[AGENT++] agent created with cmd_exe_mib doesnt' recognize the get request for OID 1.3.6.1.4.1.4976.6.1.2.2.2.1

[Frank Fock]

Hi Ravi,

You can now download the AGENT++ MIB files also from the 
https://agentpp.com/download.html
page.

The next AGENT++ release will also contain the MIB files again.

A table is not accessible object. So if you run a GET request on a table OID
you will always get a noSuchName (SNMPv2c or later) error.
You will have to access an instance of a row in the table (you can use GETNEXT to find
one). I f there isn’t one - which is the default for new/generated tables then you 
either can create a row via SNMP SET using the RowStatus column or create
the row programmatically in the agent.

Best regards,
Frank
