VLANs and Trunks for Beginners - Part 2

so so far we have VLAN 1 which is also known as the default VLAN we've got VLAN 50 right here which we named student right and this VLAN 50 is actually what we would call a data VLAN so here I've got the types of VLANs over here default VLAN data via LAN right and we created another VLAN we created a VLAN for management at VLAN 99 so we've got a V land that we can use for management let's say at VLAN 99 and we've set that up to be we named it management and we're going to use it for management and I'll talk about that a second here so we've got VLAN 1 VLAN 50 right and what we'll do is we'll pull out another PC and this PC will put on the VLAN 99 which were reserving for management I'll just say MGT there right so I'll get a cable straight through cable I'll cable it to this PC I'll cable it to the switch at the last port let's say 24 for our manager and I'm gonna put this one on say one nine two one six eight dot 99.1 hundred notice how I'm making the networks match the number of the VLAN now you don't have to do that but it's helpful in kind of remembering what you're doing what VLAN you're on will now correspond with the network number right of the network and so that's helpful and so what I'll do is take this PC and I'll set his IP address to be that all right so now this pc is going to be on the 99 Network now we still have to assign that port on the switch to that VLAN so what we'll do is we will do a conf T int which is short for interface FA 0/24 got change that to a zero and then I'll say SW tab switch port mode access and then switch port access VLAN 99 okay now if we do a ctrl C and then do a show VLAN you can see that there's the management VLAN VLAN 99 now port 24 is on it now our PC is on that port now what's important about the management VLAN is the management VLAN is the VLAN that let's say a manager an administrator could remote into the switch to administer the switch or to manage the switch right so by remoting into the switch what we mean is we mean possibly using telnet insecure or SSH to remotely manage the switch and that means the switch needs an IP address well since we have the VLAN 99 which is our management VLAN this is going to be the VLAN that we set up with an IP address so that this PC is able to communicate with the switch and remote into the switch so what we'll do is we'll click on the switch right now the switch doesn't have an IP address so you can't communicate with the switch so we'll say conf T to get to global config mode and we'll say int tab interface VLAN 99 and that puts us into interface VLAN 99 now this interface is an interface for the VLAN 99 which is set up so that you can give the switch an IP address so that you can basically manage the switch so now what we can do is now that we are in interface VLAN 99 which essentially is a virtual interface it's not a port on the switch it's not an actual plug in port this is a a virtual interface and what we'll do is we'll say IP address say 192.168.20.10 or something like that and I need to put a dot in between those so I give it I P address IP space address space one 92168 92169 we could try to ping that address and if we can ping that address we can probably tell that into it if we've configured the virtual telnet virtual terminal lines that that we could use for telnet so let's for just try to ping it first and we'll attempt a ping now okay we got a timeout but then we got replies right so we are able to communicate with ninety 9.2 and why is that it's because we're 99.1 hundred we're on the same network right we're on VLAN 99 and interface VLAN 99 has the IP address so this is a communication so now we've got the default VLAN covered which we know is VLAN 1 by default you can't get rid of it can't change the name you've got a date of eel and VLAN 50 which is used just for moving data for all your users connecting to the switch right we've got a management VLAN which is the VLAN that's going to have the IP address set on it right so we have the management VLAN so now what we need to talk about is the native VLAN and a voice VLAN now the CCNA curriculum barely talks about voice VLANs voice over IP and voice VLANs are just barely addressed in the curriculum a little bit but the native VLAN in this chapter is a lot more important native VLAN is important when we start talking about trunk ports right now these are all access ports they have VLANs on them but their access ports one VLAN per port right when you talk about a trunk port you talk about a port that can carry multiple VLANs across one link and so that's what we're going to talk about next
