This is a easy way to manage your bondings through the sysfs interface.
Load the bond module:
# modprobe bond
Create a new bonding bond0:
echo "+bond0" > /sys/class/net/bonding_masters
View the existing bondings:
# cat /sys/class/net/bonding_masters bond0 bond1
Add interfaces to bond0 bonding:
echo "+eth0" > /sys/class/net/bond0/bonding/slaves echo "+eth1" > /sys/class/net/bond0/bonding/slaves
Remove an interface from an existing bonding
echo "-eth0" > /sys/class/net/bond0/bonding/slaves
Remove the bond0 inteface
echo "-bond0" > /sys/class/net/bonding_masters
Change the bonding mode (The bond interface must be down before the mode can be changed.):
echo balance-alb > /sys/class/net/bond0/bonding/mode
or
echo 6 > /sys/class/net/bond0/bonding/mode
A full example:
# modprobe bonding # modprobe e100 # echo balance-alb > /sys/class/net/bond0/bonding/mode # ifconfig bond0 192.168.1.1 netmask 255.255.255.0 up # echo 100 > /sys/class/net/bond0/bonding/miimon # echo +eth0 > /sys/class/net/bond0/bonding/slaves # echo +eth1 > /sys/class/net/bond0/bonding/slaves
