I have a 3550 & 2960 switch that I have Vlanned. I wanted to know if theres anything out there that I could use to monitor the bandwidth of the networks, like individual VLANs and network as a whole. It doesnt matter if its a linux program or Windows. I can place it on a VM. I know you can use cacti for the firewall, if you can use this or something better can someone point it out for me? Thanks
