交換機：學習、廣播、轉發、更新。二層交換機屬於數據鏈路層設備。相同網段通交換。web

路由器：識別數據包目標IP、源IP、發現和選擇路徑、維護路由信息。路由器屬於網絡層設備。不一樣網段通路由。後端

衝突域：物理層電信號衝突範圍。網絡

廣播域：一個網段屬於一個廣播域。app

Vlan:物理設備上鍊接不受物理位置限制的邏輯用戶組。dom

相同網段交換，不一樣網段路由。交換機分割了衝突域不能分割廣播域，爲了分割廣播域引入Vlan。ide

Vlan 2的12次方4096 0-4095 1-4094學習

Access模式:同一時刻傳輸一個Vlan無標籤通常連接非交換機
ui

Trunk模式：同一時刻傳輸多個Vlan帶標籤通常連接交換機spa

實驗名稱：交換機配置Vlan

實驗拓撲：

實驗步驟：四臺PC分別設置ip和子網掩碼

192.168.1.1 255.255.255.0

192.168.1.2 255.255.255.0

192.168.1.3 255.255.255.0

192.168.1.4 255.255.255.0

建立Vlan

配置封端口模式

將端口加入Vlan

驗證並保存

實驗總結：相同Vlan通不一樣Vlan默認不通

華爲交換機刪除Vlan後端口自動回到Vlan1，有批量建立Vlan

思科交換機先移除端口再移除Vlan，無批量建立Vlan

實驗華爲交換機配置Vlan命令：
