What is VPN? What Does It Do?

VPN (Virtual Private Network) allows you to create a secure connection to another network over the Internet. When you connect any device to a VPN, it acts as if it is on the same network as the VPN and all data traffic is sent securely over the VPN.

What is RSTP (Rapid Spanning Tree Protocol – 802.1W)?

RSTP (Rapid Spanning Tree Protocol) is like an intelligent helper for the network. It stops loops and works faster than the older STP. This protocol makes sure devices adjust quickly to changes in the LAN. It keeps things running well, making sure everything is available and works smoothly. That’s why many experts like using it. In this article, we’ll check out what RSTP is, its excellent features, and how it works in networking.

The Standard Spanning Tree Protocol prevents network loops on Cisco Switches (802.1D). If there’s a link or cable problem, it figures out the best route for the packet to reach its destination.

Spanning Tree Show Commands | A Guide for Network Professionals

In a network, the spanning tree protocol (STP) is super important. It stops loops, which can mess up things like broadcast storms. It uses clever math to create a loop-free setup for Ethernet networks. To keep an eye on it, network admins use different show commands. In this article, we’ll check out some common show commands that tell us about the STP protocol setup and how it’s doing.

After configuring the Spanning Tree Protocol, which is usually configured on Layer 2 Switches, it may be necessary to verify the settings made. When configuring Cisco Switches, we typically use the CLI command prompt.

What is Uplinkfast in Spanning Tree Protocol? | How It Works?

If you’re into networking, you’ve probably heard of the “Spanning Tree Protocol.” It helps make a loop-free setup in a switched Ethernet network. To make it work even better, there are features like UplinkFast. In this article, we’ll see what UplinkFast is and how it works in the Spanning Tree Protocol. Let’s dive in!

The STP protocol was developed to prevent loops in the OSI model layer 2. In a cable failure that occurs in a redundant network, several features have been created due to the high STP Convergence time.

What is Portfast in Spanning Tree Protocol? | Understanding How It Works

If you know a bit about networks, you might have come across something called Spanning Tree Protocol (STP). It’s a protocol that stops network loops by letting switches talk and pick a root bridge. Now, one cool thing in STP is Portfast. This helps make a switch port go from blocking to forwarding state faster. It’s a handy tool to make your network work better. But what exactly is Portfast, and how does it work? Let’s check it out.

When you connect a computer or server to the switch port, it can join the network and talk to other devices. But sometimes, loops happen on the network. That’s why we use the STP protocol to stop them.

The Port States & Roles of Spanning Tree Protocol (STP and RSTP)

If you’re using network switches, it’s super important to know about STP (Spanning Tree protocol) and its port states. In simple terms, STP makes sure there are no loops in the network, keeping things stable even if something goes wrong. When a switch does its job, it uses essential parts called port states. In this article, we’ll look at the different port states and roles of STP & RSTP and how it takes care of the network setup.

When you turn on a switch, each of its ports (connections) goes through four steps. Blocking, Listening, Learning, and Forwarding are the port states. There’s also a fifth step, known as the Disabled state.
