Depends.  A lot of layer two stuff is in the code.

If you want to make the appropriate code change, the best model is probably
VLAN (which is also a fixed length header at layer 2).  That discussion
belongs on ntop-dev.

Subject: [Ntop] Packet Format Question

I would like to use ntop to characterize data on a private government
network.

The format of the protocol stack is somewhat proprietary, although it is
being run on an Ethernet network with IP.

The catch is that a proprietary "shim" header is present between the
Ethernet and IP headers (kind of like MPLS, but proprietary).

Will ntop report the network traffic as "Ethernet - Unknown / Other" or does
it search for the IP Header independent of the Ethernet Next Protocol field?

Thanks,
Barry
