链路聚合实训报告总结（链路聚合实验配置）

一、实验拓扑

二、实验配置命令

1、手工负载分担模式

SW1上的配置

<Huawei>system-view

[Huawei]sysname SW1

[SW1]interface eth-trunk 1 //创建eth-trunk 1

[SW1-Eth-Trunk1]mode manual load-balance

//配置eth-trunk工作模式为手工负载分担模式

[SW1-Eth-Trunk1]load-balance src-dst-mac

//配置负载分担方式为源目MAC地址

[SW1-Eth-Trunk1]trunkport e0/0/1 //将1号端口加入到eth-trunk 1中

[SW1-Eth-Trunk1]trunkport e0/0/2 //将2号端口加入到eth-trunk 1中

[SW1-Eth-Trunk1]trunkport e0/0/3 //将3号端口加入到eth-trunk 1中

[SW1-Eth-Trunk1]display eth-trunk 1

Eth-Trunk1's state information is:

WorkingMode: NORMAL Hash arithmetic: According to SA-XOR-DA

Least Active-linknumber: 1 Max Bandwidth-affected-linknumber: 8

Operate status: up Number Of Up Port In Trunk: 3

--------------------------------------------------------------------------------

PortName Status Weight

Ethernet0/0/1 Up 1

Ethernet0/0/2 Up 1

Ethernet0/0/3 Up 1

SW2上的配置

<Huawei>system-view

[Huawei]sysname SW2

[SW2]interface eth-trunk 1

[SW2-Eth-Trunk1]mode manual load-balance

[SW2-Eth-Trunk1]load-balance src-dst-mac

[SW2-Eth-Trunk1]trunkport e0/0/1

[SW2-Eth-Trunk1]trunkport e0/0/2

[SW2-Eth-Trunk1]trunkport e0/0/3

[SW2-Eth-Trunk1]display eth-trunk 1

2、lacp模式（LACP模式需要有链路聚合控制协议LACP的参与）

SW1上的配置

[SW1]interface eth-trunk 1

[SW1-Eth-Trunk1]mode lacp-static

//配置eth-trunk工作模式为LACP模式

[SW1-Eth-Trunk1]load-balance src-dst-ip

//配置负载分担方式为源目IP地址（默认的方式）

[SW1-Eth-Trunk1]trunkport e0/0/1

[SW1-Eth-Trunk1]trunkport e0/0/2

[SW1-Eth-Trunk1]trunkport e0/0/3

[SW1-Eth-Trunk1]display eth-trunk 1

SW2上的配置

[SW2]interface eth-trunk 1

[SW2-Eth-Trunk1]mode lacp-static

[SW2-Eth-Trunk1]load-balance src-dst-ip

[SW2-Eth-Trunk1]trunkport e0/0/1

[SW2-Eth-Trunk1]trunkport e0/0/2

[SW2-Eth-Trunk1]trunkport e0/0/3

[SW2-Eth-Trunk1]display eth-trunk 1

Eth-Trunk1's state information is:

Local:

LAG ID: 1 WorkingMode: STATIC

Preempt Delay: Disabled Hash arithmetic: According to SIP-XOR-DIP

System Priority: 32768 System ID: 4c1f-cc61-7567

Least Active-linknumber: 1 Max Active-linknumber: 8

Operate status: up Number Of Up Port In Trunk: 3

Ethernet0/0/3 32768 4c1f-cc50-2fef 32768 4 289 10111100

3、在LACP模式下修改最大活跃链路数

[SW1]interface eth-trunk 1

[SW1-Eth-Trunk1]max active-linknumber 2 //配置最大活跃链路为2条

[SW2]interface eth-trunk 1

[SW2-Eth-Trunk1]max active-linknumber 2 //配置最大活跃链路为2条

[SW1]display eth-trunk 1

--------------------------------------------------------------------------------

ActorPortName Status PortType PortPri PortNo PortKey PortState Weight

Ethernet0/0/1 Selected 100M 32768 2 289 10111100 1

Ethernet0/0/2 Selected 100M 32768 3 289 10111100 1

Ethernet0/0/3 Unselect 100M 32768 4 289 10100000 1

4、在SW1上将1号端口关闭，模拟链路故障，再次查看eth-trunk 1信息。

[SW1]inter e0/0/1

[SW1-Ethernet0/0/1]shutdown

[SW1-Ethernet0/0/1]quit

[SW1]display eth-trunk 1

Ethernet0/0/1 Unselect 100M 32768 2 289 10100010 1

Ethernet0/0/2 Selected 100M 32768 3 289 10111100 1

Ethernet0/0/3 Selected 100M 32768 4 289 10111100 1
