<p><strong>Note:</strong> These functions use header (include) files from the
|
||
|
|
library QSYSINC, which is optionally installable. Make sure QSYSINC is
|
||
|
|
installed on your system before using any of the functions. All of the SNMP
|
||
|
|
manager APIs use header file <strong>qtomeapi.h</strong>. You can see this
|
||
|
|
source in source file H, member name QTOMEAPI, in the QSYSINC library.</p>

|
||
|
|
|
||
|
|
<p>SNMP managing applications typically use APIs to establish communication
|
||
|
|
with local or remote SNMP agents, and then call other APIs to retrieve or
|
||
|
|
modify MIB objects managed by those agents. The i5/OS<SUP>(TM)</SUP> SNMP manager APIs
|
||
|
|
accomplish both of these tasks within the same API. Three manager APIs are
|
||
|
|
provided to perform the SNMP GET, GETNEXT, and SET operations. In general, all
|
||
|
|
three APIs are blocked. That is, when the application calls these APIs, the API
|
||
|
|
constructs a proper SNMP message, delivers it to the proper SNMP agent, waits,
|
||
|
|
decodes the response from the agent, and delivers the information to the
|
||
|
|
application. No processing occurs in the application until the API delivers
|
||
|
|
this information or times out. The communications mechanism between the manager
|
||
|
|
APIs and agents uses sockets. Therefore, both systems need to support
|
||
|
|
sockets.</p>
|
||
|
|
|
||
|
|
<p>Application programmers who are writing network management applications can
|
||
|
|
use the snmpGet(), snmpGetnext(), and snmpSet() SNMP APIs to retrieve and set
|
||
|
|
management information base (MIB) data so that they can manage their systems
|
||
|
|
and networks. Programmers should have a strong understanding of network
|
||
|
|
management, SNMP, and some transport protocol such as Transmission Control
|
||
|
|
Protocol/Internet Protocol (TCP/IP).</p>
