网络管理设计方案

一.网络拓扑图二.项目实施步骤1.做好需求分析2.依照需求分析做好网络拓扑图3.依照网络拓扑图找到需要相关技术4.实现和完善各种技术5.测试与总结三.IP地址规划1.VLAN规划网络设备ip规划四.网络设备选型二层交换机第二层交换机依赖于数据链路层信息（如MAC地址）完成丌同端口间数据线速交换，它对网络协议和用户应用程序完全是透明。第二层交换机经过内建一张MAC地址表来完成数据转发决议。接入层交换机通常全部采取第二层交换机。三层交换机第三层交换机具备第二层交换机交换功效和第三层路由器路由功效，可将IP地址信息用于网络路径选择，并实现丌同网段间数据快速交换。当网络规模较大或经过划分VLAN来减小广播所造成影响时，只有借助第三层交换机才能实现。在大中型网络中，关键层交换机通常都由第三层交换机来充当。当然，一些网络应用较为复杂汇聚层交换机也能够选取第三层交换机。路由器使用路由器连接网络系统因能够将机器分成多个广播域，所以能够方便控制一个网络大小。另外，路由器还能够支持一定服务等级（服务优先级别）。因为路由器每端口造价相对较贵，在使用之前还要求用户迚行大量配置工作，所以，企业级路由器成败就在于是否可提供一定数量低价端口、是否容易配置、是否支持QoS、是否支持广播和组播等多项功效五,测试两台路由器、一台三层交换机、三台二层交换机两台服务器试验配置文档：VLAN10交换机：SWC#showrunBuildingconfiguration...Currentconfiguration:1423bytes!version12.1noservicepassword-encryption!hostnameSWC!!!interfaceFastEthernet0/1!interfaceFastEthernet0/2!interfaceFastEthernet0/3switchportmodetrunk!interfaceFastEthernet0/4!interfaceFastEthernet0/5switchportaccessvlan10!interfaceFastEthernet0/6switchportaccessvlan10!interfaceFastEthernet0/7switchportaccessvlan10!interfaceFastEthernet0/8switchportaccessvlan10!interfaceFastEthernet0/9switchportaccessvlan10!interfaceFastEthernet0/10switchportaccessvlan10!interfaceFastEthernet0/11switchportaccessvlan10!interfaceFastEthernet0/12switchportaccessvlan10!interfaceFastEthernet0/13switchportaccessvlan10!interfaceFastEthernet0/14switchportaccessvlan10!interfaceFastEthernet0/15switchportaccessvlan10!interfaceFastEthernet0/16switchportaccessvlan10!interfaceFastEthernet0/17switchportaccessvlan10!interfaceFastEthernet0/18switchportaccessvlan10!interfaceFastEthernet0/19switchportaccessvlan10!interfaceFastEthernet0/20switchportaccessvlan10!interfaceFastEthernet0/21switchportaccessvlan10!interfaceFastEthernet0/22switchportaccessvlan10!interfaceFastEthernet0/23switchportaccessvlan10!interfaceFastEthernet0/24switchportaccessvlan10!interfaceVlan1noipaddressshutdown!linecon0!linevty04loginlinevty515login!!endVLAN20交换机：SWB>enableSWB#showrunBuildingconfiguration...Currentconfiguration:1400bytes!version12.1noservicepassword-encryption!hostnameSWB!!!interfaceFastEthernet0/1!interfaceFastEthernet0/2!interfaceFastEthernet0/3!interfaceFastEthernet0/4!interfaceFastEthernet0/5switchportaccessvlan20!interfaceFastEthernet0/6switchportaccessvlan20!interfaceFastEthernet0/7switchportaccessvlan20!interfaceFastEthernet0/8switchportaccessvlan20!interfaceFastEthernet0/9switchportaccessvlan20!interfaceFastEthernet0/10switchportaccessvlan20!interfaceFastEthernet0/11switchportaccessvlan20!interfaceFastEthernet0/12switchportaccessvlan20!interfaceFastEthernet0/13switchportaccessvlan20!interfaceFastEthernet0/14switchportaccessvlan20!interfaceFastEthernet0/15switchportaccessvlan20!interfaceFastEthernet0/16switchportaccessvlan20!interfaceFastEthernet0/17switchportaccessvlan20!interfaceFastEthernet0/18switchportaccessvlan20!interfaceFastEthernet0/19switchportaccessvlan20!interfaceFastEthernet0/20switchportaccessvlan20!interfaceFastEthernet0/21switchportaccessvlan20!interfaceFastEthernet0/22switchportaccessvlan20!interfaceFastEthernet0/23switchportaccessvlan20!interfaceFastEthernet0/24switchportaccessvlan20!interfaceVlan1noipaddressshutdown!linecon0!linevty04loginlinevty515login!!endVLAN30交换机：SWD>enableSWD#showrunBuildingconfiguration...Currentconfiguration:1423bytes!version12.1noservicepassword-encryption!hostnameSWD!!!interfaceFastEthernet0/1!interfaceFastEthernet0/2!interfaceFastEthernet0/3!interfaceFastEthernet0/4switchportmodetrunk!interfaceFastEthernet0/5switchportaccessvlan30!interfaceFastEthernet0/6switchportaccessvlan30!interfaceFastEthernet0/7switchportaccessvlan30!interfaceFastEthernet0/8switchportaccessvlan30!interfaceFastEthernet0/9switchportaccessvlan30!interfaceFastEthernet0/10switchportaccessvlan30!interfaceFastEthernet0/11switchportaccessvlan30!interfaceFastEthernet0/12switchportaccessvlan30!interfaceFastEthernet0/13switchportaccessvlan30!interfaceFastEthernet0/14switchportaccessvlan30!interfaceFastEthernet0/15switchportaccessvlan30!interfaceFastEthernet0/16switchportaccessvlan30!interfaceFastEthernet0/17switchportaccessvlan30!interfaceFastEthernet0/18switchportaccessvlan30!interfaceFastEthernet0/19switchportaccessvlan30!interfaceFastEthernet0/20switchportaccessvlan30!interfaceFastEthernet0/21switchportaccessvlan30!interfaceFastEthernet0/22switchportaccessvlan30!interfaceFastEthernet0/23switchportaccessvlan30!interfaceFastEthernet0/24switchportaccessvlan30!interfaceVlan1noipaddressshutdown!linecon0!linevty04loginlinevty515login!!end三层交换机：SA>enableSA#showrunBuildingconfiguration...Currentconfiguration:1462bytes!version12.2noservicepassword-encryption!hostnameSA!!!!!ipsshversion1!port-channelload-balancesrc-mac!interfaceFastEthernet0/1switchportmodetrunk!interfaceFastEthernet0/2switchportmodetrunk!interfaceFastEthernet0/3switchportmodetrunk!interfaceFastEthernet0/4switchportmodetrunk!interfaceFastEthernet0/5noswitchportipaddress192.168.40.2255.255.255.0duplexautospeedauto!interfaceFastEthernet0/6switchportaccessvlan50!interfaceFastEthernet0/7!interfaceFastEthernet0/8!interfaceFastEthernet0/9!interfa
