Good day!
I have CRS125-24G-1S and Samsung MFU.
When I use ether9 for Samsung MFU I'l get an error: interface,warning eth10: bridge port received packet with own address as source address
(e4:8d:8c:6e:61:2a), probably loop
Ether10 up's automatically.

When I use ether10 for Samsung MFU Ether9 up's automatically, but no error.
ROS 6.38.1
Help. Can't use one port...
