發布時間：2023/12/16 windows 37 豆豆

生活随笔收集整理的這篇文章主要介紹了航天恒星系统集成项目组小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

項目拓撲：

項目背景：

航天恒星科技股份有限公司是由中國空間技術研究院（五院）控股的衛星應用高科技股份公司，注冊資本1.37億元。公司是中國空間技術研究院衛星應用的總體單位與產業化發展平臺，承擔著背景型號天地一體化系統論證、地面應用系統開發，也是中國空間技術研究院衛星應用產品研發、制造中心和市場拓展平臺。主要業務領域包括衛星地面綜合應用、衛星導航、衛星遙感和圖像傳輸、衛星通信與廣播電視傳輸。

航天恒星科技股份有限公司（西安分部）

地址：西安市高新區錦業路70號

郵編：710065

項目要求：

1. 辦公大樓部分

a：VLAN 的劃分技術部—vlan 2 財務部—vlan 3 市場部—vlan 4 VLAN1(移動設備）

b：VLAN 在三層交換機上路由

c：三層交換機學習路由器R1的路由采用RIP協議

d：做好遠程管理工作

2.網絡管理中心實現本單位的網絡管理工作

3.服務器機房，主要存放單位的網站服務器和其他服務器

4.R3默認路由指向網絡出口R4； R4靜態路由連接內網

5.生產車間接入網絡

6.網站海外部（外貿部）接入網絡（使用無線網絡）提高移動辦公能力

7.早期辦公樓接入網絡，使用RIP協議。

8.R4光纖外部接入：10M

項目過程：

1、給PC:技術部--vlan 2 財務部--vlan 3 市場部--vlan 4 VLAN1(移動設備）

192.168.1.0-192.168.4.0

2、VLAN

核心交換機的配置：

試驗成功。

注釋：SSID

SSID/ESSID（Service Set Identifier）也就是“服務區標識符匹配”、“業務組標識符”的簡稱，最多可以有32 個字符，通俗的說，它就好比有線局域網中的“工作組”標識一樣或好比是無線客戶端與無線路由器之間的一道口令一樣，只有在完全相同的前提下才能讓無線網卡訪問無線路由器，這也是保證無線網絡安全的重要措施之一。

配備無線網卡的無線工作站必須填寫正確的SSID，并與無線訪問點（AP 或無線路由器）的SSID相同，才能訪問AP；如果出示的SSID 與AP 或無線路由器的SSID 不同，那么AP 將拒絕他通過本服務區/工作組上網。因此可以認為SSID 是一個簡單的口令，從而提供口令認證機制，實現一定的安全。

要更改無線網卡的SSID 除了在無線網卡配置程序中更改外，還可在操作系統中直接更改。
