2. What is the difference between VLAN and Subnetting?

VLAN

Works at the data-link layer. It is based on switch configuration.

Subnetting

Works on the network layer. It is based on IP addressing.

3. Create a switch with 5 PCs. Create 2 VLANs and assign 2 PCs to 1 VLAN and another 3 PCs to another VLAN. Create different networks for the VLAN and test the connection.

Create a VLAN:

enable
configure terminal
vlan <vlan number>
name <name of vlan>
exit

Assign ports to the VLAN:

enable
configure terminal
interface <interface id>
switchport mode access
switchport mode <vlan id>

Assign a range of ports to the VLAN:

enable
configure terminal
interface range <interface id range>
switchport mode access
switchport mode <vlan id>
