Hi Frank,
I tested using SNMP SimpleTester. One test case in that specifies that the SNMPv2C agent is expected to return a noSuchObject value for Get requests if request is sent with following condition.
:: In the case of a tableEntry with 5 columns and a get request will be sent for tableEntry.6.
I think this is a valid test case. Please correct me if I am wrong.
Regards
Nidhin

Hi Nidhin,
OK, but this is the expected result, since snmpTargetAddrEntry
is a registered ManagedObject of the TestAgent.
Can you reproduce it with an OID for which no registration
exists in the path to the root OID?
Best regards,
Frank
