The new way of configuration management of network devices under mutable environment

Network Environment keeps stable usually, but under some extreme cases, the network environment changes regularly. The campus network located at classrooms is a typical case. The right of classroom internet access has been changed according to curriculum schedule. Thus, the network managers have to re-configure the network devices frequently for permitting or forbidding student computers access internet. In this paper, the protocol of telnet was discussed and an idea of network devices automatic configuration based on Telnet, script language and database was prompted. The experiment program of the configuration management of network devices system based on Rujie switches was introduced in detail.
