PERANCANGAN JARINGAN ZERO LINK FAILURE PADA LAYER 2

Abstrak

High network availability is a primary requirement in modern enterprise environments, but disruptions due to link failures often hamper smooth operations. This study aims to design a Layer 2 network with Spanning Tree Protocol (STP) and EtherChannel technology to realize the concept of zero link failure, namely a network that is able to maintain connectivity automatically when a link failure occurs. The research method used is an experimental approach with Cisco Packet Tracer as a testing medium and network traffic analysis using Wireshark. The research process follows the PPDIOO (Prepare, Plan, Design, Implement, Operate, Optimize) stages which begin with an analysis of network requirements at PT. XYZ, topology design, and STP and EtherChannel configuration simulations to increase redundancy and bandwidth capacity. The simulation results show that this network design is able to maintain connectivity even if a failure occurs on one of the physical paths with a recovery time of less than 5 seconds, as well as significantly increasing network stability and throughput. The implementation of STP prevents looping, while EtherChannel combines multiple physical links into a single logical link that is resilient to failure. Although limited to simulation, this research provides practical solution recommendations for improving the reliability of Layer 2 networks at an enterprise scale. Further testing on real-world devices is highly recommended for validation and development of future implementations
