Wireless networks include a number of different technologies. In this video, you’ll learn about wireless frequencies and channels, band steering, and regulatory impacts. << Previous: Spanning Tree Protocol Next Video: Wireless Networking >> We’ve become so accustomed to wireless networks being available that we often forget that there’s a lot of work that happens behind […]

One challenge with switching is the concern of network loops. In this video, you’ll learn how Spanning Tree Protocol (STP) can be used to prevent loops and recover the network if an outage occurs. << Previous: Interface Configurations Next Video: Wireless Technologies >> If you had two switches and you connected them together with an

There are different configuration options to consider when connecting to an Ethernet network. In this video, you’ll learn about interface settings, link aggregation, MTU sizes, and jumbo frames. << Previous: VLANs and Trunking Next Video: Spanning Tree Protocol >> When you’re configuring a router interface, a switch interface, or an interface that’s in your local

VLANs can be used to create a separate of broadcast domains on a single switch. In this video, you’ll learn about VLANs, 802.1Q trunking, and managing both voice and video across the same connection. << Previous: Network Address Translation Next Video: Interface Configurations >> As a very broad description, a local area network, or a

Network Address Translation is used to modify IP addresses in real-time. In this video, you’ll learn how NAT and NAT overload/PAT are used to minimize the use of public IP addresses. << Previous: Routing Technologies Next Video: VLANs and Trunking >> There are many devices connected to the internet. Some estimates are 20 to 30

There is a lot of information contained in a routing table. In this video, you’ll learn about the details in a routing table, FHRP, and subinterfaces. << Previous: Dynamic Routing Next Video: Network Address Translation >> The job of a router is to evaluate incoming traffic, determine what the destination might be for that traffic,

Routing tables can be configured automatically through the use of dynamic routing protocols. In this video, you’ll learn the mechanics of dynamic routing protocols and the most popular dynamic routing protocols. << Previous: Static Routing Next Video: Routing Technologies >> Static routing requires the network administrator manually configure every route on every router in the

Router tables can be manually configured using static routes. In this video, you’ll learn about routing tables, static routes, and how to define a static route in a router. << Previous: IPv6 Addressing Next Video: Dynamic Routing >> The routers that we use in our homes and our offices have an important job of forwarding
