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