Controller-less WLANs

How does Aruba Instant AP classifies the device type of a client ?

Environment : This article applies to Aruba Instant Access Points running Aruba InstantOS 6.2.1.0-3.3.0.0 or higher and managed by Aruba Central.

 

Corporations and individuals are rapidly adopting next-generation smartphones and tablet devices. Wireless networks are becoming the primary method to connect these devices to the enterprise network.
IT administration requires 
greater visibility into the types of devices connecting to network to control the network and bandwidth.
 
Instant AP identifies operating system of a device by reading the user-agent string in HTTP header. HTTP protocol traffic is generated when a user (of a connected client) opens up a browser on the device to access the Internet.
 
Device type for a given MAC address is stored so that subsequent connections from that MAC address need not be fingerprinted. However, these entries should have lifetimes counter associated and are periodically flushed and refreshed.
 
Navigate to Monitoring -> Clients  to view the different client device types as shown in the following figure:

Device Type with "Unknown" are the wireless clients that are associated but did not pass any HTTP traffic for the Instant AP to identify the OS.


The Clients page also displays the PIE graph showing different Device Types and their count irrespective of the SSID they are connected to. Below figure shows a PIE graph:
