You can gain experience by designing network topologies on GNS3 or use IOS images of real Cisco devices. By adding IOU devices to your network project, you can use the Cisco Layer 2 Switch and Layer 3 Switch.
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.
To use Cisco L2 and L3 images on GNS3, you need to configure IOU.
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 come across terms such as UplinkFast, PortFast, and BackboneFast. These features are specific to the Cisco brand only, and they cannot use with other brands.
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 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 Graphica Network Simulator program.
