How to Configure VLAN in Cisco switch

VLAN is Stand for Virtual LAN. It means device  logically divided in to different -2 LAN . Its improve security and reliability of your network. Switch create logical broadcast domain to each VLAN.

VLAN Creation in Switch 1

switch1>en
switch1#conf t
switch2#vlan database
switch1(vlan)#vlan 10
VLAN 10 added:
    Name: VLAN0010
switch1(vlan)#vlan 20
VLAN 20 added:
    Name: VLAN0020
switch1(vlan)#exit
APPLY completed.
Exiting....
switch1#

Assign IP address to the VLAN

switch1>en
switch1#conf t
switch1(config)#int vlan 10
switch1(config-if)#ip add 192.168.1.1 255.255.255.0
switch1(config-if)#no shut
switch1(config-if)#exit
switch1(config)#int vlan 20
switch1(config-if)#ip add 192.168.2.1 255.255.255.0
switch1(config-if)#no shut
switch1(config-if)#exit
switch1(config)#exit

Assign Port to the VLAN

switch1#conf t
switch1(config)#int f0/2
switch1(config-if)#switchport mode access 
switch1(config-if)#switchport access vlan 10

switch1(config-if)#int f0/3

switch1(config-if)#switchport mode access

switch1(config-if)#switchport access vlan 10
switch1(config-if)#int f0/4
switch1(config-if)#switchport mode access
switch1(config-if)#switchport access vlan 20
switch1(config-if)#int f0/5

switch1(config-if)#switchport mode access

switch1(config-if)#switchport access vlan 20

Show VLAN INFORMATION

switch1#sh vlan

VLAN Name                       Status    Ports
---- -------------------------------- --------- -------------------------
1    default                     active    Fa0/1, Fa0/6, Fa0/7Fa0/8
                                           Fa0/9, Fa0/10, Fa0/Fa0/12

                                           Fa0/21, Fa0/22, Fa0/23, Fa0/24
                                           Gig1/1, Gig1/2
10   VLAN0010                    active    Fa0/2, Fa0/3
20   VLAN0020                    active    Fa0/4, Fa0/5

VLAN Creation in Switch 2

switch2>en
switch2#conf t
switch2#vlan database
switch2(vlan)#vlan 10
VLAN 10 added
    Name: VLAN0010
switch2(vlan)#vlan 20
VLAN 20 added:
    Name: VLAN0020
switch2(vlan)#exit
APPLY completed.
Exiting....

Assign IP address to the VLAN

switch2>en

switch2#conf t
switch2(config)#int vlan 10
switch2(config-if)#ip add 192.168.1.1 255.255.255.0
switch2(config-if)#no shut
switch2(config-if)#exit
switch2(config)#int vlan 20
switch2(config-if)#ip add 192.168.2.1 255.255.255.0
switch2(config-if)#no shut
switch2(config-if)#exit

Assign Switch Port to VLAN

switch2#conf t
switch2(config)#int f0/2
switch1(config-if)#switchport mode access
switch2(config-if)#switchport access vlan 10
switch2(config-if)#int f0/3
switch1(config-if)#switchport mode access
switch2(config-if)#switchport access vlan 10
switch2(config-if)#int f0/4
switch1(config-if)#switchport mode access
switch2(config-if)#switchport access vlan 20
switch2(config-if)#int f0/5
switch1(config-if)#switchport mode access
switch2(config-if)#switchport access vlan 20
switch2(config-if)#exit

Show VLAN information in switch 2 

switch2#sh vlan

VLAN Name                       Status    Ports
---- -------------------------------- --------- -------------------------
1    default                     active    Fa0/1, Fa0/6, Fa0/7Fa0/8
                                           Fa0/9, Fa0/10, Fa0/Fa0/12
                                           Fa0/13, Fa0/14, Fa0/15, Fa0/16
                                           Fa0/17, Fa0/18, Fa0/19, Fa0/20
                                           Fa0/21, Fa0/22, Fa0/23, Fa0/24
                                           Gig1/1, Gig1/2
10   VLAN0010                    active    Fa0/2, Fa0/3
20   VLAN0020                    active    Fa0/4, Fa0/5

                

In this information port Fa0/2 and Fa0/3 are define for VLAN 10 , and Port  Fa0/4 and Fa0/5 are define for VLAN 20
