L2 device mapping and monitoring
Hey all,
I'm looking for a tool to help map and monitor Layer 2 data flows for my OT application.
I deal with electrical substation networks and the protocols are heavily L2 oriented (most being multicast). Think IEC-61850, IEEE 1588 PTP, PRP, the usual substation stuff.
One issue we have is visibility over the links and visualizing the flow of data from one device to another to present it to the electrical engineers and technicians. This is very much unlike corporate networks with IP data flows.
I can do this by hand by looking up the LLDP neighbours for each bridge and ensuring the neighbour is indeed the one I expect, pull the ports statistics to get data rate and health and put it all in a nice drawing. But I haven't found a tool that would display this information graphically and in real-time and automatically.
This information is intended for substation techs so they can see at a glance on the SCADA link stats, ports status and act quickly and monitor trafic volume to see if it matches the expected values (trafic is predictable and constant). Their are not trained network engineers but they have received training for IEC-61850 which is network-heavy and Layer-2 based.
