這篇文章將為大家詳細講解有關服務器中如何配置三層交換機，丸趣 TV 小編覺得挺實用的，因此分享給大家做個參考，希望大家閱讀完這篇文章后可以有所收獲。

實驗拓撲：

實驗目的：pc1、pc2、pc3、pc4、server-pt 實現互通

實驗需求：
pc1：ip 地址：192.168.10.1
子網掩碼：255.255.255.0
網關：192.168.10.254
pc2： ip 地址：192.168.20.1
子網掩碼：255.255.255.0
網關：192.168.20.254
pc3: ip 地址：192.168.30.1
子網掩碼：255.255.255.0
網關：192.168.30.254
pc4: ip 地址：192.168.40.1
子網掩碼：255.255.255.0
網關： 192.168.40.254
server-PT: ip 地址：192.168.60.1
子網掩碼：255.255.255.0
網關：192.168.60.254

實驗步驟：
1. 配置 PC 機
pc1

pc2
pc3

pc4

serve-pt

2. 配置二層交換機
操作內容：
a、sw1 和 sw2 分別創建 vlan10、vlan20 和 vlan30、vlan40，并將端口加入到各自對應的 vlan 中，與 PC 機相連的端口設置 access 模式且允許各自所在 vlan 通過，其余端口創建 trunk 模式且允許所有 vlan 通過
b、sw3 和 sw4 各自創建 vlan10、vlan20、vlan30、vlan40，將所有端口創建 trunk 鏈路且允許所有 vlan 通過

sw1：
Switch enable
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
