Bonding eth interfaces on iMX6sx sabre-sdb board

I got 6sx sabre-sdb board. Distribution is build using Yocto project as defined in BSP documentation (fsl-yocto-L3.14.38_6ul-ga.tar.gz).


I’m trying  to bond eth0 and eth1 interfaces in active-backup mode.

Kernel (3.14.38) has been reconfigured to include bonding driver.

Driver is operational and can be shaped through /sys/class/net/bond0/bonding/.

But, when I’m manually enslave eth0 or eth1 interface using ifenslave, board hungs.

Following are the steps I’m using to initialize bond0 interface.


root@imx6sxsabresd:~# echo 1 > /sys/class/net/bond0/bonding/mode
root@imx6sxsabresd:~# ifconfig bond0
IPv6: ADDRCONF(NETDEV_UP): bond0: link is not ready
8021q: adding VLAN 0 to HW filter on device bond0
root@imx6sxsabresd:~# echo 100 > /sys/class/net/bond0/bonding/miimon
bonding: bond0: Setting MII monitoring interval to 100.
root@imx6sxsabresd:~# ifenslave -f -v bond0 eth1
ifenslave.c:v1.1.0 (December 1, 2                           


At this point board is dead.


Also, I have tried to achieve same through configuring bond0 in /etc/network/interfaces.

Adding following will create bond0, but fail to enslave eth0 and eth1 (board is alive).


auto bond0

iface bond0 inet dhcp

                    bond-slaves eth0 eth1

                    bond-mode active-backup

                    bond-miimon 100

                    bond-primary eth0 eth1




Have anyone got eth0 and eth1 interfaces working in active-backup mode using bonding or team drivers?

Is there some obvious step(s) I have missed?


Any help is much appreciated .
