实验拓扑

实验需求

1. 按图示为PC配置IP地址
2. asw01和asw02上分别创建vlan10和vlan20，要求PC3和PC5属于vlan10，PC4和PC6属于vlan20
3. asw01和asw02相连的接口配置为trunk类型，允许vlan10和vlan20通过
4. 测试效果，同一vlan的PC可以互通，不同vlan的PC无法互通

实验解法

1. PC配置IP地址命令略
2. asw01和asw02上分别创建vlan10和vlan20

步骤1：在asw01上创建vlan10和vlan20

[asw01]vlan 10 20

步骤2：在SW2上创建vlan10和vlan20

[asw02]vlan 10 20

3.asw01和asw02都把GE_1/0/1接口加入vlan10，GE_1/0/2接口加入vlan20

步骤1：在asw01上把GE_1/0/1接口加入到vlan10，把GE_1/0/2接口加入到vlan20

[asw01]interface GigabitEthernet  1/0/1
[asw01-GigabitEthernet1/0/1]port access vlan  10 
[asw01-GigabitEthernet1/0/1]interface GigabitEthernet  1/0/2
[asw01-GigabitEthernet1/0/2]port access vlan  20

步骤2：在asw02上把GE_1/0/1接口加入到vlan10，把GE_1/0/2接口加入到vlan20

[asw02]interface GigabitEthernet  1/0/1
[asw02-GigabitEthernet1/0/1]port access vlan  10 
[asw02-GigabitEthernet1/0/1]interface GigabitEthernet  1/0/2
[asw02-GigabitEthernet1/0/2]port access vlan  20

4.asw01和asw02的GE_1/0/3接口都配置为trunk，允许vlan10和vlan20通过

步骤1：在asw01上把GE_1/0/3接口配置为Trunk类型，并允许vlan10和vlan20通过

[asw01]interface GigabitEthernet 1/0/3
[asw01-GigabitEthernet1/0/3]port link-type trunk 
[asw01-GigabitEthernet1/0/3]port trunk permit vlan 10 20

步骤2：在asw02上把GE_1/0/3接口配置为Trunk类型，并允许vlan10和vlan20通过

[asw02]interface GigabitEthernet 1/0/3
[asw02-GigabitEthernet1/0/3]port link-type trunk 
[asw02-GigabitEthernet1/0/3]port trunk permit vlan 10 20

5.测试结果，如下所示，PC3可以PING通PC5，但无法PING通PC4和PC6

步骤1：在PC3上PingPC4，发现不能Ping通

步骤3：在PC3上PingPC6，发现不能Ping通
