[SNMP4J] Problem with Table Utils

[Frank Fock]

Hi Ryan,

The upper and lower index are the row's index value not a column OID.
The MacAddress index of your example is an OCTET-STRING of max. length 16.
Thus a valid lower index would be "0.0" for example. But you can leave 
them as
null to get startet as well.

Hope this helps.

Best regards,
Frank
