Some devices aren't displaying the device type within the monitoring page

Some of the devices that are wirelessly connected to my 650 controller don't show the device type when I'm looking at the clients in the monitoring page.  Is there any reason why they wouldn't be displayed?

 

I am running version 6.1

Original Response:

The device type listed in the client table can be determined by one of two things.   The first is the DHCP fingerprint.  The controller does not have to be the DHCP server, but needs to see the request.    If the client is running an odd OS type that is not in the database or has a static IP address or the AP is in bridgd mode this component would not reveal the device type.   The second is through HTTP header analysis.  Once the client attempts an HTTP request, additional information can be obtained about the device type (Windows XP vs Windows for example).

I hate to nitpick, but the OS Type displayed in the controller's user table is ONLY discovered through http requests and NOT dhcp fingerprints.  That is why devices like VOIP phones and others that do not open browsers will NOT have the OS displayed in the controller's user table.  

 

The "show aaa device-id cache" command will show what devices have sent http and were identified in the user table.  You can still use the DHCP fingerprint to create a user derivation role for devices that do not use http change their role.  Their operating system will not be displayed in the user table of the controller if they do not use http, however:

 

 

(host) #show aaa device-id-cache

Re: Some devices aren't displaying the device type within the monitoring page

Bringing up this one. We have wireless scanners connecting, not sending HTTP headers. Is it possible to add a custom device type based on the scanners MAC OUI? If not, can you create a rule which will set the Device Type to "SCANNER" when the MAC address starts-with xx:xx:xx....

That is not possible, no.
