The WiMAX Device sends traps to the SNMP manager when any of the following events occurs:

download new files, CI command "sys reboot", etc.).

 

 

 

6b

A trap is sent with the message of the fatal code if

 

 

the system reboots because of fatal errors.

 

 

 

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:

1The server (A) sends out the query (1) to the WiMAX Device (B).

2The 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).

3The client responds to the management operations (4), perhaps confirming file alterations or confirming receipt of file uploads and so on.

4The 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
