Re: Is it possible to have write-only MIB item?

In principle, it is possible to have a write-only MIB object, yes.
This would presumably return 'noSuchObject' to a GET request,
and be skipped over entirely for a GETNEXT request.

However, I can imagine some management applications
might be confused by be asked to SET an object which
doesn't seem to exist.  You might do better to have this
object return a standard value.  E.g. see the definition of
UCDErrorFix in the UCD-SNMP-MIB

In either case, your MIB should clearly define the results
of attempting to read such a "write-only" object.

What do you mean by "does not work" ?
What exactly are you doing, and what happens?

Note that Counter-syntax objects can *not* be the target of SET requests.
They are inherently read-only.
   See the penultimate paragraph of RFC 2578, section 7.1.6
