一個具體的網絡規劃

　　公司新搬了地方，新地方的網絡進行了從新規劃，在搬家期間，參與了相關的規劃和實施過程，讓我受益非淺，現摘錄以下：公司現有PC數量近500臺，服務器的數量有近20臺，新廠爲增長網絡的穩定性和易管理性，在原有的基礎上採購了兩臺CISCO 3750(核心層)，10臺CISCO CE500(樓間層)，28臺3COM(桌面層)的桌面型交換機，2臺CISCO 2600，須要實現的要求以下：

　　１：兩臺3750做爲核心交換，堆疊．

　　２：網絡劃分爲7個VLAN，其中分爲默認區(192.168.88.x)，服務器網段(192.168.42.x)，辦公區(192.168.40.x 192.168.43.x)，製造區(192.168.41.x)，無線區(192.168.44.x)和其它區(192.168.46.x)．

　　３：各個網段中客戶端的IP經過服務器DHCP分配．

　　４：服務器段裏的服務器接入3750以實1G的接入速度．

　　５：辦公區中電腦之前安裝有多臺打印服務器，網段爲42.x，爲了簡化客戶端操做，需在樓間層CE500上設置其它的桌面交換機分屬不一樣的網段．

　　６：各個辦公區的電腦經過域服務器的用戶名驗證經Watch Guard防火牆控制其上網權限，由於有外廠客戶訪問，因此設置無線區實現無限制的外網鏈接．可是由交換機控制其不能進行內網訪問．
