IEEE 802.1D

IEEE 802.1D is a set of networking standards that manages how switches in a local network communicate and prevent data collisions. It uses a process called Spanning Tree Protocol (STP) to design a loop-free path, ensuring data is efficiently and reliably delivered without getting stuck in endless loops. Essentially, it helps maintain an organized, stable network by automatically disabling redundant links, so data flows smoothly, and network failures are minimized. This standard is fundamental in creating resilient Ethernet networks, especially in complex setups with multiple interconnected switches.
