There are many weird quirks in the asset management.  The biggest thing is the auto-discovery overrides entered data.  There needs to be a way for the administrator to override without excluding. 

Products - Auto discover overrides the product name.  A good solution would be allow admin to setup products that use a scanned product name.  i.e. Admin sets up a Laptop called Thinkpad 530.  Assigns this to all products that scan as Thinkpad 530, Thinkpad 530c, Thinkpad 530 (9249), etc.

Access Points - Why no ip address?

Routers/Switches - One switch keeps scanning as a Router.  Change the product to Switch.  Rescans as Unknown Router. 

IP Phones - Cisco Login doesn't work.  Assign a Phone as a SPA504g with the correct ip address.  Auto-scan changes the ip address to 0.0.0.1.

Just need to allow the admin to have more control
