Switch(config-vlan)#exit

Assign Switch Port to Access VLAN

Switch#configure terminal

Switch(config)#interface FastEthernet0/2
Switch(config-if)#switchport mode access                     //assign switchport for only one vlan

Switch(config-if)#switchport access vlan 2                    //assign vlan in switchport

Switch(config-if)#exit

VLAN type: show vlan command show a list of vlan in my switch. Where VLAN 3 and VLAN 2 was created manually. Other VLAN 1 and VLAN 1002-5 was exist by default. So we can create vlan from 2 to 1001 and
1006 – 4094. Where VLAN 2 to 1001 is normal range and VLAN 1006 - 4094 is extended range.

VLAN Mode: VLAN have two mode access mode and trunk mode.
Access Mode: In Access Mode a port use for single vlan data transmission. Data transfer without VLAN tag.

Trunk Mode: In Trunk mode multiple vlan use same port for data transmission. Data transfer by individual VLAN tag.
