局域网核心交换机6006备份方案

　　3.4

　　D： Catalyst 3548G XL交换机提供2个基于Gigabit Ethernet端口和48个10BaseT/100BaseTX端口。此交换机的端口：FastEthernet0/1到 FastEthernet0/36，以及GigabitEthernet0/1为缺省的VLAN1，10网段的，为3楼工作站提供接入服务；其余端口均为 VLAN8的8网段，为楼层交换机提供接入。详细配置为：

　　3.4

　　楼层交换机E： Catalyst 3548G XL交换机提供2个基于Gigabit Ethernet端口和48个10BaseT/100BaseTX端口。此交换机的端口均为8网段的。改动主要为与3楼中心交换机的连接的 GigabitEthernet端口改为10BaseT/100BaseTX端口。交换机的IP地址和缺省网关都不变。注：4楼交换机中的VLAN9要删除，改为缺省的8网段；2楼交换机要求重新配置为10网段的。

　　3.5

　　Cisco 3662提供2个快速以太网接口，分别为10网段和8网段，为两者提供3层交换，起到了原来Catalyst 6006中的路由模块的作用。具体接口配置为：

Interface FastEthernet0/0
IP address 192.168.10.254 255.255.255.0
!
Interface FastEthernet0/1
IP address 192.168.8.200 255.255.255.0 

　　在路由协议配置中加入：

router ospf 100
network 192.168.8.0 0.0.0.255 area 0 

　　改动中的几件重要事情：

　　1. 交换机之间的拆线和连线。

　　2. 几台交换机的配置要改动：D： Catalyst 3548XL的改动、4楼交换机的改动、2楼财务部7网段的改动；

　　3. Cisco 3662 路由器配置的改动。
