Afficher la carte slave

(marche pas en LACP, normal...)

 # cat /sys/class/net/bond0/bonding/active_slave
 eth1

 # cat /sys/class/net/bond0/bonding/slaves
 eth0 eth1

Ajouter une carte du bonding

 # ifenslave -c bond0 eth0
 # echo +eth0 > /sys/class/net/bond0/bonding/slaves

Retirer une carte du bonding

 # ifenslave -d bond0 eth0
 # echo -eth0 > /sys/class/net/bond0/bonding/slaves

Module bonding

Le module bonding doit être chargé

 # lsmod | grep bond

Démarrer le bonding

 # /etc/init.d/network start
