[SNMP4J] Issues with SET on a read-write column

[Frank Fock]

Hi,
I guess that you have chosen the wrong index for your SET operation. If you would have included the INDEX definition I could have checked it.
OCTET STRING index columns have variable length and thus need an additional length sub-id if not specified otherwise for the last sub-index.

Best regards
Frank
