華三交換機配置端口聚合之二層端口聚合

工作中常會遇到交換機配置端口聚合的場景，可以起到增加帶寬和可靠性的要求。端口聚合可分為二層聚合和三層聚合，以及靜态和動态聚合，下面主要介紹二層端口的靜态和動态聚合配置。

拓撲如圖，swa和swb各自的1，2，3，都加入到聚合口中。4，5口下聯pc等終端。

一，二層端口靜态聚合

配置SWA

配置SWA下聯的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

創建二層聚合口1

[SWA]interface Bridge-Aggregation 1 //創建聚合組1

分别把GE1/0/1,GE1/0/2,GE1/0/3加入到聚合組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

配置二層聚合接口1為Trunk端口，并允許VLAN 40和50的報文通過。

[SWA]interface Bridge-Aggregation 1

[SWA-Bridge-Aggregation1]port link-type trunk

[SWA-Bridge-Aggregation1]port trunk permit vlan 40 50

配置SWB

創建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

創建二層聚合口1

[SWB]interface Bridge-Aggregation 1 //創建聚合組1

[SWB-Bridge-Aggregation1]qu

分别把GE1/0/1,GE1/0/1,GE1/0/1加入到聚合組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

配置二層聚合接口1為Trunk端口，并允許VLAN 40和50的報文通過。

[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查看聚合組的詳細信息。

==================================================================

二，二層端口動态聚合配置

拓撲和上面配置靜态時一樣

配置SWA

創建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 //創建聚合組1

[SWA-Bridge-Aggregation1]link-aggregation mode dynamic //聚合為動态模式

------------------------------------------------------

分别把GE1/0/1,GE1/0/1,GE1/0/1加入到聚合組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

配置二層聚合接口1為Trunk端口，并允許VLAN 40和50的報文通過。

[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加入到聚合組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

配置二層聚合接口1為Trunk端口，并允許VLAN 40和50的報文通過。

[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查看聚合組的信息。
