Experiment 1 of Spanning Tree Protocol: Regarding a robust network in this experiment, there should be redundancy. But when the network has redundancy, it brings about issues such as MAC address jitter, duplicate frames, and loops. These issues all require the Spanning Tree Protocol (STP) to avoid. STP will block redundant links in the network that may cause loops to ensure that there is only one logical path in the network, and STP will constantly detect the availability of logical paths. When a fault occurs, it will enable blocked redundant links, So that the network has the ability to "self-heal" 2. Configure experimental objectives and understand STP; Configure and understand RSTP
4 Experimental resources: 5 switches (supporting Huawei Version 5.110 mirrored Huawei S3700 or similar switches, or using Huawei eNSP emulator version 3.9 and above) 2 PCs (using Windows 7 or Windows 10 operating systems or using Huawei ESP emulator version 3.9 and above) 5 Experimental task 5.1 Configure STP to master root bridge control methods, master port role control methods, understand the role of time values, and modify methods Configuration idea: Step 1: First, modify the default spanning tree mode of the switch to STP. Step 2: Control the root bridge in the network by modifying the bridge priority. Step 3: Next, on a non root bridge, based on the three principles of root port selection - first, compare the Cost value to the root bridge, then compare the sent bridge ID, and then compare the sender's Port ID to control the election of the root port separately. Step 4: Observe the convergence of the STP protocol by changing the port state in LSW5
