配置LACP模式的链路聚合

1、在SwitchA上创建链路聚合RTH-Trunk1 并配置LACP模式。SwitchB与A相同。

<SwitchA>sys

[SwitchA]interface eth-trunk 1

[SwitchA-Eth-Trunk1]mode lacp

[SwitchA-Eth-Trunk1]quit

[SwitchA]

2、配置SwitchA中的端口加入eth-trunk 1，SwicthB类似。

[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

3、在SwitchA上配置优先等级为100，使其成为主动端。      在 SwitchA 上配置活动接口上限阈值为2

[SwitchA] lacp priority 100 //配置 switchA 的 lacp 优先级为100[SwitchA] interface eth-trunk 1

[SwitchA-Eth-Trunk1] max active-linknumber 2 //配置最大活动接口数为2[SwitchA-Eth-Trunk1] quit

4、在SwitchA上配置接口优先等级确定活动链路。

[SwitchA] interface gigabitethernet 0/0/1

[SwitchA-GigabitEthernet0/0/1] lacp priority 100

                                                  //配置接口 lacp 优先级为100

[SwitchA-GigabitEthernet0/0/1] quit

[SwitchA] interface gigabitethernet 0/0/2

[SwitchA-GigabitEthernet0/0/2] lacp priority 100

[SwitchA-GigabitEthernet0/0/2] quit
