A Centralized site topology allows seamless roaming within one geographic location. A single site
supports multiple device groups with a total of 200 to 4,000 APs [in appliance High Availability mode]
for the site. With a Centralized site, ExtremeCloud Appliance performs as the management server and
the session manager. The RF domain manager resides locally on ExtremeCloud Appliance.
Although session management is centralized at the appliance, users can select the best topology for
network access:
•
Bridged@AC (Tunneled for VLAN, attached at ExtremeCloud Appliance)
•
Bridged@AP
•
Fabric Attach (Bridge@AP with an I-SID mapping).
The following AP models can be deployed in a Centralized site:
•
AP505i
•
AP510i/e
•
AP560i/h
•
AP3917i/e/k
•
AP3916ic
•
AP3915i/e
•
AP3912i
•
AP3935i/e
•
AP3965i/e

Use Case: Large Centralized Site
Scenario: A large centralized site is composed of two separate buildings. Each building supports a
unique configuration with its own policy requirements. Clients need the ability to roam between
buildings without session interruption.
Solution: Create a Centralized site, defining multiple device groups. Each device group will support a
unique profile configuration.
Distributed Site
A Distributed configuration uses ExtremeWireless WiNG APs. Each WiNG AP opens a WebSocket to
ExtremeCloud Appliance and Session Manager and Smart RF Manager run on one of the APs in the site.
All APs in a Distributed site have one RF Domain.
A Distributed site topology allows seamless roaming. Sites support multiple device groups with up to
200 APs associated with each site. With a Distributed site, ExtremeCloud Appliance performs as the
management server, and one AP has the elected role of session manager and RF domain manager.
Network trac is bridged locally at the AP, no trac forwarding back to ExtremeCloud Appliance.
The Fabric Connect network is supported by the AP, and switches can be managed from ExtremeCloud
Appliance over HTTP.
