操作步骤
步骤
1
在
SwitchA
上创建
Eth-Trunk1
并配置为
LACP
模式。
SwitchB
的配置与
SwitchA
类似，不
再赘述

[HUAWEI]
sysname SwitchA
[SwitchA]
interface eth-trunk 1
[SwitchA-Eth-Trunk1]
mode lacp
[SwitchA-Eth-Trunk1]
quit
步骤
2
配置
SwitchA
上的成员接口加入
Eth-Trunk
。
SwitchB
的配置与
SwitchA
类似，不再赘述
[SwitchA]
interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1]
eth-trunk 1
[SwitchA-GigabitEthernet0/0/1]
quit
[SwitchA]
interface gigabitethernet 0/0/2
[SwitchA-GigabitEthernet0/0/2]
eth-trunk 1
[SwitchA-GigabitEthernet0/0/2]
quit
[SwitchA]
interface gigabitethernet 0/0/3
[SwitchA-GigabitEthernet0/0/3]
eth-trunk 1
[SwitchA-GigabitEthernet0/0/3]
quit
步骤
3
在
SwitchA
上配置系统优先级为
100
，使其成为
LACP
主动端
[SwitchA]
lacp priority 100
步骤
4
在
SwitchA
上配置活动接口上限阈值为
2
[SwitchA]
interface eth-trunk 1
[SwitchA-Eth-Trunk1]
max active-linknumber 2
[SwitchA-Eth-Trunk1]
quit
步骤
5
在
SwitchA
上配置接口优先级确定活动链路
[SwitchA]
interface gigabitethernet 0/0/1
[SwitchA-GigabitEthernet0/0/1]
lacp priority 100
[SwitchA-GigabitEthernet0/0/1]
quit
[SwitchA]
interface gigabitethernet 0/0/2
[SwitchA-GigabitEthernet0/0/2]
lacp priority 100
[SwitchA-GigabitEthernet0/0/2]
quit
步骤
6
创建
VLAN
并将接口加入
VLAN
。
#
创建
VLAN10
和
VLAN20
并分别加入接口。
SwitchB
的配置与
SwitchA
类似，不再赘
述。
[SwitchA]
vlan batch 10 20
[SwitchA]
interface gigabitethernet 0/0/4
[SwitchA-GigabitEthernet0/0/4]
port link-type trunk
[SwitchA-GigabitEthernet0/0/4]
port trunk allow-pass vlan 10
[SwitchA-GigabitEthernet0/0/4]
quit
[SwitchA]
interface gigabitethernet 0/0/5
[SwitchA-GigabitEthernet0/0/5]
port link-type trunk
[SwitchA-GigabitEthernet0/0/5]
port trunk allow-pass vlan 20
[SwitchA-GigabitEthernet0/0/5]
quit
#
配置
Eth-Trunk1
接口允许
VLAN10
和
VLAN20
通过。
SwitchB
的配置与
SwitchA
类似，
不再赘述。
[SwitchA]
interface eth-trunk 1
[SwitchA-Eth-Trunk1]
port link-type trunk
[SwitchA-Eth-Trunk1]
port trunk allow-pass vlan 10 20
[SwitchA-Eth-Trunk1]
quit
步骤
7
验证配置结果
#
查看各
Switch
设备的
Eth-Trunk
信息，查看链路是否协商成功。

通过以上显示信息可以看到，
SwitchA
的系统优先级为
100
，高于
SwitchB
的系统优先级。Eth-Trunk
的成员接口中
GigabitEthernet0/0/1
、
GigabitEthernet0/0/2
成为活动接口，处于“Selected
”状态，接口
GigabitEthernet0/0/3
处于“
Unselect
”状态，同时实现M
条链路的负载分担和
N
条链路的冗余备份功能。
