Assuming you're using MRTG, if you have a new enough IOS you can poll
the VC stats directly with SNMP. Try something like this:
Target[vc111]: VccInOctets.xx.yy.zz&VccOutOctets.xx.yy.zz:public@router
Where: xx == snmp ifindex
yy == vpi
zz == vci
E.g., given the following:
router> sh atm vc 111
ATM5/0: VCD: 111, VPI: 1, VCI: 11
% snmpwalk -v 1 router public
...
interfaces.ifTable.ifEntry.ifDescr.32 = "ATM5/0-atm layer"
interfaces.ifTable.ifEntry.ifDescr.33 = "ATM5/0.0-atm subif"
interfaces.ifTable.ifEntry.ifDescr.34 = "ATM5/0-aal5 layer"
interfaces.ifTable.ifEntry.ifDescr.35 = "ATM5/0.0-aal5 layer"
...
The target string should look like this:
Target[vc111]: VccInOctets.35.1.11&VccOutOctets.35.1.11:public@router
Older versions (I don't know when this support finally appeared)
required you to write a script and manually pull the necessary info
out of 'sh atm vc' output (dumping it in a file for MRTG to read).
