What is VLAN (Virtual Local Area Network)?

Last Updated: |

In modern network infrastructure, VLAN (Virtual Local Area Network) plays a vital role in organizing data traffic. It also ensures that networks operate more efficiently and effectively. The VLAN network developed by IEEE functions at OSI Layer 2. In short, we use this technology to separate our physical networks into logical networks.

If I clarify my statements, VLAN creates non-physical networks. As a result, we facilitate the organization and management of networks. In this professional article, I will describe exactly what virtual LANs are and their basic concepts.

How to Install Cisco SDM (Security Device Manager)

Last Updated: |

Cisco SDM (Security Device Manager) makes it simple to care for Cisco Routers through a graphical user interface. This program, created by Cisco, works on the web and is strong. You can install Cisco SDM on a physical computer or a virtual machine. With this program, you can set up the safety stuff for devices in your network using ACL (Access Control List). Also, you can make special networks like VPNs and improve your network.

You can also access the user interface using a web browser and start a step-by-step guide to set things up. Furthermore, this program for managing routers gives you a cool Cisco AutoSecure feature.

Cisco Router Boot Process Steps

Last Updated: |

We need to know and understand the process of booting a Cisco Router in the network. This information is vital, especially for us network administrators and IT professionals. Also, if we know the stages of the boot process, we can solve problems better and efficiently.

In this article, I will clarify the stages of the boot process step by step. In short, the first stage is the POST test. After that, the routing device finds and loads the IOS. Then, the configuration file comes into play and loads the settings. Let’s literally get started and explore the details!

What is a Router? | Features, Types, & How Do Routers Work?

Last Updated: |

Routers play a critical role in data transmission in structures we call networks. In short, they provide efficient communication between these networks. Therefore, if we understand the working principles of routers better, we will be able to increase our LAN performance. In addition, these devices use routing protocols while managing data packets. As a result, they form the backbone of modern networks.

In this article, I will tell you exactly what a Router is in computer LANs and how it works. I will also examine routing mechanisms and tables. In short, it does not matter if you are at the entry level of networking; I hope you will understand it.
