静态链路聚合实验

实验拓扑

实验需求

按照图示搭建拓扑并配置IP地址
将SWA和SWB的g1/0/4加入到vlan10中，g1/0/5加入到vlan20中
SWA和SWB之间使用静态链路聚合，并trunk放行vlan10，vlan20
测试，用ping命令来检测PC1与PC2的互通性

实验解析

1、配置IP地址

步骤1：配置PC1的IP地址

步骤2：配置PC2的IP地址

步骤3：配置PC3的IP地址

步骤4：配置PC4的IP地址

2、将SWA和SWB的g1/0/4加入到vlan10中，g1/0/5加入到vlan20中

步骤1：将SWA的g1/0/4加入到vlan10中，g1/0/5加入到vlan20中

[SWA]vlan 10
[SWA-vlan10]port g1/0/4
[SWA-vlan10]vlan 20
[SWA-vlan20]port g1/0/5

步骤2：将SWB的g1/0/4加入到vlan10中，g1/0/5加入到vlan20中

[SWB]vlan 10
[SWB-vlan10]port g1/0/4
[SWB-vlan10]vlan 20
[SWB-vlan20]port g1/0/5

3、SWA和SWB之间使用静态链路聚合，并trunk放行vlan10，vlan20

步骤1：SWA上配置静态链路聚合，并trunk放行vlan10，vlan20

[SWA]interface Bridge-Aggregation 1
[SWA-Bridge-Aggregation1]qu
[SWA]int range g1/0/1 g1/0/2 g1/0/3 
[SWA-if-range]port link-aggregation group 1
[SWA-Bridge-Aggregation1]port link-type trunk 
[SWA-Bridge-Aggregation1]port trunk permit vlan 10 20

步骤2：SWB上配置静态链路聚合，并trunk放行vlan10，vlan20

[SWB]int Bridge-Aggregation 1
[SWB-Bridge-Aggregation1]qu
[SWB]int range g1/0/1 g1/0/2 g1/0/3
[SWB-if-range]port link-aggregation group 1
[SWB-Bridge-Aggregation1]port link-type trunk 
[SWB-Bridge-Aggregation1]port trunk permit vlan 10 20

4、用ping命令来检测PC1与PC2的互通性

分别在SWA和SWB上通过display link-aggregation verbose 来显示链路聚合的详细信息

<SWA>display link-aggregation verbose 
Loadsharing Type: Shar -- Loadsharing, NonS -- Non-Loadsharing 
Port Status: S -- Selected, U -- Unselected, I -- Individual 
Port: A -- Auto port, M -- Management port, R -- Reference port 
Flags:  A -- LACP_Activity, B -- LACP_Timeout, C -- Aggregation, 
        D -- Synchronization, E -- Collecting, F -- Distributing, 
        G -- Defaulted, H -- Expired

  GE1/0/3          S       32768    1

  GE1/0/3          S       32768    1

用ping命令来检测PC1与PC2的互通性,结果是可以互通的
