Now unfortunately the font of the switch is very small and doesn't wanna change I'll zoom in on the
video.
The core switch has a large font
and even though I change the font via options, preferences, font and I've set it to a large number
these 2960s I'm not changing their font.
So I'll simply zoom in on the video.
So my apologies if the resolution isn't that great when I configured these switches but on this access
switch what we need to do is we need to configure interface gigabit 01 as a trunk port, so switch port
mode trunk, that's come up but again don't forget that sometimes you have to specify the encapsulation.
The switch doesn't allow you to specify the encapsulation it only supports dot1q so show interface
gigabit
01 switch port shows us that the encapsulation used is a dot1q. So that's the encapsulation
that we're looking for the port is enabled and it's a trunk port. So show VLAN
notice we're only seeing VLAN 1 in the VLAN database show VTP status shows us that the switch is a server
number of VLANs in the VLAN database is 5 typically a switch would learn the VLANs from the
core switch.
So this port is a trunk port by default all VLANs will be permitted the switch is not learning the VLANs.
Now if you wanna use VTP to distribute VLANs what you need to do is set the VTP domain.
At the moment there is no domain name configured.
So what we could do is say VTP domain and specify a domain such as CCNA.
So now show VTP status shows us that the VTP domain name is CCNA, show VLAN shows us that we've got
our VLANs in the VLAN database and then if we have a look on switch one, the access switch show VLAN
shows that we still only have VLAN 1 and the other default VLAN on a real switch.
The switch would learn and notice it has learnt that.
So show VLAN
and the switch in turn would learn the VLANs.
So show VLAN here.
We still have our VLANs in the VLAN database on this access switch hasn't learned the VLAN.
I'll set the mode to VTP client to see if that makes it any better.
I notice now it's learnt the VLANs. In the real world
a switch would learn the VTP domain like packet tracer did here but a server would still synchronize
with another server so the switch would have learnt the villains even if it hadn't been a client. In
the exam they would be clearer about what to do with your VLANs so that would either tell you to
create them manually or to use VTP to create the VLANs. So switch 1 has now learnt the VLANs.
The next step is to go into forced Ethan at 0 1 and type switch port mode access switch port access
VLAN in this case 10. Interface VLAN 1 the switch needs to have a IP address of 10.1.
1
.1 configured on it. I'll no shut the VLAN
so at this point it will hopefully be able to ping the core switch in the topology which it can,
so that's great.
The last thing you need to do is specify default gateway of 10.1.1.254, so the switch
should now be able to ping IP addresses in other VLAN on the core switch which it can.
So again configuration was to set the VLAN to VLAN 10 on the access port we have to configure trunking
on the link to the core we configured a SVI an IP address on the SVI and we configured a default gateway
so that's switch 1 configured.
Now we need to do something similar on switch 2 and switch 3.
