WM Controller. You can

also configure the Summit WM Controller to relay DHCP requests to the external DHCP server.

● SLP (Service Location Protocol) – A service discovery protocol that allows computers and other

devices to find services in a local area network without prior configuration. The client applications
