Question : MRTG eth0: HOW-TO

I have a webserver, have 128 IP's, want to monitor traffic on all of them. They are all on eth0 from eth0 to eth0:126.
My brain hurts now ... How do I setup mrtg to check traffic on those interfaces ? I don't have SNMP (I guess:P) Just want to make a graph of total usage.
Any example .cfg would be reaaaaaly nice :)
Thanks !

Depends on the OS of the server how you enable it.
Once you do, then you access it through mrtg MySNMP$trinG@
