[SNMP4J] About SNMP4J

[Frank Fock]

Hi Mauricio,

a SNMP engine ID must have a length of at least 5 bytes and may
have a length up to 32 bytes. Your engine ID configuration results
in two bytes (0x12 and 0x34) which is not what you have used in
SNMP4J (0x1, 0x2, 0x3, and 0x4). Please use the same engine ID
with at least five bytes for both.

Best regards,
Frank
