現有一台華為s5700交換機和普通交換機數台，以及tp-link路由器一台。
1.tp-link路由器連接配接外網。
2.s5700交換機劃分vlan。
3.普通交換機接vlan和pc端。
網絡拓撲圖如下：
配置說明：
s5700預設有vlan1所有端口都在vlan1裡面。
vlanif1配置路由器網段ip用于連接配接路由器。
三層交換機要配置一條指向路由器的靜态路由。
路由器要配置nat對應個vlan ip。
路由器要配置路由到各個vlan網段。
1.s5700交換機web管理ip和使用者配置。
使用Console線纜将計算機連接配接至交換機的Console口。
在計算機上打開終端仿真軟體，建立連接配接，設定連接配接的端口以及通信參數。計算機終端的通信參數配置要和交換機Console口的預設配置保持一緻，交換機Console口的預設配置如下：
傳輸速率：9600
資料位：8
校驗方式：無
停止位：1
流控方式：無
按Enter鍵，直到仿真終端出現如下顯示，提示使用者配置驗證密碼。
Please configure the login password (6-16)
Enter Password:123456789
Confirm Password:123456789
配置交換機的管理IP。

使用網線将計算機與交換機的ETH口相連,配置計算機上的IP。在尚未使用的IP位址範圍内選擇IP位址，如10.255.4.50。
打開一個Web浏覽器視窗。在位址欄中輸入10.255.4.50，即交換機IP位址，然後按Enter鍵。系統将顯示登入界面。
2.s5700vlan劃分和設定。
console登陸交換機，按enter鍵輸入密碼：123456789。
設定端口的接入方式和所屬的vlan
