Thanks Robert - I've added this line to my /etc/mrtg/mrtg.cfg:

Target[sg00wr1s002fecns]: .<mystring>@sg00wr1.corning.com
MaxBytes[sg00wr1s002fecns]: 1250000
Title[sg00wr1s002fecns]: Frame-Relay Traffic Analysis
PageTop[sg00wr1s002fecns]: <H1>FECN count for SG00WR1 S0/0.2 - PVC to SNAP S9/0.11</H1>

and MRTG is barking at me with this:

I found the by walking the router with GetIF. (Great tip guys!)

Any ideas?? What am I doing wrong?
