   這個實驗記錄隨着學習進度的進行不斷進行更新，主要爲基於華爲eNSP環境下進行的熟悉計算機網絡的相關實驗，這個實驗主要爲熟悉掌握計算機網絡的結構和工作原理，深入理解交換機、路由器、無限網絡的工作原理，目前這個實驗包括下面幾個內容：

  • 單臺PC機聯通交換機的實驗配置
  • 單臺交換機上使用VLAN來隔離PC
  • 跨交換機實現不同VLAN的通信與隔離
  • 不同VLAN間實現通信

實操圖如下 (#_#)

跨交換機實現不同VLAN的通信與隔離

相關操作如下所示：

  1. 配置兩臺交換機的接口VLAN
  2. 配置交換機與PC的端口連接
  3. 配置交換機端口間的連接方式
  4. 配置PC的ip地址
  5. 驗證PC機兩兩之間的連通性

在這裏解釋一下兩臺交換機之間進行的trunk，trunk是端口進行匯聚的意思，它允許交換機與交換機、交換機與路由器、主機與交換機或路由器之間通過兩個或多個端口並行進行連接，同時傳輸來提供更高的帶寬、更大的吞吐量，大幅度提高整個網絡能力。VLAN trunk是指設置了多個VLAN之後，想通過一個端口來傳輸我們設置的多個VLAN，我們就需要在交換機這裏設置這個端口爲trunk。trunk技術使得一條物理線路可以傳送多個VLAN的數據，更加具體的細節你想了解的話可以去查查資料。
