CentOS 6 / RHEL 6配置bonding 4模式

实现bond 802.3ad or 4 模式:(IEEE 802.3ad)，

    方式:创建一个整合的组，这个组会共享网速和网络双工（duplex）设置。模式 4 会根据 IEEE 802.3ad 标准使用活动组中的所有网络接口

    1、需要交换机配合配置,

   2、两端负载均衡模式:基于源IP和目的IP

 

系统配置:

  

/etc/modprobe.d/bonding.conf 

alias bond1 bonding
options bond1 mode=4 miimon=100 lacp_rate=fast xmit_hash_policy=layer2+3



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

DEVICE=eth1
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
MASTER=bond1
SLAVE=yes


/etc/sysconfig/network-scripts/ifcfg-eth2

DEVICE=eth2
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
MASTER=bond1
SLAVE=yes


/etc/sysconfig/network-scripts/ifcfg-bond1 

DEVICE=bond1
IPADDR=IP地址
NETMASK=子网掩码
BROADCAST=广播地址
GATEWAY=网关
ONBOOT=yes
BOOTPROTO=static
USERCTL=no
TYPE=Ethernet

 

检查配置:

cat /proc/net/bonding/bond1
