聚合模式需要一致
3 LACP链路聚合对接操作指导
3.1 与思科设备对接操作指导
3.1.1 互通性分析
表7 互通性分析
H3C | Cisco | 互通结论 |
Static（缺省） | On（缺省） | 可以互通 |
Dynamic | Active | 可以互通 |
3.1.2 采用静态聚合模式对接案例
1. 组网需求
如图10所示，H3C设备与Cisco设备通过各自的二层以太网接口相互连接。现要求在H3C设备和Cisco设备上分别配置静态链路聚合，实现增加链路带宽、提高链路可靠性的目的。
2. 配置步骤
· 配置H3C设备
# 创建三层聚合接口1，并为该接口配置IP地址和子网掩码。
<H3C> system-view
[H3C] interface Route-aggregation 1
[H3C-Route-Aggregation1] ip address 16.1.105.33 24
[H3C-Route-Aggregation1] quit
# 将三层以太网接口GigabitEthernet1/0/1加入三层聚合组1中。
[H3C] interface gigabitethernet 1/0/1
[H3C-GigabitEthernet1/0/1] port link-aggregation group 1
[H3C-GigabitEthernet1/0/1] quit
# 将三层以太网接口GigabitEthernet1/0/2加入三层聚合组1中。
[H3C] interface GigabitEthernet 1/0/2
[H3C-GigabitEthernet1/0/2] port link-aggregation group 1
[H3C-GigabitEthernet1/0/2] quit

要将思科交换机与华三交换机进行二层链路聚合（LACP），你需要在华三交换机上进行以下配置：
-
进入系统视图：
<H3C> system-view -
创建聚合接口：
[H3C] interface Bridge-Aggregation 1 -
将物理接口加入聚合组：
[H3C-Bridge-Aggregation1] port link-aggregation group 1 [H3C-Bridge-Aggregation1] quit -
配置物理接口：
[H3C] interface GigabitEthernet 1/0/1 [H3C-GigabitEthernet1/0/1] port link-aggregation group 1 [H3C-GigabitEthernet1/0/1] quit [H3C] interface GigabitEthernet 1/0/2 [H3C-GigabitEthernet1/0/2] port link-aggregation group 1 [H3C-GigabitEthernet1/0/2] quit -
配置聚合接口为Trunk模式（如果需要）：
[H3C] interface Bridge-Aggregation 1 [H3C-Bridge-Aggregation1] port link-type trunk [H3C-Bridge-Aggregation1] port trunk permit vlan all [H3C-Bridge-Aggregation1] quit -
启用LACP：
[H3C] interface Bridge-Aggregation 1 [H3C-Bridge-Aggregation1] link-aggregation mode dynamic [H3C-Bridge-Aggregation1] quit
这些步骤将确保华三交换机的端口正确配置为与思科交换机进行二层链路聚合12。
