Today development of computer and information technology, computer and network have been very popular. At the same time, security is important to secure the data, especially in campus environment. A campus network faces, many challenges such as IP address allocation, network failure, detecting rogue system user and determining slowing network etc., This research is mainly targeted towards campus networks which deliver the required security and best performance. To reduce the maximum wastage of IP address space using VLSM technique. A network is divided into different subnets. This technique will improve the security and traffic isolation. To improve the network speed on campus area network using etherchannel technique. This technique increases the network speed and redundant path between two devices. To multiple smaller broadcast domain using VLAN. To Communicate different VLAN using Inter-VLAN technique. This technique is implemented using multilayer switch. To secure and control a network traffic using VLAN Access Control List (VACL). Secured network protects an institution from security attacks associated with network. A campus network has a number of uses, such as education, research, learning, supervision, e-library, result publishing and association with the external users. Network security prevents the campus network from different types of threats and attack. The system can efficiently control and handle the reliable operation of the campus network.
