摘要
网络管理中实现用户IP快速定位,从而获得用户上网的交换机端口,以便对用户的网络行为进行监测控制,有着重要的意义。一般需要通过网管人员手工在交换机上查询。文中指出了在思科网络环境下利用思科设备CDP协议并结合交换机ARP表和桥接表使用多表映射方法实现用户IP定位。在其基础上进一步提出了多种设备混合网络中的定位方案,并用代码实现。最后根据实际网络中运行时的稳定性,可靠性,兼容性,独立性问题提出了一些看法。
It is great important to implement user IP quick locating , then get the swich port which user＇s PC is connecting with , so that it can watch and control user＇s network behavior . Normally , network manager have to find the port artifically. In this article , It introduces in the Cisco network environment , the locating function can be achieved by using the CDP which is the Cisco＇s private link layer protocol and switch＇s ARP table and Bridge table ＇s content through mapping muhi tables. Based upon this , persents a new locating method which is applicable in mixed network environment with different equipment. At last , this article puts forwards some opinions towards the running problems about stability, reliability, compatibility, independencity in practical network enviroment.
