This document discusses three ways to configure Linux bonding in the kernel: 1) Using modprobe and alias commands, 2) Using sysfs directly by writing to bonding_masters and mode files, and 3) Adding slaves to an interface using sysfs without ifenslave. It notes the benefits of the sysfs method are handling multiple interfaces, reconfiguring without reboot, and avoiding problems with modprobe.

1. Linux bonding meets sysfs
(sau ce te faci cand CONFIG_BONDING=y)

2. The usual way
● modprobe bonding mode=1 miimon=100
● alias bond0 bonding
options bond0 mode=active-failover miimon=100

3. The “OMG it's buit in!” way
echo “ +bond0” > /sys/class/net/bonding_masters
echo "active-backup" >
/sys/class/net/bond0/bonding/mode
echo “ 100” > /sys/class/net/bond0/bonding/mode

4. The “let's pretend we don't have
ifenslave” bonus slide
ifconfig bond0 up
echo “ +eth0” >
/sys/class/net/bond0/bonding/slaves
echo “ +eth1” >
/sys/class/net/bond0/bonding/slaves

5. But why?
● Interfete multiple
● Reconfigurari fara reboot
● Probleme la modprobe -o bond0
● Distributii fara scripturi gata facute ;)
