Dear Professionals,
I am using a Cisco Catalyst 6509. I have 3 VLAN's configured on it and the 6509 is responsible for the inter-VLAN routing.
I would like to find some way to be able to monitor the traffic on this switch. I am already monitoring (MRTG/RRDtool) the traffic on a per-port basis, but I would also like to get some details on which type of traffic is actually being generated. Ideally I would get the information which would be provided by netflow packets.
I understand that it will not be possible to obtain layer 3/4 information of traffic within the same VLAN. I am assuming that traffic which traverses 2 VLAN's is never switched and needs to be routed and thus processed by the switch. I am however failing to find a way to monitor this traffic.
Configuring an ip account on the ports doesn't seem to work. It is possible on the VLAN interfaces, but the traffic I am looking for doesn't seem to show up there.
Does anyone have any tips for me?
With kind regards,
Kevin
