There are many different options available when configuring an interface on a switch. In this video, you’ll learn about basic interface settings, VLAN configurations, power over Ethernet, and much more. << Previous Video: Spanning Tree Protocol Next: Static and Dynamic Routing >> One of the most basic interface configurations you need to make on any […]

We rely on STP to prevent loops on our switched networks. In this video, you’ll learn the fundamentals of Spanning Tree Protocol and how STP reacts when changes occur to the network. << Previous Video: Network Segmentation Next: Switch Interface Properties >> Ethernet switches are fantastic devices to use for networking, and to connect two

We commonly use network segmentation technologies to provide security and separation between logical areas of the network. In this video, you’ll learn about physical segmentation, logical VLAN segmentation, and 802.1Q VLAN trunking. << Previous Video: Protocol Data Units Next: Spanning Tree Protocol >> Here’s a common network configuration that involves two separate switches with two

PDUs are the building blocks of network communication. In this video, you’ll learn about protocol data units and how they are used at different layers of the OSI model. << Previous Video: Unicasts, Broadcasts, and Multicasts Next: Network Segmentation >> A protocol data unit, or a PDU, is a unit of information that is sent

There are many different ways to communicate across the network. In this video, you’ll compare the differences between unicasts, broadcasts, and multicasts. << Previous Video: Broadcast Domains and Collision Domains Next: Protocol Data Units >> In network communication, an unicast is what one device is sending information to one other device. It’s a one-to-one relationship,

A foundational knowledge of network architecture starts with the concepts of broadcast domains and collision domains. In this video, you’ll learn how modern network design has eliminated collision domains and how you can minimize the impact of broadcasts through the use of properly engineered broadcast domains. << Previous Video: Network Switching Overview Next: Unicasts, Broadcasts,

The network switch is perhaps the most common piece of networking equipment in use today. In this video, you’ll learn how the switch makes forwarding decisions, how the switch reacts when it doesn’t know the destination of a frame, and how the ARP command can be used to validate a switch’s forwarding table. << Previous

Ethernet is the most common network topology in the world. In this video, you’ll learn the fundamentals of how Ethernet communicates from one device to another and how half-duplex and full-duplex configuration can effect this data transfer. << Previous Video: Understanding the OSI Model Next: Network Switching Overview >> Here’s a picture of what the

The OSI model is one of the most common methods of describing application data flows. In this video, you’ll learn about the seven layers of the OSI model and how they are associated with real-world hardware and software components. << Previous Video: Common Ports Next: Introduction to Ethernet >> The OSI Model is the Open
