Hi
During system test of my snmp manager implementation i ran into a
problem with the pdu size. My application creates a snmp get request
containing 55 get's resulting in a packet length of 2000+ bytes.
I've been using the
"target.setMaxSizeRequestPDU(SnmpConstants.MIN_PDU_LENGTH);" setting and
thus expected that pdu packets never excedded this value. But now that
i've investigated my problem, i see that the max-size value only is used
by TableUtils.
At the moment I'm assuming that i need to make something like the code
snippet below to solve my problem. Is there a simpler solution than this
?
Somehow i expected that this would be handled by snmp4j since it it is
possible to configure max size. Maybe at least an exception should be
thrown id a pdu is exceeding the configured size ?
Kind Regards

Code snippet:
------------------------------------------------------------
Vector<PDU> pduList = new Vector<PDU>();
PDU pdu = createPDU();
pduList.add(pdu);
for (int i = 0; i < params.size(); i++)
{
VariableBinding vb = new VariableBinding(new
OID(params.getParams(i).getParamIdAndInstance()));
pdu.add(vb);
if (pdu.getBERLength() > target.getMaxSizeRequestPDU())
{
pdu.trim(); //removes previous added vb
pdu = m_snmpInfo.createPDU(); //create new pdu
pduList.add(pdu);
pdu.add(vb);
}
}
for (int n = 0; n < pduList.size(); n++)
{
m_snmp.get(pdu, target, r.getSyncObject(n), r); // using
asyncroneous calls
}
