摘要
目的:快速定位隐藏的目标交换机。方法:利用交换机端口缓存的NDP信息表中记录的MAC地址,查找端口的ARP信息表中对应的交换机管理IP地址,最终使用远程登录技术连接至交换机。结果:该方法应用到医院医疗网和互联网中,当使用满12位的MAC地址时,查找到目标交换机的准确率为85.3%,平均耗时0.31秒;当使用前9位的MAC地址时,查找准确率为100%,平均耗时1.72秒。结论:该方法能够准确快速地查找到隐藏在网络中的交换机的管理IP地址。
Objective： To locate the target network switch hidden in the network efficiently. Methods： By using the MAC address in the NDP cache tables of the Switch port, the IP address of the corresponding switch can be found through ARP information tables. And then the remote log＇in technology can be applied to connect to the switch. Results： Practical applications of this method on the internet network system and the medical network system of our hospital show high precision and time efficient. When the MAC address in use reached a full 12 bits, the precision was 85.3% and costed 0.31 second on average; and the precision was 100% and costed 1.72 second on average when the MAC address in use was the first 9 bits. Conclusion： Our method can be used to seek out the hidden network switch accurately and rapidly.
