What are the limitations of Classic Spanning Tree (802.1d) and how do newer versions like Per VLAN Spanning Tree (PVST) and Rapid Spanning Tree (802.1w) address these limitations?
Classic Spanning Tree Protocol (STP), defined in IEEE 802.1d, is a fundamental mechanism used in Ethernet networks to prevent loops in bridged or switched networks. However, it comes with certain limitations that have been addressed by newer versions such as Per VLAN Spanning Tree (PVST) and Rapid Spanning Tree Protocol (RSTP, 802.1w). One of the
What role do Bridge Protocol Data Units (BPDUs) and Topology Change Notifications (TCNs) play in network management with STP?
Bridge Protocol Data Units (BPDUs) and Topology Change Notifications (TCNs) are important elements in the operation and management of networks utilizing the Spanning Tree Protocol (STP). STP is a network protocol that ensures loop-free topology in Ethernet networks by dynamically disabling and enabling ports to prevent broadcast storms and ensure network stability. BPDUs and TCNs
Explain the process of selecting root ports, designated ports, and blocking ports in Spanning Tree Protocol (STP).
Spanning Tree Protocol (STP) is a vital component in computer networking to prevent loops in Ethernet networks. The process of selecting root ports, designated ports, and blocking ports in STP is important for ensuring a loop-free topology. Firstly, STP elects a root bridge within the network. The bridge with the lowest Bridge ID becomes the

How do switches determine the root bridge in a spanning tree topology?
Spanning Tree Protocol (STP) is a important mechanism in computer networking that prevents loops in Ethernet networks by creating a loop-free logical topology. The Root Bridge is a central concept in STP as it serves as a reference point for all other switches in the network. Switches determine the Root Bridge by comparing Bridge IDs,

What is the primary purpose of Spanning Tree Protocol (STP) in network environments?
The primary purpose of the Spanning Tree Protocol (STP) in network environments is to prevent loops in Ethernet networks. Loops occur when there are multiple active paths between switches in a network, causing broadcast storms and network congestion. STP works by dynamically calculating a loop-free logical topology, allowing for redundant links while ensuring a single
