• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.
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.
