ARUBA Controller Showing Win 7 client as IPhone device..

Gents,
 
l'm curious about this.. I have a 3600 controller connecting to a external DHCP.. I noticed when I go to monitoring / clients I  can see some IPhones connected to my employees network.. (This is not possible because this SSID is setup to allow laptops no personal phones..
After a full analysis if I check the DHCP server I have the correct name from the host and the IP address but if I go back to the controller and look for the device type it shows up as an IPhone. 
Also airwave is doing the same thing..
 
Any suggestion? maybe a DHCP issue? should I check something ? 
 
Regards,
 
Giovanni Saldarriaga

The user could be using a browser that has an iPhone user agent configured.

Tim, Giovanni, 

As I remember controller clasiffies endpoints with DHCP fingerprint. You can enable debug log and follow the raw fingerprint from the client.

marqs,

 

In the user-table on the controller it uses the "Browser Agent" to show the operating system, NOT the DHCP fingerprint.  To see what browser agent the incorrectly classified user is showing, Giovanni can type "show aaa device-id-cache | include <mac address>":

 

(192.168.1.3) #show aaa device-id-cache | include 00:24:2c:3a:08:37
00:24:2c:3a:08:37  Mozilla/5.0 (X11; Linux i686; rv:5.0) Gecko/20100101 Firefox/5.0                                                                 Wed Aug  3 19:55:32 2011

 

That will determine what application is causing the device to be misclassified.

 

Sometimes something as little as a weather APP causes the device to be misclassified.
