what's up guys welcome back to the
channel i'm mike this is the ultimate
tech hub thank you for joining me i
really appreciate it
you guys are awesome so today we're
going to talk about vlans and i'm going
to fully explain what a vlan is and how
it's used first what is a vlan a virtual
local area network so what do vlans do
well there's three main things that vlan
does
first it improves security
second traffic management and third
makes your network simpler and whether
you have a business or a home network a
vlan is a great choice to manage your
network traffic for instance almost all
businesses use vlans
to separate departments within a network
however you could separate these
departments physically
by putting all the computers in one area
and setting up additional hardware
but that costs money
and time
so the best way to do this
is to separate the departments by vlans
virtual local area networks so what does
a vlan do
well a vlan isolates traffic within a
network
and vlans are created on a switch by
assigning specific ports to a specific
vlan
for instance port 1 will go to vlan 10.
port 2 goes to vlan 10 port 3 vlan 10
now port 4 will go to vlan 20
and on and on there is no limit to how
many ports you can assign to a vlan the
only limit is the number of ports on
your switch and vlans are created on
layer 3 switches however your home
router also has this capability
and setting up vlans for your home is
also very important
[Music]
my recommendation is to set up a vlan
for your iot devices like lights
thermostats
appliances and if you have a home office
like we do definitely put that on a
separate vlan
you can and should treat your home
network like a business network simply
separate your house into small
departments and there's no limit to the
amount of ports you can put on a vlan or
the amount of vlans you can create and
remember traffic management is the
number one reason we use vlans
so remember vlans divide out the network
into smaller broadcast domains which in
turn helps alleviate broadcast traffic
and congestion and vlans improve
security and lastly vlans make your
network simpler
so now get out there and create vlans
for your home network it's easy
and guys if you made it this far thank
you so much for watching i really
appreciate it
