For a Centralized site using AP39xx or AP5xx access points, a UDP-based protocol enables
communication between an AP and ExtremeCloud Appliance. The UDP-based protocol encapsulates IP
traffic from the AP and directs it to the appliance. The appliance decapsulates the packets and encrypts
(IPSec)[Default AP and appliance communication] and routes them to the appropriate destinations,
while managing sessions and applying roles.
For a Distributed site using AP76xx, AP8xxx, or AP5xx access points, the communication is handled
through the WebSocket protocol for configuration and through HTTPS POSTs for statistical data.
Sites Overview
Use sites to define boundaries for fast roaming and session mobility without interruption. A site
represents a physical, geographic area in your network, and defines a roaming domain. As the top-level
element in the ExtremeCloud Appliance data model, the site runs Sessions Manager and RF Manager
functions for all RF Domains in the site. Define the licensing domain for the site by selecting the
Country
option, and define the AP platforms available to the site by selecting the site configuration, either
Distributed
or
Centralized
.
A site in ExtremeCloud Appliance is composed of one or more device groups. Each device group holds
one or more APs. The APs in a device group must have the following in common:
•
AP Model
•
Configuration Profile
•
RF Domain
•
Regulatory domain and configuration type, which is defined at the site level.
A Centralized site can include multiple device groups all in a single RF domain, or multiple device
groups, each group in a unique RF domain. A Distributed site can only have a single RF domain.
A site also includes the following:
•
One or more floor plans. Floor plans are unique to each site.
•
Site metadata used to place the site on a Google map.
•
List of switches associated with the site.

Centralized Site
A Centralized configuration uses ExtremeWireless AP models AP39xx, and AP5xx. Each Wireless AP
opens an IPSec tunnel to ExtremeCloud Appliance, and the Session Manager and RF Management
policy run on ExtremeCloud Appliance.
