Basic Switch Configuration / LAB VLAN Setup
Subtitles of the Movie (Implementing Cisco IP Switched Networks (642-813 SWITCH) / Basic Switch Configuration / LAB VLAN Setup)
So in this section of the lab we are going to configure VLANs and then we'll configure VTP to push out those VLANs to all of our Client Switches. Now since the last lab, I have gone into all of our switches and given them Layer 3 addresses on the Default VLAN, VLAN 1. Now I've not done this because it's required, because VTP is a Layer 2 Protocol. However as part of the VTP verification tasks we'll be doing at the end of the lab, part of the Show VTP Status Screen shows us the IP address of the VTP Server that last updated our local VLAN database. And it's a lot easier to track down which switch is actually updating our VLAN database if we have an IP address that we can reference back to this guy. I've also made the Core Router our NTP Server for the entire subnet because some of the later sections of the course work better if you have time synchronized across all of the devices. So with all that out of the way, let's look at our Core 2 Switch. Now Core 2 is going to be our VTP Server, it's where we're going to define all of our VLANs and everything else is going to be a client. So just to show you there's nothing up my sleeve we'll do a Show VLAN on this guy first and you'll see that we have VLAN 1 set as the Default VLAN and all of the Switch Ports on the switch are in this Default VLAN except for our Trunk Ports, Fast Ethernet 01, 02 and 023. So I'm going to create three VLANs, VLAN 10, 15 and 20 and we're going to assign one port to each of these VLANs and then I'm going to set up VTP to push this VLAN Configuration information out. Now there are two ways to create a VLAN on a switch, if this is the VTP Server obviously. One way and this is probably the way most administrators do it, is they just go into the interface and assign it an Access VLAN and if that Access VLAN doesn't exist, it'll create it and the switch will actually tell you that. I think let's do that VLAN 10 and I'll show you what it looks like when you set up that way. So go into Config T, we'll do Interface Fast Ethernet 0 slash 10 and we'll do Switch Port Access VLAN 10. And it actually says Access VLAN does not exist, creating VLAN 10. So now if we exit out of this and we do Show VLAN at this point, it's created VLAN 10 with a very descriptive name of VLAN 0010 or VLAN 10. It says it's active and Port Fast Ethernet 010 is in this VLAN. Now we'll go ahead and create the other two VLANs and give them more descriptive names as well, as well as go in and, and rename VLAN 10 to something a little more descriptive. So we'll go into Config T and we'll do VLAN 10, we'll say name is going to be Sales. We'll exit out of this to get back out to Config Mode, you don't really have to do that on some IOS's but I like to do it because it's a cleaner configuration in, in my opinion. Do VLAN 20, we just created VLAN 20 so now we can give it a name of Marketing and then exit out and do VLAN 15 and give it a name of Research. So now that those three VLANs are configured, we'll do Show VLAN and there are our three VLANs that we've got set up. There all three active but only one of them has a port assigned to it. Now we can easily go and fix that just like we did with the Fast Ethernet 010. We just go into the Config Mode, Interface Fast Ethernet 0 slash 15, Switch Port Access VLAN 15 and you notice we didn't get the message this time that said it was creating it, because it already existed. And we'll do Switch Port 20 and change this Access VLAN to 20 there. Now if we do Show VLAN we have all three VLANs set up, there all three active and they all three have one port in them. And that one ports going to come into play when we discuss cleaning up the VLANs and VTP Pruning elsewhere in the course. Now that we've verified that, that's all good, let's do a Show VTP Status, just to see what VTP says right now. Right now you see that we are running VTP Version 1, we are capable of running everything from VTP Version 1 to 3 because of the type of switch we're on. This is a 3560 switch running the latest IOS available as of early 2012. You'll notice here's those IP addresses that I mentioned. Obviously the last configuration modification was done by this IP and that's us, that's our IP address. You can see that we're configured as a VTP Server, we have eight existing VLANs counting all of the built in Token Ring and FDDI and et cetera et cetera and we're on configuration revision 16 because I've gone through this lab a few times in, in preparation for this. However since all of the devices on the network are configured as VTP Servers, if we go over here to Core 1 for example, if we do Show VLAN, you notice our VLANs have not synchronized over here. Do Show VTP Status, the reason why is that it's considers itself a server with no VTP Domain Name and so it's going to say, well you know, I am a server so I'm not going to accept any updates from you, this Core 2 Switch. Because everything's all null, it's running as default and obviously this is working by design. You don't want VLAN information to be pushed out to all of the other switches without you actually going in and specifically saying I want you to configure this VLAN Domain Name and this VTP Password and all this other stuff like that in a more planned and controlled manner. We're actually going to set all of the VTP up in the next video.
