Abstract: SPANNING TREE PROTOCOL (STP) OVERVIEWSpanning Tree Protocol (STP) is a Layer 2 protocol essential in Ethernet networks to prevent network loops.Redundant paths in a network can cause: 1) Broadcast storms: Excessive traffic that floods the network.2) Multiple frame copies: Duplication of frames, creating confusion.3) MAC table instability: Incorrect MAC address mapping due to looped traffic.STP ensures there is always a single active path between devices in a network by blocking redundant paths until needed. II. KEY FEATURES OF TRADITIONAL STP 1) IEEE Standard: Defined by the IEEE 802.1D specification.2) Root Bridge Election: Utilizes Bridge Protocol Data Units (BPDUs) to elect a Root Bridge, which acts as the central reference point in the network topology.3) Port States: Blocking: Prevents loops by not forwarding frames. Listening: Monitors BPDUs but doesn't forward traffic. Learning: Builds MAC address tables without forwarding frames. Forwarding: Operates normally by forwarding frames. Disabled: No activity on the port.
