网络规划参考

发布日期：2012-03-15 浏览次数：393

核心提示：公司新搬了地方，新地方的网络进行了重新规划，在搬家期间，参与了相关的规划和实施过程，让我受益非浅，现摘录如下：公司现有PC数量近500台，服务器的数量有近20台，新厂为增加网络的稳定性和易管理性，在原有的基础上采购了两台CISCO 3750(核心层)，10台CISCO CE500(楼间层)，28台3COM(桌面层)的桌面型交换机，2台CISCO 2600，需要实现的要求如下：

　　１：两台3750作为核心交换，堆叠．

　　２：网络划分为7个VLAN，其中分为默认区(192.168.88.x)，服务器网段(192.168.42.x)，办公区(192.168.40.x 192.168.43.x)，制造区(192.168.41.x)，无线区(192.168.44.x)和其它区(192.168.46.x)．

　　３：各个网段中客户端的IP通过服务器DHCP分配．

　　４：服务器段里的服务器接入3750以实1G的接入速度．

　　５：办公区中电脑以前安装有多台打印服务器，网段为42.x，为了简化客户端操作，需在楼间层CE500上设置其它的桌面交换机分属不同的网段．

　　６：各个办公区的电脑通过域服务器的用户名验证经Watch Guard防火墙控制其上网权限，因为有外厂客户访问，所以设置无线区实现无限制的外网连接．但是由交换机控制其不能进行内网访问．
