Implementation of Secured Wired and WLAN Network Using eNSP

WLAN is a key component of computer networking courses. For a better understanding of the WLAN concept, this paper plans the implementation of a secured wired and wireless LAN network on the eNSP modeling platform where an experimental environment is created, network connections are implemented through AC and AP configurations, and cellular users can also travel in wireless network coverage. At the same moment, we configure firewall for security purposes, configure, and analyze principles of networking protocols (LACP, MSTP, DHCP, VRRP, BFD, OSPF, IS-IS, CAPWAP, and WLAN802.11b), use Wireshark to intercept protocols, and check the wireless terminal roaming. This implementation also enhances the basic principle and data analysis capabilities of WLAN technology.
