你是公司的网络管理员。现在公司购买了两台华为的S5700系列交换机，需要进行调试。现在决定对双工和速度方面进行技术测试。
学习任务
步骤一.以太网交换机基本操作
华为交换机接口默认设置为自动协商速率和双工模式，在本任务中，我们将S1和S2的G0/0/9和G0/0/10接口的速率和双工改为手动设置模式。
更改系统名称，查看S1G0/0/9和G0/0/10接口详细信息。[Huawei]sysname S1

将S1的G0/0/9和G0/0/10接口设置为100M速率和全双工模式。

更改接口的速率和双工模式之前应先关闭接口的走动协商功能。
将S2的G0/0/9和G0/0/10接口设置为100M速率和全双工模式。

步骤二.配置手动链路聚合。
在S1、S2上创建Eth-trunk 1.清楚S1和S2的G0/0/9和G0/0/10接口上的默认配置后将其加入Eth-trunk 1.
[S1]interfaceEth-trunk 1
[S1-Eth-Trunk1]q
[S1]interfacegi0/0/9
[S1-GigabitEthernet0/0/9]eth-trunk1
[S1-GigabitEthernet0/0/9]interfacegi0/0/10
[S1-GigabitEthernet0/0/10]eth-trunk1
[S1-GigabitEthernet0/0/10]q

[S2]interfaceEth-trunk 1
[S2-Eth-Trunk1]q
[S2]interfacegi0/0/9
[S2-GigabitEthernet0/0/9]eth-trunk1
[S2-GigabitEthernet0/0/9]interfacegi0/0/10
[S2-GigabitEthernet0/0/10]eth-trunk1
[S2-GigabitEthernet0/0/10]q
Eth-trunk配置结果验证。
[S1]displayeth-trunk 1
Eth-Trunk1's stateinformation is:
WorkingMode:NORMAL Hash arithmetic: Accordingto SIP-XOR-DIP
LeastActive-linknumber: 1 MaxBandwidth-affected-linknumber: 8
Operatestatus: up Number Of Up Port InTrunk: 2
--------------------------------------------------------------------------------
PortName Status Weight
GigabitEthernet0/0/9 Up 1
GigabitEthernet0/0/10 Up 1

[S1]

[S2]displayeth-trunk 1
Eth-Trunk1's stateinformation is:
WorkingMode:NORMAL Hash arithmetic: Accordingto SIP-XOR-DIP
Least Active-linknumber:1 Max Bandwidth-affected-linknumber:8
Operatestatus: up Number Of Up Port InTrunk: 2
--------------------------------------------------------------------------------
PortName Status Weight
GigabitEthernet0/0/9 Up 1
GigabitEthernet0/0/10 Up 1
由以上可以看出，配置eth-trunk处于正常工作状态。
