5110,5100二层交换机能做端口汇聚吗？

 二层静态聚合配置举例

1. 组网需求

·     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。

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

·     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 gigabitethernet 1/0/4

[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 gigabitethernet 1/0/5

[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GigabitEthernet1/0/1至GigabitEthernet1/0/3加入到聚合组1中。

[DeviceA] interface gigabitethernet 1/0/1

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

[DeviceA-GigabitEthernet1/0/1] quit

[DeviceA] interface gigabitethernet 1/0/2

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

[DeviceA-GigabitEthernet1/0/2] quit

[DeviceA] interface gigabitethernet 1/0/3

[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

 Please wait... Done.

 Configuring GigabitEthernet1/0/1... Done.

 Configuring GigabitEthernet1/0/2... Done.

 Configuring GigabitEthernet1/0/3... Done.

[DeviceA-Bridge-Aggregation1] quit

# 配置全局按照报文的源MAC地址和目的MAC地址进行聚合负载分担。

[DeviceA] link-aggregation load-sharing mode source-mac destination-mac

(2)     配置Device B

Device B的配置与Device A相似，配置过程略。

(3)     检验配置效果

# 查看Device A上所有聚合组的摘要信息。

[DeviceA] display link-aggregation summary

Aggregation Interface Type:

BAGG -- Bridge-Aggregation, RAGG -- Route-Aggregation

Aggregation Mode: S -- Static, D -- Dynamic

Loadsharing Type: Shar -- Loadsharing, NonS -- Non-Loadsharing

Actor System ID: 0x8000, 000f-e2ff-0001

以上信息表明，聚合组1为负载分担类型的二层静态聚合组，包含有三个选中端口。

# 查看Device A上全局采用的聚合负载分担类型。

[DeviceA] display link-aggregation load-sharing mode

Link-Aggregation Load-Sharing Mode:

  destination-mac address, source-mac address

以上信息表明，所有聚合组都按照报文的源MAC地址和目的MAC地址进行聚合负载分担。

1.8.2  二层动态聚合配置举例

1. 组网需求

·     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。

·     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。

·     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。
