snmp/mrtg scale/config

I have an mrtg server graphing a bunch of cisco/juniper/whatever hosts just fine, but when I try to graph an epmp link it just seems to not graph right. Here's a graph of one box running about 50M:

Looks like it's maybe off by a factor of 10 somehow? Also, the upload graph just dies after awhile. Here's the relevant parts of my mrtg.cfg file, which was generated by cfgmaker utility:

 Does anyone have an example mrtg.cfg with a working epmp?

Okay, I figured it out, the snmp discovery for some reason misreads the scale, so just add an extra zero like:

MaxBytes[192.168.1.42_1]: 12500000

and it should start scaling fine. HTH someone else working on the same thing :)
