SNMP OID to get trunk port status - different on a EX2300 vs EX3300 - jnxExVlanPortAccessMode

I successfully scan EX3300 and EX2200 switches to get MAC address information via SNMP. Part of that process is to get trunk port status using: 

jnxExVlanPortAccessMode

-or-

1.3.6.1.4.1.2636.3.40.1.5.1.7.1.5

This does not work on an EX2300 (as well as many other OID's - which really sucks).

I've tried searching Junipers SNMP Mib Explorer but can't find the correct OID. Has anyone successfully gotten the trunk status out of a EX2300 and willing to share that OID?
