Bandwidth Managment 2

[abovebrd]

Can anyone recommend a way to view IP usage by IP address.

I was thinking of using mrtg for this purpose. Can someone recommend another method.

My goal is to view statistics (graphs, numbers whatever)of how much bandwidth each Ip address is using within a specific subnet.

Help, please !

Specifically answering your question, MRTG is a great network management tool, however it will only give you the amount/percentage of bandwidth utilization for a specific SNMP based IP address and/or interface. It will not give you protocol specific utilization. In order to accomplish this you need additional management tools such as a Network Associates Sniffer or a network management program (HP Openview, Ciscoworks 2000, Netsys) used in conjunction with an RMON II probe. A Sniffer will allow you to capture data off the wire from device to device, device to subnet, device to protocol, etc,. Assuming your devices are RMON complient, without a probe (hardware or software) you'll only get the first four groups: (statistics, history, alarms and events), normally referred to as RMON I or RMON lite. The data you are requesting is in the last five groups, specifically the Hosts Top N or Traffic Matrix. This can only be retreived with an RMON II probe. In my opinion, the best way to accomplish your goal is with a Network Associates Sniffer. It's flexable, can be used to retreive a tremendous amount of information, great for baselining and troubleshooting, and is a heck of a lot cheaper than Cisco's network management software and the overpriced RMON probe. Hope this helps.
