[mrtg] How to monitor traffic on Cisco 675 Routers

[Nate Carlson]

Has anyone figured out a way to monitor traffic utilization on a Cisco
675 ADSL router? Here's what I get when I try to run cfgmaker on one:

# Add a WorkDir: /some/path line to this file

This router is running CBOS 2.2, which is the newest. Is the 'tooBig'
error status coming from the router or snmpwalk? (I'm kind of new to
SNMP..)    Thanks!
