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
Ethernet Channel Bonding Driver: v3.6.0 (September 26, 2009) Bonding Mode: IEEE 802.3ad Dynamic link aggregation Transmit Hash Policy: layer2+3 (2) MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 802.3ad info LACP rate: fast Aggregator selection policy (ad_select): stable Active Aggregator Info: Aggregator ID: 1 Number of ports: 2 Actor Key: 17 Partner Key: 1073 Partner Mac Address: 3c:e8:24:e8:df:20 Slave Interface: eth1 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 80:18:44:e2:61:9d Aggregator ID: 1 Slave queue ID: 0 Slave Interface: eth2 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 80:18:44:e2:61:9e Aggregator ID: 1 Slave queue ID: 0
交换机的配置:
interface Eth-Trunk4 port link-type access port default vlan 301 mode lacp
