I was told that port 2 is optimized for local traffic.
We have the bottom port going to our local network switch inside our cabinet.
We do not use the top port at all. If we need something to go back to the plants network, we do this inside our main electrical cabinet. Via a managed switch, or a NAT switch.
We have had issues in the past with traffic on the robot's network and freezing the teach pendant and/or faulting the robot with a bunch of weird errors.

We had a major problem with this a little while back. We accidentally fixed the issue at the same time as swapping main boards twice, then on the third time, we swapped the main board without making the mistake that fixed it and called Fanuc when it didn't work.
Long story short, we had too much Ethernet traffic and it was locking up two robots. The answer was to unplug the ethernet from both, cycle power, then re-plug the ethernet. So we replaced two Main Boards for no reason, and just happened to have cycled power without Ethernet which was the real fix.
We have a group of (4) robots that use port 1 for local communication, port 2 is connected to plant network. Perhaps that's why we get the occasional "Host-244 Ethernet Throttle" message. These haven't run for awhile, so they're locked up.
here is what Fanuc says to that:
Either one or both Ethernet ports can be configured for use with EtherNet/IP. Note that in order to use
both ports at the same time they must be properly configured on separate subnets. Also note that port 2
(CD38B) is optimized for Ethernet I/O protocols such as EtherNet/IP. The preferred setup is to connect port 1 (CD38A) to your building network to access the robot through HTTP, FTP, and so forth , and to
connect port 2 (CD38B) to an isolated network for use by EtherNet/IP.
here is what Fanuc says to that:
Where did you get this info, I'd appreciate if I'd tell me please.
On a related note, I've recently been having problems with the ethernet ports on brand-new R30ib+ controllers (core version 9.3). Long story short, Port 1 (under Host Comms) will not accept HTTP or FTP connections -- it doesn't timeout, but returns "connection refused". But Port 1 pings fine.
Port 2, on the other hand, works fine with HTTP, so I've been forced to use that for irVision and irPickTool setups. But this concerns me a bit, as it conflicts directly with bidzej's post. I've also never had this problem before -- every R30 always seemed happy to accept HTTP, FTP, and Telnet on any port.
There were no settings for the ports in Host Comm, since these robots were all fresh out of the crate from Fanuc. The only thing I did was add the IP and Netmask for both ports.

I just found it in manual MAROU91EN02171E Rev C, which is a V9.30 Ethernet/IP Communications manual. It was in section 2.3.
The text is exactly the same as bidzej's post.
