<p>The <strong>mkDPItrap()</strong> function makes a DPI trap packet and
|
|
returns a pointer to the packet.</p>

<h3>Authorities and Locks</h3>

<!-- Use this if there are no authorities and locks. -->

|
<h3>Parameters</h3>
|
|
|
|
<dl>
|
|
<dt><strong>generic</strong></dt>
|
|
|
|
<dd>(Input) The generic trap type. The range of this value is 0 through 6,
|
|
where 6 (enterpriseSpecific) is the type that is probably used most by DPI
|
|
subagent programmers. The values 0 through 5 are well-defined standard SNMP
|
|
traps.<br>
|
|
<br>
|
|
</dd>
|
|
|
|
<dt><strong>specific</strong></dt>
|
|
|
|
<dd>(Input) The (enterprise) specific trap type. This can be any value that is
|
|
valid for the Management Information Base (MIB) subtrees that the subagent
|
|
implements.<br>
|
|
<br>
|
|
</dd>
|
|
|
|
<dt><strong>packet_p</strong></dt>
|
|
|
|
<dd>(Input) A pointer to a chain of snmp_dpi_set_structures that represents the
|
|
varbinds to be passed with the trap. This partial structure will be freed by
|
|
the mkDPItrap() function; therefore, you cannot refer to it anymore on
|
|
completion of the call. A NULL pointer means that there are no varbinds to be
|
|
included in the trap.<br>
|
|
<br>
|
|
</dd>
|
|
|
|
<dt><strong>enterprise_p</strong></dt>
|
|
|
|
<dd>(Input) A pointer to a NULL-terminated character string that represents the
|
|
enterprise ID (OBJECT IDENTIFIER) for which this trap is defined. A NULL
|
|
pointer can be used. In this case, the subagent Identifier as passed in the DPI
|
|
OPEN packet will be used when the agent receives the DPI TRAP packet.
|
|
|
|
<p><strong>Note</strong>: This OID must not end in a period (.).</p>
|
|
</dd>
|
|
</dl>
|
|
|
|

|
|
<h3>Return Value</h3>
|
|
|
|
<table cellpadding="5">
|
|
<!-- cols="10 90" -->
|
|
<tr>
|
|
<td align="left" valign="top"><em>value</em></td>
|
|
<td align="left" valign="top">The value returned is a pointer to the DPI
|
|
packet.
|
|
|
|
<p>If successful, then a pointer to a static DPI packet buffer is returned. The
|
|
first 2 bytes of the buffer (in network byte order) contain the length of the
|
|
remaining packet. The <strong>DPI_PACKET_LEN()</strong> function can be used to
|
|
calculate the total length of the DPI packet.</p>
|
|
</td>
|
|
</tr>
|
|
|
|
<tr>
|
|
<td align="left" valign="top"><em>NULL</em></td>
|
|
<td align="left" valign="top">If unsuccessful, then a NULL pointer is
|
|
returned.</td>
|
|
</tr>
|
|
</table>
|
|
|
|
<p>Be aware that the static buffer for the DPI packet is shared by other
|
|
mkDPI<em>xxxx</em>() functions that create a serialized DPI packet.</p>

<h3>Usage Notes</h3>
|
|
|
|
<p>The <strong>mkDPItrap()</strong> function is used at the subagent side to
|
|
prepare a DPI TRAP packet. The resulting packet can be sent to the SNMP
|
|
agent.</p>
|
|
|
|
<p>Unnecessary free operations may result in an MCH6902 (type 2). If this
|
|
occurs, remove the call to <strong>fDPIset()</strong>.</p>
