Sounds good Kevin! This is a beautiful write-up, Mason. I'd agree that
those are important security considerations, and that the network
segmentation overall is worth doing.
I'd feel more confident your solution will solve the problem if we can
prove first that the latency experienced is being caused by aforementioned
ARP broadcast.
You mentioned the network may be experiencing a broadcast storm, this most
commonly happens when a switching loop exists somewhere in the circuit
(which Ethernet/IP I/O devices can inadvertently cause). Your document
confirms that RSTP (Rapid Spanning Tree Protocol) is disabled on all ports.
This protocol protects against Switching loops (which could very well be
the cause of this latency issue). RTSP creates a loop-free logical
topology, blocking redundant paths while allowing for rapid convergence.
Did you guys happen to do a wireshark scan while onsite?
This would give you the details on exactly what is going on (Packets
Dropped, ARP Consistency, Etc.)
Let me know your thoughts!
