Try using the IP address of each subinterface.  In terms of bandwidth, give it the PVC size.  Also, you can watch spikes by using the AbsMax option.

Here's an example:

Target[percent_x.x.x.x]: /x.x.x.x:public at routername-interface * 100 / 8000
RouterUptime[percent_x.x.x.x]: public at routername-interface
SetEnv[percent_x.x.x.x]: MRTG_INT_IP="x.x.x.x" MRTG_INT_DESCR="ATM3/0/0.3"
Directory[percent_x.x.x.x]: routername-interface
Maxbytes[percent_x.x.x.x]: 100
Absmax[percent_x.x.x.x]: 200
Unscaled[percent_x.x.x.x]: dwmy

x = ip address
public = substitute your public community string

Also, I measure in bits, not bytes so that's what the "* 100/8000" is at the end of the target line.  8000 comes from dividing the PVC amount by 8.  Example:  My PVC on this circuit is 64K.  That's 64000 bps.  Divide by 8 and you get 8000.  The Maxbytes at 100 has to be in there too.  

Finally, the Absmax option is used if you want to measure spikes above the PVC amount with the max being the port speed.  Here, the factor is 200 which translates to 2 times the size of the Maxbytes or PVC.  Therefore, my port size is 128K.

This works great for me.  I currently monitor 50 ATM circuits with this exact setup.

Adam

Sorry Chris,
but me and (i think ^_^) also Theresa aren't writing about
Virtual-Access Interfaces, but virtual or also named sub
interfaces.

Like for ATM: ATM3/0.10134
and for Ethernet: FastEthernet2/0.2
This kind of FastEthernet subinterfaces is
a virtual interface for a VLAN.

Bye,

        Ste.
