OID             frInOctets      .
OID             frOutOctets     .
OID             frRecBECNs      .
OID             frRecFECNs      .
OID             frIndex         .
OID             frDlci          .

The hard thing about getting the frame stats, is building the config file.
You are probably going to have to do that outside. of cfgmaker.

you need the ifIndex, the frIfIndex (which maps to the frame-relay host),
and the frDLCI OID.

The various sub-interfaces can be specified as 
for gathering stats.  So say you have a sub interface serial4.121 that you
need to graph.  You'd specify that as 
FECNs: .
because 4 is the frame host interface, and 121 is the DLCI.  But that
interface might be ifIndex interface 34, because those get counted in a
straight line from zero.

If you play with it enough, you'll get it working.
