I have an office building that acts as an ISP and distributes public ip addresses to each of the internal separate offices. 3 bonded TI lines come in to the main router that is then connected to a pair of switches. We have about 20 IP addresses in use and are having some major bandwidth issues... one of the internal offices is really putting a strain on the network and we want to find out who. How can I go about this? I only have access to the switch via SNMP an am hoping to monitor bandwidth usage per IP / switch port.
Any help is VERY appreciated!
