1. Stellar Enterprise WLAN Global Overview

2. WIFI Enterprise Centralized management with OV2500
Via OV2500 HTML 5.0 interface:
configurations synchronization  
AP-Group Management Interface
Notifications
Guests Captive Portal, BYOD 1
RF management between neighboring APs. 3
OmniVista
Up to 4000 APs
On APs:
Data plane
Control plane
Authentication Management
Local ACL management, etc. 2

3. WIFI Enterprise High level workflow overview
AP Discovery
Automatic creation of a network topology with AP / switch relationship
System configuration by AP Group
Configure radio by ap or AP Groupe
Configure ssid and apply to AP Group

4. WIFI Enterprise Generic topology
DHCP provides IP scope for APs (management) and SSID (data).
The DNS provides the name resolution service for APs (management) and for SSID (data).
DHCP
The management VLAN carries the signaling frames (mcats or ucast) between the APs of a group.
The routing functions (inter VLAN and others) its carried by the aggregation or core switch .
DNS
The switch ports are configured to accept the SSID TAGs and the Management VLAN as the port's default VLAN.
OV UPAM
The management VLAN is NOT tagged by the AP
Omnivista APs and global configuration
UPAM provides Guest CP and BYOD
Each SSID is extended to the LAN via a 802.1q Tag

5. WIFI Enterprise Ap discovery and registration
Service DHCP
1. Boot of a « empty » AP
2. l’AP performs a DHCP request.
3. DHCPD has to respond with a “138” option specifying the IP of the OV2500
4. The AP contacts the OV2500 server and is registered.
7. Configuration of the AP (Proprietary Protocol secured using TLS).
NOTE
The mode of operation is "hard-coded" at the first boot:
If the AP obtains option 138 => OV mode is hard coded
If AP does not get option 138 => AP group mode is hard coded
Only a factory reset of the AP can change the initial mode

6. WIFI Enterprise AP DISCOVERY AND REGISTRATION
New AP
PERMITTED ?
LICENCES
AVAILABLE ?
Yes
Yes
Group Assignment and Configuration
Yes
OK ? No No No
NOT AUTHORIZED NO
LICENCES
AP MANAGED BY OV2500
Managed AP
Unmanaged AP

7. WIFI Enterprise OV2500 AP registration GUI
The AP can be manually registered. APs created / imported manually are always “trusted”.
Automatic registration option for new APs
By default, new APs are not automatically registered and require a "Trust" action in the registration tool (UnManaged AP section)
The admin can import APs via an excel spreadsheet

8. WIFI Enterprise AP Group configuration overview
AP management via OmniVista always implies configuration push to an AP group.
RF Profile
Country/Region
Dynamic Load Balance
Background Scanning
Per Band Info
NTP
The "base" RF parameter points to a specific Radio profil
Syslog
The AP group shares global system settings
RF Profile 2
Some APs in a group may have the same AP Group but different RF parameters
