2. Project Requirements

Customer Requirements Linuxthe system server dual NIC is connected to two units 7706 core Switchdo The NIC's bond take active-backupMode, improve the linkfault-tolerant capability.

3. Configuration Steps

1,, Create bond0 Configuration file

V I /etc/sysconfig/network-scripts/ifcfg-bond0

Device=bond0

Type=bond

ipaddr=6.0.20.6

netmask=255.255.255.0

network=6.0.20.0

broadcast=6.0.20.255

gateway=6.0.20.1

Onboot=yes

Bootproto=none

Userctl=no

2 , Modify the bound eth0 and eth1 . configuration file

V I /etc/sysconfig/network-scripts/ifcfg-eth0

Device=eth0

Userctl=no

Onboot=yes

Master=bond0

Slave=yes

Bootproto=none

V I /etc/sysconfig/network-scripts/ifcfg-eth1

Device=eth1

Userctl=no

Onboot=yes

Master=bond0

Slave=yes

Bootproto=none

3. Loading Bond Module Drive

Vi/etc/modprobe.d/bond0.conf

Alias Bond0 Bonding

Options Bond0 miimon=100 mode=1

4./etc/rc.d/rc.local setting Boot from boot

I Fen slave bond0 eth0 eth1
