VLAN creation on cisco packet tracer.

VLAN creation on cisco packet tracer. 1.    We will discuss in this lesson about VLAN. What is its purpose and why do we create it?    2.      VLAN stands for virtual local area network that means we can divide resources virtually in different type of tasks. For example, in a company there are three department HR, ADMIN and IT department. All resources connected to each other in single LAN by physically, but we can divide them into three VLANs which will be separately for each department.   3.    Let’s understand with practical way. In this below picture we have taken one router, one switch and 6 PCs. We will assign each two PC in different VLANs.  4.    Put Unique VLAN ID for each Department like vlan 10 for HR, vlan 11 for ADMIN and vlan 12 for IT Department. Assign IPs to each PC according to given in the picture. As I have put on PC0.      5.    As you can see on above picture, I have put IP for PC0 192.168.1.10 and default gateway for this 192.168.1.1 Its mean default gateway will be 192.168.1.1, 192.168.2.1 and 192.168.3.1 for each Department HR, ADMIN and IT. IPs will be next network host like 192.168.1.2 192.168.1.3 and so on ….          6.     In next step we will configure VLAN on switch, Kindly follow below configuration Switch>en Switch#config t Switch(config)#vlan 10 Switch(config-vlan)#name HR Switch(config-vlan)#exit Switch(config)#vlan 11 Switch(config-vlan)#name ADMIN Switch(config-vlan)#exit Switch(config)#vlan 12 Switch(config-vlan)#name IT Switch(config-vlan)#exit Switch(config)# 7   7.    Further step we need to assign switch ports as access or trunk. So ports F0/1 to F0/6 will be access because they will carry single VLAN data and port F0/7 will be trunk because it carries all VLAN data. Follow below configuration to assign ports to particular VLAN. Switch> Switch>en Switch#config t Switch(config)#int range f0/1-2 Switch(config-if-range)#switchport mode access Switch(config-if-range)#switchport access vlan 10 Switch(config-if-range)#exit Switch(config)# Switch(config)#int range f0/3-4 Switch(config-if-range)#switchport mode access Switch(config-if-range)#switchport access vlan 11 Switch(config-if-range)#exit Switch(config)#int range f0/5-6 Switch(config-if-range)#switchport mode access Switch(config-if-range)#switchport access vlan 12 Switch(config-if-range)#exit Switch(config)# Switch(config)#int f0/7 Switch(config-if)#switchport mode trunk Switch(config-if)#switchport trunk allowed vlan 10 Switch(config-if)#switchport trunk allowed add vlan 11 Switch(config-if)#switchport trunk allowed add vlan 12 Switch(config-if)#                       8.     Go to router and need to configure below for further steps. Router>en Router#config t Router(config)#int f0/0 Router(config-if)#ip address 192.168.1.1 255.255.255.0 Router(config-if)#no shut Router(config-if)#exit Router(config)#int f0/0.1 Router(config-subif)#encapsulation dot1Q 11 Router(config-subif)#ip address 192.168.2.1 255.255.255.0 Router(config-subif)#no shut Router(config-subif)#exit Router(config)#int f0/0.2 Router(config-subif)#encapsulation dot1Q 12 Router(config-subif)#ip address 192.168.3.1 255.255.255.0 Router(config-subif)#no shut Router(config-subif)# 9.      Now you can try ICMP packets can be sent. As below in the picture. 10.  Kindly put comment on comment box below for suggestion or concern.
