[SNMP4J] SNMP4J Digest, Vol 90, Issue 11

[Harsha H R]

Hi Frank,

I'm not clear on what is the bug here!

Below is the extract from RFC 1905(Protocol Operations
                          for Version 2 of the
              Simple Network Management Protocol (SNMPv2)

On page number 15

(2)  If the requested variable binding's name does not lexicographically
     precede the name of any variable accessible by this request, i.e.,
     there is no lexicographic successor, then the corresponding
     variable binding produced in the Response-PDU has its value field
     set to `endOfMibView', and its name field set to the variable
     binding's name in the request.

(2)  If there is no (i)-th lexicographic successor, then the
     corresponding variable binding produced in the Response-PDU has its
     value field set to `endOfMibView', and its name field set to either
     the last lexicographic successor, or if there are no lexicographic
     successors, to the (N + r)-th variable binding's name in the
     request.

And the below response from the agent is in-line with RFC. 

Are you saying that endOfMibView is not handled OR the agent returning the response as below itself is incorrect ?

Regards,
Harsha

Hi Harsha,

You will have to write your own TableUtils class to change this behavior.
But careful, there are many buggy agents like yours in the field.

In your case, the bug is harmless (although it violates the standard).

But other agents return lesser OIDs which can cause endless loops.
Therefore, this check cannot be deactivated.

Best regards,
Frank
