双网卡绑定linux7.2 CentOS 7.2 bond实现网卡聚合链路(双网卡绑定)脚本及验证(适合云平台)...

使用bond实现网卡聚合链路脚本:

#!/bin/bash

#创建一个名为bond0的链路接口

验证：

1.查看bond0状态：

[root@localhost~]#cat/proc/net/bonding/bond0

EthernetChannelBondingDriver:v3.7.1(April27,)

BondingMode:fault-tolerance(active-backup)

PrimarySlave:None

CurrentlyActiveSlave:eno2#当前主接口

MIIStatus:up

MIIPollingInterval(ms):100

UpDelay(ms):0

DownDelay(ms):0

SlaveInterface:eno2

MIIStatus:up

Speed:1000Mbps

Duplex:full

LinkFailureCount:0

PermanentHWaddr:2c:76:8a:51:d2:09

SlavequeueID:0

SlaveInterface:eno1

MIIStatus:up

Speed:1000Mbps

Duplex:full

LinkFailureCount:0

PermanentHWaddr:2c:76:8a:51:d2:08

SlavequeueID:0

[root@localhost~]#cat/proc/net/bonding/bond0

EthernetChannelBondingDriver:v3.7.1(April27,)

BondingMode:fault-tolerance(active-backup)

PrimarySlave:None

CurrentlyActiveSlave:eno2#当前主接口

MIIStatus:up

MIIPollingInterval(ms):100

UpDelay(ms):0

DownDelay(ms):0

SlaveInterface:eno2

MIIStatus:up

Speed:1000Mbps

Duplex:full

LinkFailureCount:0

PermanentHWaddr:2c:76:8a:51:d2:09

SlavequeueID:0

SlaveInterface:eno1

MIIStatus:up

Speed:1000Mbps

Duplex:full

LinkFailureCount:0

PermanentHWaddr:2c:76:8a:51:d2:08

SlavequeueID:0

2.测试，宕掉当前主接口，看是否切换

[root@localhost~]#ifdowneno2

Device'eno2'successfullydisconnected.

[root@localhost~]#cat/proc/net/bonding/bond0

EthernetChannelBondingDriver:v3.7.1(April27,)

BondingMode:fault-tolerance(active-backup)

PrimarySlave:None

CurrentlyActiveSlave:eno1#切换成功

MIIStatus:up

MIIPollingInterval(ms):100

UpDelay(ms):0

DownDelay(ms):0

SlaveInterface:eno1

MIIStatus:up

Speed:1000Mbps

Duplex:full

LinkFailureCount:0

PermanentHWaddr:2c:76:8a:51:d2:08

SlavequeueID:0

[root@localhost~]#ifdowneno2

Device'eno2'successfullydisconnected.

[root@localhost~]#cat/proc/net/bonding/bond0

EthernetChannelBondingDriver:v3.7.1(April27,)

BondingMode:fault-tolerance(active-backup)

PrimarySlave:None

CurrentlyActiveSlave:eno1#切换成功

MIIStatus:up

MIIPollingInterval(ms):100

UpDelay(ms):0

DownDelay(ms):0

SlaveInterface:eno1

MIIStatus:up

Speed:1000Mbps

Duplex:full

LinkFailureCount:0
