Subject: Query on SNMP Error Fields
...
While the SNMP RFC(1157/2571/SNMPv3) mentions the behavior of "Error Status"
and "Error Index" field as "will be set in the response" and the value of
these fields in all set/get/getnext request is zero, It does not mention if
it is *mandatory* for these fields to have zero in set/get/getnext. Could
these fields be modifiable in set/get/getnext.
As the comments in the ASN.1 say, the values of these two fields are
sometimes ignored. In my opinion it would be legal but unwise to
use non-zero values in those requests. Some over-zealous implementor's
code might actually check for zero, and you'd be in the position of explaining
why your implementation doesn't interoperate with deployed systems.
Be conservative in what you send...
Likewise, if your implementation checks those values in any situation other
than the situations spelled out in the specifications, you could also find
yourself explaining why your implementation doesn't interoperate with
deployed systems.
Be liberal in what you accept....
