H3C交換機配置鏈路聚合二層三層

二層聚合：

一、靜態聚合

[SW]int Bridge-Aggregation 1

[SW-Ethernet1/0/1]port link-aggregation group 1

[SW-Ethernet1/0/2]port link-aggregation group 1

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

[SW-Bridge-Aggregation1]port trunk permit vlan all 必須先加入端口再起Trunk，要不然會出錯

二、動態聚合

[SW]int Bridge-Aggaregation 1

[SW-Bridge-Aggregation1]link-aggregation mode dynamic

[SW-Ethernet1/0/1]port link-aggregation group 1

[SW-Ethernet1/0/2]port link-aggregation group 1

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

[SW-Bridge-Aggregation1]port trunk permit vlan all

查看命令：

display link-aggregation summary

[S1]display link-aggregation verbose

負載分擔：

[S1]link-aggregation load-sharing mode destination-mac 兩端都配置（貌似接口也可以配置）

三層聚合：

[R2]int Route-Aggregation 1

[R2-Route-Aggregation1]ip add 12.1.1.2 24

[R2]int g0/0

[R2-GigabitEthernet0/0]port link-aggregation group 1

[R2-GigabitEthernet0/0]int g0/1

[R2-GigabitEthernet0/1]port link-aggregation group 1

負載分擔：

[R1]link-aggregation global load-sharing mode source-ip destination-ip基於源IP，目的IP
