I could be wrong, but I don't think you get MAC addresses with netflow? I use netflow exclusively, but also have --no-mac set, so haven't really worried about.
Knowing what netflow was designed for, I doubt MAC addresses are even in the netflow records to begin with - but as mentioned, I could be wrong! I guess you could google for netflow record info or analyze a netflow packet and see if the MAC address is in there somewhere. ? - Why do you care about MAC's? I just get them from the switches bridging table or arp table when needed.

Everything else, except for the MAC issue, works great. I have verified that when running ntop on a physical local interface, MAC addresses do display. Likewise, when running ntop in place of the remote probe (on the remote box itself), MAC addresses also display. I've tried two different remote probes, and I've verified that ntop is not starting with the --no-mac option. Netflow plugin configuration: Interface address is set to the network I'm monitoring (10.3.0.0/255.255.0.0), flow aggregation is turned off, my local network is in the white list (10.3.0.0/16), nothing is in the black list. Also, I've tried using netflow v5 as well as v9 with the same result. I'm using version 3.2 of ntop. As the remote probe, I've used nprobe v5.0.0 and fprobe-ulog v1.1. Are there any recommended troubleshooting steps that I could take to see what's going on?
