[SNMP4J] console tool (SnmpRequest) returns an incorrect value

[Erik Torres Serrano]

Hi, thanks everyone for the responses. I have used the "-p GET" option and it works. Thanks Frank for the terrific SNMP4J!

Best regards,

Erik

Hi Erik,

With the console tool, you have to explicitly specify
the PDU type, since there are no different flavors
of the tool like in NET-SNMP for each PDU type.
The default is GETNEXT, and so, the behavior is
correct.

Simply specify "-t GET" as option and you will receive
the expected result.

Best regards,
Frank
