I configured netflow on a cat6k with ntop as a datacollector. As the source I cfg a vlan interface
================== cat 6500
interface Vlanxxx ! ip flow-export ingress ip route-cache flow ! ip address x.x.x.x 255.255.255.192 no ip redirects no ip proxy-arp end
ip flow-export source vlan xxx ip flow-export destination x.x.x.x 2055 ==================================
right now i should collect _all_ traffic on the backplane is this possible with ntop or should I use for MRTG ...maybe any other freeware tool ??
