SNMP4J : Is it possible to create an OID in the agent (server) MIB from the manager (client)?

Question

I am using SNMP4J Framework and it implements and makes possible the standard SET, GET, GET-NEXT, etc. messages.

For example, with a SET, I can update the value of the MIB OID "1.3.6.1.2.50.0". This works perfectly for me. I can do that using org.snmp4j.Snmp.set(PDU pdu, Target target)

What I want to do now is to CREATE a custom MIB OID (as "1.3.6.1.2.100.0") FROM the client and assign a value to it and not simply update an existing MIB OID value.

Is there any standard SNMP way to do that easily ?

Answer 1

Yes.

But it doesn't make sense in the context of SNMP to "create" a new scalar out of thin air; normally you are setting one already defined with a pre-defined OID, and that OID will usually be shared agent -> manager via a MIB file. Its OID will be the 0th instance (e.g., sysDescr.0).

You can however add/remove rows in a SNMP table (its rows and cells will have OIDs at instance 1, instance 2, etc.); and that SNMP table may have zero rows. The cells in the table can have values.

Here is some background info on SNMP tables.
