Network+ Module 24 - Spanning Tree Protocol

These flashcards cover key concepts and terms related to the Spanning Tree Protocol as discussed in the lecture.

Spanning Tree Protocol (STP)

A network protocol designed to prevent broadcast loops in Ethernet networks by blocking certain ports on switches.

Broadcast Storm

A condition caused by broadcast loops that occurs when multiple switches continually send broadcast frames, rendering the network inoperable.

Bridge Protocol Data Units (BPDU)

Messages exchanged by switches containing information about the bridge ID and the topology of the network.

Root Bridge

The switch with the lowest Bridge Protocol Data Unit (BPDU) that serves as the central point of the spanning tree.

Root Port

The port on a non-root switch that forwards traffic towards the root bridge and is determined by the lowest path cost.

Bridge ID (BID)

An identifier comprising a priority number, VLAN ID, and MAC address, used to establish the root bridge.

Designated Port

The port on a network switch that has the best path to the root bridge and is responsible for forwarding traffic towards that bridge. It is designated for the specific network segment.
