Bonding NIC

Menggabungkan 2 atau lebih NIC ke 1 Ip address
Buat config Bond0 sbb :# cat /etc/sysconfig/network-scripts/ifcfg-bond0



DEVICE=bond0
IPADDR=192.168.1.12
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
USERCTL=no
BOOTPROTO=none
ONBOOT=yes

Ubah config Eth0, Eth1 dan Eth2 sbb :
# cat /etc/sysconfig/network-scripts/ifcfg-eth0

# Linksys Gigabit Network Adapter
DEVICE=eth0
BOOTPROTO=none
#HWADDR=00:12:17:5C:A7:9D

#NETMASK=255.255.255.0
#TYPE=Ethernet
#GATEWAY=192.168.1.1
#USERCTL=no
#IPV6INIT=no
#PEERDNS=yes
ONBOOT=yes
# Settings for Bond
MASTER=bond0

# cat /etc/sysconfig/network-scripts/ifcfg-eth1

# Linksys Gigabit Network Adapter
DEVICE=eth1
BOOTPROTO=none
