VLAN Configuration

Configure VLAN with Cisco Switch

A VLAN is a switched network that is logically segmented by function, project team, or application, without regard to the physical locations of the users. Any switch module port can belong to a VLAN, all  packets are forwarded and flooded only to end stations in the VLAN.

Range of VLANs
Normal-range VLANs are VLANs with VLAN IDs 1 to 1005. You can  add, modify or remove configurations for VLANs 2 to 1001 in the VLAN database. (VLAN IDs 1 and 1002 to 1005 are automatically created and cannot be removed.)
VLAN also breaks the collision doamin to increase network performance.

You can set these parameters when you create a new normal-range VLAN

•VLAN ID
•VLAN name
•VLAN type (Ethernet, Fiber Distributed Data Interface [FDDI],

Configure VLAN on Switch 1 
 First of all create VLANs that you needed then attach ports with  appropriate VLANs. 
Here is a sample how to create VLAN on Cisco switch. In example i have created two VLANs named as mkt (id 3) and sales (id 2).

Use #show vlan  to verify vlan configuration on privilege mode.
Now systems that are associated with same VLAN name and ID  will be able to communicate with each other, in above example  sales1 and mkt1 will not be able to communicate to each other due to different VLANs.
