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。
