端口聚合

二层动态聚合配置举例

1. 组网需求

l              Device A与Device B通过各自的二层以太网端口GigabitEthernet1/0/1～GigabitEthernet1/0/3相互连接。

l              在Device A和Device B上分别配置二层动态链路聚合组，并使两端的VLAN 10和VLAN 20之间分别互通。

l              通过按照报文的源MAC地址和目的MAC地址进行聚合负载分担的方式，来实现数据流量在各成员端口间的负载分担。

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，并配置该接口为动态聚合模式。

[DeviceA] interface bridge-aggregation 1

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

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

[DeviceA] interface GigabitEthernet1/0/1

[DeviceA-GigabitEthernet1/0/1] port link-aggregation group 1

[DeviceA-GigabitEthernet1/0/1] quit

[DeviceA] interface GigabitEthernet1/0/2

[DeviceA-GigabitEthernet1/0/2] port link-aggregation group 1

[DeviceA-GigabitEthernet1/0/2] quit

[DeviceA] interface GigabitEthernet1/0/3

[DeviceA-GigabitEthernet1/0/3] port link-aggregation group 1

[DeviceA-GigabitEthernet1/0/3] quit

# 配置二层聚合接口1为Trunk端口，并允许VLAN 10和20的报文通过。

[DeviceA] interface bridge-aggregation 1

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

[DeviceA-Bridge-Aggregation1] port trunk permit vlan 10 20
