[SNMP4J] How to write to a SNMP table?

[Frank Fock]

Hi,

As the Javadoc of TableUtils.createRow explains, this method can only be 
used with
tables that have a RowStatus column. Since your table does not have such 
a column,
it will not work with such a table.

The rowIndex is the OID suffix that identifies the table row. In your 
case it is
the MacAddress + IfIndex encoded as an OID.

Best regards,
Frank
