3. 配置步骤

(1)     配置Device A

#创建VLAN 10,并将端口GigabitEthernet1/0/4加入到该VLAN中。

<DeviceA> system-view

[DeviceA] vlan 10

[DeviceA-vlan10] port gigabitethernet1/0/4

[DeviceA-vlan10] quit

# 创建VLAN 20,并将端口GigabitEthernet1/0/5加入到该VLAN中。

[DeviceA] vlan 20

[DeviceA-vlan20] port gigabitethernet1/0/5

[DeviceA-vlan20] quit

#创建二层聚合接口1

[DeviceA] interface bridge-aggregation 1

[DeviceA-Bridge-Aggregation1] quit

#分别将端口GigabitEthernet1/0/1GigabitEthernet1/0/3加入到聚合组1中。

[DeviceA] interface gigabitethernet 1/0/1

[DeviceA-GigabitEthernet1/0/1] portlink-aggregation group 1

[DeviceA-GigabitEthernet1/0/1] quit

[DeviceA] interface gigabitethernet1/0/2

[DeviceA-GigabitEthernet1/0/2] portlink-aggregation group 1

[DeviceA-GigabitEthernet1/0/2] quit

[DeviceA] interface gigabitethernet1/0/3

[DeviceA-GigabitEthernet1/0/3] portlink-aggregation group 1

[DeviceA-GigabitEthernet1/0/3] quit

#配置二层聚合接口1Trunk端口,并允许VLAN 1020的报文通过。

[DeviceA] interface bridge-aggregation 1

[DeviceA-Bridge-Aggregation1] portlink-type trunk

[DeviceA-Bridge-Aggregation1] porttrunk permit vlan 10 20

[DeviceA-Bridge-Aggregation1] quit

(2)     配置Device B

DeviceB的配置与Device A相似,配置过程略。

4. 验证配置

#查看Device A上所有聚合组的详细信息。

以上信息表明,聚合组1为二层静态聚合组,包含有三个选中端口。


二层动态聚合配置举例

1. 组网需求

·     Device ADevice B通过各自的二层以太网接口GigabitEthernet1/0/1GigabitEthernet1/0/3相互连接。

·     DeviceADevice B上分别配置二层动态链路聚合组,并实现设备间VLAN 10VLAN 20分别互通。

总结:1、华三交换机的静态模式对应华为的默认模式,华三的动态模式对应华为的mode lacp模式。思科这边的话目前只实验过华为和思科的,华为为mode lacp,思科为mode active。

2、华三交换机做链路聚合时,需要先创建聚合接口1,然后在将端口GigabitEthernet1/0/1GigabitEthernet1/0/3加入到聚合组1中,最后配置二层聚合接口1Trunk端口,并允许VLAN 1020的报文通过。此处顺序绝对不能乱,否则链路聚合端口不会生效。华为的最后两部可以颠倒。

之前在做华为和华三的交换机聚合连接时,便出过这么一次问题,最后查阅了大量的资料,才发现是因为配置顺序问题导致通信失败,PS:这个问题真的是意向不到呀!
