Wi-Fi Array

(provided by the Wi-Fi Array) or external. An external RADIUS

server offers more functionality and is recommended for large

Enterprise deployments.

When using this method, user names and passwords must be

entered into the RADIUS server for user authentication.

 MAC Address ACLs (Access Control Lists)

MAC address ACLs provide a list of client adapter MAC

addresses that are allowed or denied access to the wireless

network. Access Control Lists work well when there are a limited

number of users — in this case, enter the MAC addresses of each

user in the Allow list. In the event of a lost or stolen MAC

adapter, enter the affected MAC address in the Deny list.

Q. Why do I need to authenticate my Wi-Fi Array units?

A. When deploying multiple Wi-Fi Arrays, you may need to define which

units are part of which wireless network (for example, if you are

establishing more than one network). In this case, you need to employ the

Xirrus Management System (XMS) which can authenticate your Arrays

automatically and ensure that only authorized units are associated with

the defined wireless network.

Q. What is rogue AP (Access Point) detection?

A. The Wi-Fi Array has a dedicated radio, IAP abg(n)2, which constantly

scans the local wireless environment for rogue APs (non-Xirrus devices

that are not part of your wireless network), unencrypted transmissions,

and other security issues. Administrators can then classify each rogue AP

and ensure that these devices do not interrupt or interfere with the

network.
