Abstract: Since all the network experiments are forbidden in the real network environment， how to train a qualified network administrator in the real network environment is a tough issue. A network management training platform was designed and implemented， which was capable of providing diversified experiments scenes. The platform proposed could be used to train the necessary skills for network administration， such as large networks implementation， network fault detection and recovery， network topology discovery， network attack and defense. Both the experiment of routing oscillation caused by human error in configuration and the experiment of maninthemiddle attack of neighbor discovery for IPv6 proved that the platform was capable of serving as a test bed to provide a research environment for network administrators.
