[AGENT++] Unavailable variables

[Fehde, Marcus]

Hi Mads,

you can do this that way, but "resourceUnavailable" is not valid in context of an GET-request.
The appropriate error is "generalError" which will cause that the whole PDU is cancelled.
As workaround you may return a "noSuchObject" exception for the affected variable bindings, but this is not semantically correct.
Nevertheless it is bettern than using a wrong error status code.

Regards,
Marcu

Hi Mads,

You can set the error status by using the Request instace directly:

void myMibLeaf::get_request(Request* req, int index) {
   if (...) {
      req->error(index, SNMP_ERROR_RESOURCE_UNAVAIL);
   }
...
}

To add a row in the snmpTargetAddr table you will first have to add a row in the snmpTargetAddrParamsTable to able to reference that entry in your row. Try creating the rows using createAndWait(5) row status. Then you can set the values step by step. Make sure that the TAddress and TDomain values matches.

That should do the trick.

Best regards,
Frank
