Lab 11‐1: VLANs in Packet Tracer Part 1 - sthompson2752/Network-Fundamentals GitHub Wiki

This lab used Packet Tracer to introduce the concept of VLANs and how they affect pinging devices.

Useful Instructions: Use crossover cables when connecting switches. Devices on the same VLANs have connected IPs, not the ones connected to the same switch. VLANs are on differing LAN but act like they are on the same wire. VLANs work in layer 2 network (routers determine broadcast domain) Access ports only assigned one VLAN, trunk uses all

Creating VLANs on a switch: Navigate to the config tab of the switch that is being used to create VLANs. Click on the VLAN database. Input the VLAN number (can be any number except 0 and numbers already used). Input the VLAN name (make this a name that makes the VLAN easily recognizable). Click add. Do the same as above for the remaining switches.

Configuring an interface as an Access port: Make sure the interface is set as Access. Go to the interfaces that are to be used on the switch and click the VLAN number that is needed (the device that will be connected to that interface will use that VLAN). Access ports will be used for interfaces connecting to end devices (at least for this lab).

Configuring an interface as a Trunk port: Change the interface to be set as Trunk. Check that all of the VLANs are clicked on. Trunk ports will be used for interfaces connecting to other switches (at least for this lab).

The concept of VLANs makes sense to me so far, although I know as I deepen my learning I may come across some confusion. At first I tried to use the wrong cables when connecting the switches. I then read further down in the instructions that crossover cables needed to be used. Other than this small bump, the lab was very easy for me.
