Class: TSNMPSend

RFC: 1157

Features:

• support for all method of SNMP protocol, except traps. (for trap support is separate unit)
• supported all possible data types (integers, strings, OIDs, IP addresses, etc...) for all methods (SET, GET, etc...).
• support for multiparameter queries.
• native code, not need any support DLLs.

• In all cases you must have SNMPsend in your uses.
• For simple query for one MIB OID from your applications call function SNMPGet. Not need any more. This function create needed object, query SNMP host and return response as string.
• If you can query for multiple MIB OIDs or implement any method, see example:

  {you must create object for SNMP session}
  SNMP:=TSNMPSend.Create;
  try
    {set address of SNMP server}
    SNMP.Host:=SNMPHost;
    {build query...}
    {set COMMUNITY for grant accessto SNMP server}
    SNMP.Query.Community:=COMMUNITY;
    {set type of PDU to define requested SNMP operation. Possible values are: PDUGetRequest, PDUGetNextRequest and PDUSetRequest}
    SNMP.Query.PDUtype:=PDUGetRequest;
    {define query OIDs...}
    {add MIBOID as string to set of MIBs}
    SNMP.Query.MIBAdd(FirstMIBOID,'',ASN1_NULL);
    SNMP.Query.MIBAdd(SecondMIBOID,'',ASN1_NULL);
    //...etc...
    {send query to SNMP server}
    if SNMP.DoIt then     {In Reply structure is response from SNMP server}
      {set Value with value of searched MIBOID}
      Value:=Snmp.Reply.MIBGet(MIBOID);     //...etc...
    else     {error connecting to server} ;
  finally
    {destroy SNMP object}
    SNMP.Free;
  end;
