Hello,
I have Traffic Flow enabled, and sent to a PC where I have Netflow traffic monitoring software.
I also enabled SNMP so I could read the interfaces, so on so forth.
I have used netflow on single ports in the past, however a bridge presents a new challenge.
The problem:
I can capture data from any port, as long as its not on a bridge. NOT if the port is on a bridge.
I can capture data from the bridge, however this is not relevant data.
I’ve tried:
Mirroring the port and capture the data on the mirrored port, however the mirroring was not successful, and I’m not sure if I did it correctly.
Messy things I can think of:
Give 2 ports an address, and use src-nats to redirect the traffic from one port to the other, and vice-versa, this however can cause some problems and I rather not do this.
Use a packet sniffer on the bridge, and then use the data to create graphs, connections, etc. Basically an alternate of using Netflow. But I’m really trying to get netflow to work on a bridge.
Any solutions/suggestions or help is very much appreciated.
Thank you,
