[AGENT++] Size limit of an OctetString inside a MibTable ?

[Jacquemin, Jean-Philippe]

Dear All,

 

I would like to know what is the size limit of a DisplayString contained
into a MibTable ?

I use to populate my table with security certificates of max size of
3KB. I now have to use 9KB data (in the future maybe up to 64KB) and I
do get a 'SNMP protocol error').

 

Table creation:

 

  if ((pMibTable = new MibTable(*m_poidCertificateEntry)) != NULL)

  {

    /* build up the columns */

    for (dwColCount = 1; enReturnValue == CError::eNoError

                         && dwColCount <= CertificatesTable.Size.eCol;
++dwColCount)

    {

      sprintf (strOidx, "%lu", dwColCount);

      if (dwColCount == CertificatesTable.Cols.eIndex)

      {

        if ((pInt32 = new SnmpInt32((SDWORD) 0)) != NULL

            && (pMibLeaf = new MibLeaf(Oidx(strOidx), READONLY, pInt32))
!= NULL)

        {

          pMibTable->add_col(pMibLeaf);

        }

        else enReturnValue = CError::eMibBuildingError;

      }

      else if (dwColCount == CertificatesTable.Cols.eCertificateName)

      {

        if ( ((pOctetStr = new OctetStr((BYTE*)"None",
MAX_CERTIF_NAME_LENGTH)) != NULL)

        && ((pMibLeaf = new MibLeaf(Oidx(strOidx), READONLY, pOctetStr))
!= NULL) )

        {

          pMibTable->add_col(pMibLeaf);

        }

        else enReturnValue = CError::eMibBuildingError;

      }

      else // certificate !!

      {

        if ( ((pOctetStr = new OctetStr((BYTE*)"None", 3000)) != NULL)

        && ((pMibLeaf = new MibLeaf(Oidx(strOidx), READONLY, pOctetStr))
!= NULL) )

        {

          pMibTable->add_col(pMibLeaf);

        }

        else enReturnValue = CError::eMibBuildingError;

      }

    }

 

Thanks in advance for your help!

 

 

Best regards,

 

Jean-Philippe
