Identify Version of Docsis with SNMP

Is there a way to differentiate between docsis 2.0 and docsis 3.0 modem with snmp?

The snmpget, snmpwalk,

The snmpget, snmpwalk, snmpset also work with d2 or d3 modems,
but of cource the SNMP oids (which modem understands) depend on the type of modem.
( vendor- and docsis-specific oids )

Identify version

So let me improve my question.
Is there an OID to identify what version of cable modem I am dealing with. Docsis 2.0 and Docsis 3.0 have different Mibs. And Im writing code to pull information from all the cable modems. I need to know if this is a 2.0 cable modem or a 3.0 cable modem so I know which OIDs to pull.

Snmpwalk the modem with that

Snmpwalk the modem with that OID, which is in the DOCS-IF3-MIB. (for example: docsIf3CmStatusValue)
If you get the value, then the modem is D3, otherwise you will get "No Such Object available...." response.
