[AGENT++] Unexpected request type for SNMP set

[Dave White | Networking]

David Nedde,

I think you need to distinguish between version 1 and version 2 of the SNMP
protocol.  Version 1 set-request has the same value as version 2 response.
Look deeper into the PDU to also check the version.  The values for
sNMP_PUD_SET defined in snmp_pp/smi.h are for v2.  The raw PDU received in
the loop is probably v1.  As stated by Jochen, the request type gets changed
before being processed.

Regards,
Dave

without looking at the agent++ code: The process_request() function
changes the request type before answering the request, so check the type
before calling process_request().

Request* req = reqList->receive(0);
if ( req )
{
     bool save = false;
     if ( req->get_type() == sNMP_PDU_SET )
         save = true;
     mib->process_request(req);
     if (save)
         mib->save_all();
 }

Regards,
  Jochen
