Many network engineers would love to move to working on a large enterprise networks, but to have the opportunity to do so takes education, experience, and dedication. This course, Layer 2 Switching and VLANs in Junos OS, along with the other courses in the JNCIS-ENT series, is designed to educate and prepare network engineers for working in enterprise environments. This course in particular begins with teaching you the basics which include Layer 2, switching and VLANs, and introduces Layer 3 switching in order to properly prepare you for the rest of the courses in this series. Next, you'll explore in-depth how to move data between VLANs. Finally this course will wrap up with teaching you how to continue, monitor, and troubleshoot Layer 2 switching. By the end of this course, you'll have the fundamental knowledge of Layer 2 Switching and VLANs to help continue your pursuit of working on large enterprise networks.

Course Overview
[Autogenerated] Hi, everyone. My name is Martin Brown. Welcome to my course layer to switching and villains in June. ____ OS I mean network security engineer for 81 service provider. Now networks have moved on considerably in recent years. They have become faster and bigger. They are now networks for the enterprise. In this course, we're going to look at switches designed for the enterprise environment, juniper X, serious switches and how they can move frames around the network quickly and reliably. Some of the major topics that we will cover include help Ethan. It has evolved how switches switch, what villains are and how to perform basic configuration on switches. By the end of this course, you'll be able to understand the basics of switch in and feel more confident in a plan of base configuration on Juniper PX. Serious Richards Although before beginning the course, you should really be familiar with the basics of the genius operating system. I hope you'll join me on this journey to learn all about switches with Jay. Answer Yes, TNT layer to switching and real and course at your site.

Configuring Switches Running Enhanced Layer 2 Software
[Autogenerated] In the previous video, we created villains on our new switch, which is running the here less software. In this video, we're actually going to start the sign imports to those villains. And in this video, what we going to do is actually going to create the trunk links that uses up link between switches between switch 23 the aggregation layer. So we need to ensure that traffic that's tagged with the 0.1 Q tag is able to pass between our switches. So we're going to set the follow imports as drunk ports. We're going to say G E 00 46 G E 00 47. Then we're going to make sure that only V Lens 102 100 controversies trunk minx. Then we're going to set the native bill and I d to 900. So this is what apology currently looks like. We're going to set G E 00 46 which goes to switch 23 is a trunk link. Then we're going to set G E 00 47 which goes to the aggregation. There also is a trunk link on the old switch 22 were actually use imports. 010 and 00 23 because this, which has a lot more ports, were just using the last parts on the switch. So let's go to a new switch and create these trunks bolts. And if we say that it then it interfaces. And it was g e 00 46 not zero. And let's have a look at how it's configured. You just says family, even its which in So it's part of the default beat. Okay, so the first thing we need to do is set the interface mode. Okay, so that's it. Family Ethan, It switching interface mode trunk. Okay. Their money to specify the villains that this port is part off. So set family, Ethernet, switching Phelan members and do square brackets engineering and sales. Okay, then finally we need to set the native villain I d to 900. If we go up, then say set native villain i d 900. And if we look at the configuration, you can see we've set the native villain I d under the main interface itself under the sub interface. Then again, we've set the interface motors, trunk and we've said it is part of the engineering in sounds feeling. Let's go and have a look at how it's configured on our old switch. So sure configuration interfaces G e 00 23. And as you can see to set the port type as trunk, we use the command port mode. Where is on the new switch? We use the command interface mode. In addition, the native Villain I D is set under Family Ethernet. Switch in. Where is on the new switch? You can see it set directly under the interface. So these air to changes that you need to be aware off if you're migrating from a switch running the standard software to a new switch running the here less software. So let's complete our task. The more configure Port 47 as well. And that's just clear the screen. And if I say up, then it g e. 00 47. Was it the native villain I D. First so sit native villain. I d 500. It it Unit zero sent family Ethan it switching interface mode, drunk set, family, Ethernet switching, villain members, engineering sales and show. So it's now set correctly. So let's just commit this and make sure it commits, okay? And if I say top exit, clear the screen and then say shoe the lens and you can see both 46 47 are part of Ile and 102 100. Okay, that's brilliant. So now we set our trunk ports. The next thing we need to do is a sign of excess ports to the relevant violence, and that's what we do in our next video.
