If you have EOS or XOS-G2 switches, it can even resolved, when nodealias is enabled.

The Device Type can be set by API call = if you know list of your printers then the device type can be updated.

How does it work with the api call ? We have Extreme Analutics but most of our printers are printing with port 9100

  • There is plan to have analytics based profiling very soon = official feature
  • Today you can define your own application "Printing" based on application fingerprint. Periodically check clients using your application "Printing" and change the profile by API call. This can be done quite easily by workflow or scripts inside of Extreme Management Center
here is example of RestAPI call: https://MyXMC:8443/axis/services/NACEndSystemWebService/setDeviceTypeByMAC?macAddress=80:D6:05:4A:D6:C4&deviceType=Nokia-Brick&isAccurate=true&reason=Profile_changed
