华三交换机配置端口聚合之二层端口聚合

工作中常会遇到交换机配置端口聚合的场景，可以起到增加带宽和可靠性的要求。端口聚合可分为二层聚合和三层聚合，以及静态和动态聚合，下面主要介绍二层端口的静态和动态聚合配置。

拓扑如图，swa和swb各自的1，2，3，都加入到聚合口中。4，5口下联pc等终端。

一，二层端口静态聚合

配置SWA

配置SWA下联的vlan和接口，

分别把GE1/0/4和GE1/0/5加入vlan40和vlan50 [SWA]vlan 40 [SWA-vlan40]port GigabitEthernet 1/0/4 [SWA]vlan 50 [SWA-vlan50]port GigabitEthernet 1/0/5

创建二层聚合口1

[SWA]interface Bridge-Aggregation 1 //创建聚合组1

分别把GE1/0/1,GE1/0/2,GE1/0/3加入到聚合组1 [SWA]interface GigabitEthernet 1/0/1 [SWA-GigabitEthernet1/0/1]port link-aggregation 1 [SWA]interface GigabitEthernet 1/0/2 [SWA-GigabitEthernet1/0/2]port link-aggregation group 1 [SWA]interface GigabitEthernet 1/0/3 [SWA-GigabitEthernet1/0/3]port link-aggregation group 1

配置二层聚合接口1为Trunk端口，并允许VLAN 40和50的报文通过。 [SWA]interface Bridge-Aggregation 1 [SWA-Bridge-Aggregation1]port link-type trunk [SWA-Bridge-Aggregation1]port trunk permit vlan 40 50

配置SWB

创建vlan40和vlan50，并分别把GE1/0/4和GE1/0/5加入到vlan40，vlan50 [SWB]vlan 40 [SWB-vlan40]port GigabitEthernet 1/0/4

[SWB]vlan 50 [SWB-vlan50]port GigabitEthernet 1/0/5

创建二层聚合口1 [SWB]interface Bridge-Aggregation 1 //创建聚合组1 [SWB-Bridge-Aggregation1]qu

分别把GE1/0/1,GE1/0/1,GE1/0/1加入到聚合组1

[SWB]interface GigabitEthernet 1/0/1 [SWB-GigabitEthernet1/0/1]port link-aggregation group 1 [SWB]interface GigabitEthernet 1/0/2 [SWB-GigabitEthernet1/0/2]port link-aggregation group 1 [SWB]interface GigabitEthernet 1/0/3 [SWB-GigabitEthernet1/0/3]port link-aggregation group 1

配置二层聚合接口1为Trunk端口，并允许VLAN 40和50的报文通过。

[SWB]interface Bridge-Aggregation 1 [SWB-Bridge-Aggregation1]port link-type trunk [SWB-Bridge-Aggregation1]port trunk permit vlan 40 50

使用命令display link-aggregation verbose查看聚合组的详细信息。

二，二层端口动态聚合配置

拓扑和上面配置静态时一样

配置SWA 创建vlan40，vlan50分别把GE1/0/4和GE1/0/5加入vlan40和vlan50

[SWA]interface Bridge-Aggregation 1 //创建聚合组1 [SWA-Bridge-Aggregation1]link-aggregation mode dynamic //聚合为动态模式

分别把GE1/0/1,GE1/0/1,GE1/0/1加入到聚合组1 [SWA]interface GigabitEthernet 1/0/1 [SWA-GigabitEthernet1/0/1]port link-aggregation 1 [SWA]interface GigabitEthernet 1/0/2 [SWA-GigabitEthernet1/0/2]port link-aggregation group 1 [SWA]interface GigabitEthernet 1/0/3 [SWA-GigabitEthernet1/0/3]port link-aggregation group 1

配置二层聚合接口1为Trunk端口，并允许VLAN 40和50的报文通过。

[SWA]interface Bridge-Aggregation 1 [SWA-Bridge-Aggregation1]port link-type trunk [SWA-Bridge-Aggregation1]port trunk permit vlan 40 50

SWB

[SWB]vlan 40 [SWB-vlan40]port GigabitEthernet 1/0/4 [SWB]vlan 50 [SWB-vlan50]port GigabitEthernet 1/0/5

[SWB]interface Bridge-Aggregation 1 [SWB-Bridge-Aggregation1]link-aggregation mode dynamic

分别把GE1/0/1,GE1/0/1,GE1/0/1加入到聚合组1

[SWB]interface GigabitEthernet 1/0/1 [SWB-GigabitEthernet1/0/1]port link-aggregation group 1 [SWB]interface GigabitEthernet 1/0/2 [SWB-GigabitEthernet1/0/2]port link-aggregation group 1 [SWB]interface GigabitEthernet 1/0/3 [SWB-GigabitEthernet1/0/3]port link-aggregation group 1

配置二层聚合接口1为Trunk端口，并允许VLAN 40和50的报文通过。

[SWB]interface Bridge-Aggregation 1 [SWB-Bridge-Aggregation1]port link-type trunk [SWB-Bridge-Aggregation1]port trunk permit vlan 40 50

在SWA上使用display link-aggregation verbose查看聚合组的信息。
