In today’s computer networks, switches are super important. They help PCs talk to each other really well. Thus, switches use MAC addresses to send data packets.
In this article, we’ll look at how a switch works. We’ll see how they learn MAC addresses. Also, we’ll check out network packets using GNS3 and Wireshark.
The Spanning Tree Protocol (STP) in computer networking stops loops in the network setup. It’s vital for keeping the network stable and preventing broadcast storms. It works by specifying a single “root” bridge and then turning off connections that might cause loops. So, STP is a protocol we commonly use. However, it can be a little tricky to configure.
In this article, we’ll show you how to configure the Spanning Tree Protocol on a Layer 2 Switch. We’ll use GNS3, a network simulation tool, to do it. We’ll look at essential features like PortFast, BPDU guard, and root guard. After that, we’ll show you how to set it up to work with VPCS computers.
When we configure the Spanning Tree Protocol on Cisco Switches, we usually use the spanning-tree vlan priority command when selecting Root Bridge Switch.
When configuring the Standard Spanning Tree Protocol, we often encounter terms such as UplinkFast, PortFast, and BackboneFast. However, these features are specific to the Cisco brand only and cannot be used with other brands.
When we configure the standard Spanning Tree Protocol on Layer 2 Switches, the STP Convergence process takes 50 seconds as a result of a link error. We can reduce this downtime with UplinkFast (UF) up to 20 seconds.
Today, lots of companies use computer networks a whole bunch. The folks who manage these LANs have to make sure they’re fast, dependable, and safe. One way to do this is by setting up switches with the Spanning Tree Protocol (STP).
When a switch port breaks and causes STP to stop working, it can be a big issue. PortFast helps fix this. In this guide, we’ll explain how to enable and configure PortFast on a Layer 2 switch using GNS3.
Are you curious about setting up a Layer 2 Switch as the Root Bridge in your network on GNS3? Usually, devices sort out the Root device using a Spanning Tree. But we can set it manually on Cisco Switches. How? We check out MAC addresses, Priority values, and Cost values.
But sometimes, it’s a good idea to pick the Root Switch ourselves. So, in this article, we’ll choose a Switch manually using the Priority value. Let’s begin!
In computer networks, the Spanning Tree Protocol (STP) stops loops. In this article, we’ll look at how STP works on Layer 2 Switches with GNS3.
We’ll explore the selection of Designated, Root, and Blocked Ports. Plus, we’ll go over setting up STP and analyzing packets with Wireshark. If you want to know more about this protocol, keep reading!
In this article, we will examine how to enable Port-Security on Layer 2 Switch in the Network Simulator software.
In this article, we will create VLAN and configure Inter-VLAN routing on the Cisco L2 Switch using the Graphical Network Simulator program.
In this article, we will examine the steps of configuring Cisco Switch on a small network topology with Graphical Network Simulator-3.
