Hi All,
Our Kernel Version is:- 4.14.40-g4796173fc5
we are using ethernet bonding driver with eth0 and eth1 interface and created bond0.
bond0 - 192.168.0.100
With balance-rr mode we are able to use 2 PHY ports simultaneously on same subnet with ethernet bonding.
But bitrate is very low while verify with iperf and packets also losing. below iperf report for you reference.
"Requirement is both ports needs to be accessed on same subnet simultaneously and speed also in Gbps or alteast Mbps".
we are looking for load balancing mode with some good speed in Mbps without packet drop, we have followed below document
Dual MAC Mode (Bonding) when we try to using balance-rr mode throughput is less and in other balance mode(Balance-xor,balance-tlb, balance-alb) we are not able to work make both ethernet port up.
is there any configuration is missing? we are using below commands
modprobe bonding
echo 0 > /sys/class/net/bond0/bonding/mode
echo 100 > /sys/class/net/bond0/bonding/miimon
ifconfig bond0 192.168.0.100 netmask 255.255.255.0 up
echo +eth0 > /sys/class/net/bond0/bonding/slaves
echo +eth1 > /sys/class/net/bond0/bonding/slaves
