VLAN的配置实例

news2025/2/24 9:10:55

基于端口的vlan划分

以下配置为例： 注意选择copper线，可以任意选择端口

 PC配置如下：

LSW1配置如下 

[LSW1]vlan 10
[LSW1-vlan10]qu
[LSW1]interface g0/0/9
[LSW1-Gigabitethernet0/0/9] port link-type acces
[LSW1-Gigabitethernet0/0/9] port default vlan 10

 统一创建vlan的命令

#批量创建2....100

vlan batch 2 to 100  

 华为端口恢复默认配置的命令

撤销操作或命令直接在命令前面加 undo 

不同的vlan之间逻辑上是隔离的，不能相互通信

从以下信息可以看出，PC1可以与PC2进行通信，但是PC1不能与PC3,PC4相互通信

至此，PC-BOOK-10-1加入vlan 10，PC-BOOK-30-1加入vlan30

将 PC-BOOK-10-1和PC-BOOK-30-1所连接的交换机端口互换，依旧可以与同一个vlan中的计算机通信

查看捕获的以太网帧是否带标记，首先需要显示vlan id，步骤如下：

编辑--->首选项

number下拉，选择802.1Q VLAN id 

 

这里对LSW1的g0/0/9进行抓包，其link-type为access

对于普通终端的连接，是不需要vlan标记的

这里对LSW1的g0/0/24进行抓包，其link-type为trunk，并且带vlan标记，用于标识该数据帧属于哪个 VLAN。
