Hi Aswin,
Your index definition proves my guess.
The index you create does not match your definition.
You can find examples in the SNMP4J-Agent code
if you search for "toSubIndex(false)". That is a method
of OctetString which creates a sub-index OID value
from an OCTET STRING.
Also read the SNMP RFCs about the INDEX SMI construct
for more details.
Best regards,
Frank
