Конфигурируем сетевые интерфейсы:
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
SLAVE=yes
MASTER=bond0
USERCTL=no
# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
SLAVE=yes
MASTER=bond0
USERCTL=no
# cat /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
BOOTPROTO=none
IPADDR=172.17.44.52
NETMASK=255.255.255.240
NETWORK=172.17.44.48
GATEWAY=172.17.44.49
ONBOOT=yes
USERCTL=no
Загружаем модуль и перегружаем сеть:
# grep "bond" /etc/modprobe.conf
alias bond0 bonding
options bond0 mode=1 miimon=100
# service network restart
Смотрим, что у нас получилось:
# cat /proc/net/bonding/bond0
