Chapter 12 Maintenance The WiMAX Device sends traps to the SNMP manager when any of the following events occurs: Table 80 SNMP Traps TRAP # TRAP NAME DESCRIPTION 0 coldStart (defined in RFC-1215) A trap is sent after booting (power on). 1 warmStart (defined in RFC-1215) A trap is sent after booting (software reboot). 4 authenticationFailure (defined in A trap is sent to the manager when receiving any RFC-1215) SNMP get or set requirements with the wrong community (password). 6 whyReboot A trap is sent with the reason of restart before rebooting when the system is going to restart (warm start). 6a For intentional reboot: A trap is sent with the message "System reboot by user!" if reboot is done intentionally, (for example, download new files, CI command "sys reboot", etc.). 6b For fatal error: 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: 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. Figure 103 OMA-DM Data Management B 2 1 3 A 4 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 178 WiMAX Device Configuration User's Guide
