You should get a bit more specific:
- What webserver (Apache/IIS) are you running ? -> if IIS, there's afaik no way to graph single virtual instances with SNMP without going the painful perfmon-way)
- What Firewall brand/model/version ? 
Forget about the 2980, you can only graph the physical switch interfaces' traffic, no IP-address related things.

IP-Accounting-like stuff is always quite difficult to graph with MRTG and more a job of flow-analysis but there 
may be a way depending on what equipment you have (NBAR,CAR etc.), the most likely way is from the webserver directly..

Subject: [mrtg] MRTG and a Multihomed webserver.


I am trying to monitor bandwidth usage to 10 websites I have on one web
server.  Each website has it's own IP address but bound to one card on
the web server.  I do not have access to the core router to get this
information but I do have access to the firewalls and cisco 2980
switches, and the web server.  Basically I want to graph the bandwidth
usage based on IP address.  What is the best way to do this?
 
Thanks
