iMac Pro incorrect port negotiation with Cisco RV340

[HDFan]

I am testing a Cisco RV340 small business router/firewall with my iMac Pro and have found that it does not do proper port negotiation. I am limited to 100 Mbps (here on port 4):

I know that the cat 7 cable and and port work just fine as:

1. I get the ~1000Mbps supported by my Xfinity modem when connected directly to a 10 Gbps switch

2. I have seen over 1 Gbps when doing file transfers over the network

3. Switching the devices on ports 1 & 4 also switches the negotiated speed rates

I have tried manually changing the port specifications in Network Preferences/Advanced/Hardware but it makes no difference.

Cisco is working the issue but I wanted to see if there is anything else I could do on the iMac end.

Just received a response from Cisco. The RV340 will not negotiate a 10 Gbps connection with an iMac Pro. Asked them to file a feature request.

That seems really odd. Which device is not up to standards? Maybe putting a 3rd party 10Gps switch between them would work for now?

Don't know whether the problems is on the Cisco or the Apple end. Since they indicated that they would need to change their firmware rather than pointing their finger at Apple I am sort of assuming it's their problem.

Yes, that is what I'm doing. My iMac Pro is connected to a QNAP 10 Gbps switch. The RV340 is between the QNAP and the cable modem. with the switch running off the RV340. modem > RV340 > QNAP switch > devices
