Right now our MFD based agent returns MFD_SKIP if an object doesn't
exist, and that's gets translated by net-snmp into a value being
returned who's type is, SNMP_NOSUCHINSTANCE (which is really
ASN__CONTEXT | ASN_PRIMITIVE | 0x1). This seems correct according to the
RFC (A snippet follows).
This works just fine as long as I'm using net-snmp. When one of the
guys here implemented an agent for Windows, there is an event (I forgot
it's name) called something-NOSUCHINSTANCE that equates to the same
value as SNMP_NOSUCHINSTANCE (0x81), but if the Windows agent tries to
pass it to Windows snmp service, it promptly converts it to an error,
and GETNEXT requests stop coming down. The Windows agent he coded for is
the standard service that comes with Windows OS.
I'm not meaning to ask a rhetorical question, but is Windows that
brain dead? What is the proper behavior here???
Thanx, tom.c
/Each variable binding is processed as follows:
1. If the variable binding's name exactly matches the name of a
variable accessible by this request, then the variable binding's
value field is set to the value of the named variable.
2. Otherwise, if the variable binding's name does not have an OBJECT
IDENTIFIER prefix which exactly matches the OBJECT IDENTIFIER
prefix of any (potential) variable accessible by this request,
then its value field is set to `noSuchObject'.
3. Otherwise, the variable binding's value field is set to
`noSuchInstance'./
