What is VLAN? Advantage of VLAN and configuration VLAN?

Hello... Friends Welcome to my tutorial
My name is Dinesh Kumar Gupta. friends in the tutorial we learnt about that

What is VLAN?

VLAN:- Stands for Virtual Local Area Network
that is used to divided Single Broadcast  Domain into Sperate Broadcast Domain.
Is called VLAN.
Basically, VLAN concept related to the switch and we know that in a switch has multiple ports.
So here we can create are VLAN  1-1005 (Range of VLAN 1-1005)
and the VLAN 1, 1002, 1003, 1004, 1005 is default VLAN
VLAN 1 called is the default VLAN and know as Native VLAN, Administrative VLAN
And remember that all the switch port are in VLAN 1.

Advantage of VLAN

• Limit the Broadcast
• Increase the Security
• Simple Management
• Increase the Network performance
• Scalable and flexibility

Now let's understand that how to create VLAN in Switch  at first, always remember that all the configuration run on the global configuration mode. so here is command is

Switch>

Switch>enable

Switch#configure terminal

Switch(config)vlan 10

And we can see the VLAN command is

Switch#show vlan

And after that, we learnt how to assign the port in VLAN

as you can see that we already create VLAN 10, VLAN 20

now I'm  going to assign the port in VLAN and also you can see all port are in by default in VLAN 1

command is

Switch(config)#interface f0/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10
Switch(config-if)#exit

Show the vlan 

we can assign the port for VLAN with a range
first, select the interface with the range
command is 

Switch(config)#interface range f0/1-2
Switch(config-if-range)#switchport access vlan 10
Switch(config-if-range)#exit
