<h3>Usage Notes</h3>
|
||
|
|
|
||
|
|
<p>The <strong>mkDPIAreYouThere()</strong> function creates a serialized DPI
|
||
|
|
ARE_YOU_THERE packet that can then be sent to the DPI peer (normally the
|
||
|
|
agent).</p>
|
||
|
|
|
||
|
|
<p>If your connection to the agent is still intact, the agent will send a DPI
|
||
|
|
RESPONSE with SNMP_ERROR_DPI_noError in the error code field and zero in the
|
||
|
|
error index field. The RESPONSE will have no varbind data. If your connection
|
||
|
|
is not intact, the agent may send a response with an error indication, or may
|
||
|
|
not send a response at all.</p>
