I clone the repository BPI-R2-4.14 in ubuntu16.04 at R2,the image is the one upload at 2018.3, 2018-03-29-ubuntu-16.04-mate-desktop-bpi-r2-sd-emmc.img when using the origin kernel4.4, the wan port is working and able to get IP from DHCP but i install the kernel4.14 all ports doesn’t work ,even setting a static IP can’t get it work. I am wandering is there some modify job should be done to ubuntu’s network manager config file /etc/network/interface ? mine is empty . Command “dhclient -i eth1” doesn’t return. Sorry for my poor english. @frank-w
please show output of “uname-r;ip a”
you have to set eth0+eth1 first to up, then your wan/lanX you cannot run dhclient on ethX…it has to be run on wan/lanX
thanks , it worked after I execute “dhclient -i wan” .
"ip a "shows lan0@eth0 …something like that, ubuntu’s network manager seems don’t compatible with the switch driver…
kernel version is 4.14.95 ifconfig shows eth0 and eth1
Imho ifconfig (old tool) shows only interfaces which are up (without -a switch).
Ip a shows also dsa-user-ports (lanx,wan) with cpu-port relationship (@ethx).
I don’t know how to configure network-manager,but you need to set first ethx to up (without ip-config) and then configure user-ports (lanx,wan)
