Congfiguring VLANs

To configure VLAN we will use the following topology
Topology overview: Laptop_1, Laptop_2, Laptop_3 and Laptop_4 are connected to Switch_1 on port f0/6, f0/7, f0/8 and f0/9 respectively.
f0/5 on Switch_1 which is connected to Switch_2 on f0/13 would be the trunk port.
Laptop_5, Laptop_6, Laptop_7 and Laptop_8 are connected to Switch_2 on port f0/9, f0/10, f0/11 and f0/12 respectively.





These are the commands to configure VLAN for Switch_1

  

Switch>enable
Switch#configure terminal
Switch(config)#hostname Switch_1
Switch_1(config)#vlan 20
Switch_1(config-vlan)#do show vlan

 

Switch_1(config-vlan)#name IT
Switch_1(config-vlan)#do show vlan

Switch_1(config-vlan)#exit
Switch_1(config)#vlan 30
Switch_1(config-vlan)#name HR
Switch_1(config-vlan)#do show vlan

Switch_1(config-vlan)#exit
Switch_1(config)#interface fastEthernet 0/6
Switch_1(config-if)#switchport mode ?

Switch_1(config-if)#switchport mode access
Switch_1(config-if)#switchport access vlan 20
Switch_1(config-if)#exit
Switch_1(config)#interface fastEthernet 0/7
Switch_1(config-if)#switchport mode access
Switch_1(config-if)#switchport access vlan 20
Switch_1(config-if)#interface fastEthernet 0/8
Switch_1(config-if)#switchport mode access
Switch_1(config-if)#switchport access vlan 30
Switch_1(config-if)#interface fastEthernet 0/9
Switch_1(config-if)#switchport mode access
Switch_1(config-if)#switchport access vlan 30
Switch_1(config-if)#do show vlan

Switch_1(config-if)#end
Switch_1#show interfaces trunk
Switch_1#configure terminal
Switch_1(config)#interface fastEthernet 0/5
Switch_1(config-if)#switchport mode trunk
Switch_1(config-if)#end
Switch_1#show interface trunk

These are the commands to configure VLAN for Switch_2

Switch_2(config)#configure terminal
Switch_2(config)#vlan 20
Switch_2(config-vlan)#name IT 
Switch_2(config-vlan)#exit 
Switch_2(config)#vlan 30 
Switch_2(config-vlan)#name HR 
Switch_2(config-vlan)#exit 
Switch_2(config)#interface fastethernet 0/9 
Switch_2(config-if)#switchport mode access 
Switch_2(config-if)#switchport acces
Switch_2(config-if)#switchport access vlan 20 
Switch_2(config-if)#interface fastethernet 0/10 
Switch_2(config-if)#switchport mode access 
Switch_2(config-if)#switchport access vlan 20 
Switch_2(config-if)#interface fastethernet 0/11
Switch_2(config-if)#switchport mode access 
Switch_2(config-if)#switchport access vlan 30 
Switch_2(config-if)#interface fastethernet 0/12 
Switch_2(config-if)#switchport mode access 
Switch_2(config-if)#switchport access vlan 30 
Switch_2(config-if)#interface fastethernet 0/13
Switch_2(config-if)#switchport mode trunk
Switch_2(config-if)#do show vlan

Final output : after configuring both switches provide IP addresses to all laptops as shown in the topology. and you should be able to ping into same VLAN. you shouldn't be able to ping between VLANs because we havn't yet configured inter vlan routing.
