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之间使用动态链路聚合，并trunk放行vlan10，vlan20
步骤1：SWA上配置动态链路聚合，并trunk放行vlan10，vlan20
[SWA]interface Bridge-Aggregation 1 [SWA-Bridge-Aggregation1]link-aggregation mode dynamic [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上配置动态链路聚合，并trunk放行vlan10，vlan20
[SWB]int Bridge-Aggregation 1 [SWB-Bridge-Aggregation1]link-aggregation mode dynamic [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

用ping命令来检测PC1与PC2的互通性,结果是可以互通的
