It most certainly does. If you can get a value using SNMP, you can use
MRTG to graph it. Period :)

Here's mine for a 3Com NetBuilderII:

Target[NB2.cpu]:
.1.3.6.1.4.1.43.2.13.8.4.0&.1.3.6.1.4.1.43.2.13.8.4.0:public at NB2

So yes, you need the preceding dot. You also need to specify an
instance - in my case, instance 0.

The OID you are going for is the branch of the MIB which *contains all
instances of that value* - if there was more than one processor you'd
have:

1.3.6.1.4.1.11.2.14.11.5.1.9.6.0
1.3.6.1.4.1.11.2.14.11.5.1.9.6.1
1.3.6.1.4.1.11.2.14.11.5.1.9.6.2

etc.
