• VLAN的配置实例

    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

     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

    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。
