The WiMAX Device sends traps to the SNMP manager when any of the following events occurs:
OMA-DM
When the WiMAX Device initiates communication with the server (often times at start up or after
the first time you turn it on), the server uploads commands, new files (if any), and other
information used by a service provider to customize the WiMAX Device’s features.
Device management works as follows:
1 The server (A) sends out the query (1) to the WiMAX Device (B).
2 The WiMAX Device responds by sending back its credentials (2), to which the server responds with
its credentials along with a string of management operations (3).
3 The client responds to the management operations (4), perhaps confirming file alterations or
confirming receipt of file uploads and so on.
4 The server disconnects from the WiMAX Device once all of its management operations have been
carried out.

OMA-DM Authentication
In order to ensure the integrity of the connection between an OMA-DM server and the WiMAX
Device, communication between the two is encoded using one of three common algorithms. They
are not intended to be used in lieu of proper digital security, but instead as a means of transmitting
