計算機網絡技術實踐

實驗報告

實驗名稱:基本互換機使用及VLAN配置

姓名：實驗日期：2023年5月4日

學號:實驗報告日期：2023年5月4日

環(huán)境（具體說明運營的操作系統(tǒng)，網絡平臺，網絡拓撲圖）

操作系統(tǒng)：Windows7

網絡平臺:軟件Dynamips環(huán)境下的虛擬網絡

網絡拓撲：

—.實驗目的

令掌握以太網互換機的使用方法,可以在模擬環(huán)境中使用以太網互換機組建局域網。

令掌握以太網互換機的VLAN劃分和配置方法，可以在模擬環(huán)境中使用以太網互換機

組建虛擬局域網。

三.實驗內容及環(huán)節(jié)（涉及重要配置流程，重要部分需要截圖）

1、設計網絡物理拓撲和邏輯網段,如上圖

2、修改拓撲文獻
