Steps To Create VLAN
1. Vlan Database
2. Access Mode
3.Trunk Mode
Step 1:
Vlan Database
- Collection of VLAN information
- Vlan No. Starts from 1 to 1005
- Vlan No.1 is a default Vlan
- Vlan No.2 to 1001 is a management Vlan
- Vlan No.1002 to 1005 is a reserved Vlan
Syntax to create a Vlan Database
- Switch>enable
- Switch#vlan database
- Switch(vlan)#vlan <no> name <anyname>
- Switch(vlan)#exit
To verify Vlan Database
- Switch#show vlan brief
Step 2:
Access Mode
- Connection between Switch to End devices
- Bandwidth in 10 or 100 Mbps
- By default all Ports are Member of Vlan 1
- It Carry single Vlan information
End Devices --> PC, Server, Ip phone, Camera, Printer,
Syntax to create Access Mode
- Switch>enable
- Switch#config t
- Switch(config)#interface fastEthernet <port no>
- Switch(config-if)#switchport mode access
- Switch(config-if)#switchport access vlan <no>
- Switch(config-if)#exit
To Verify
- Switch#show vlan brief
Step 3:
Trunk Mode
- Connection between Networking Devices
- Bandwidth Must be in 100Mbps
- It carry two or more Vlan information
- Two Types of trunk modes 802.1q and ISL
Networking Device --> Router to Switch & Switch to Switch
Syntax to create Trunk Mode
- Switch>enable
- Switch#config t
- Switch(config)#interface fastEthernet <portno>
- Switch(config-if)#switchport mode trunk
- Switch(config-if)#switchport trunk allowed vlan all
- Switch(config-if)#exit
To Verify Trunk:
- Switch#show interfaces trunk

Creating Lan
For Creating Lan we need a Switch and PC
PC1 --- ip 192.168.10.1 255.255.255.0
Pc2 --- ip 192.168.10.2 255.255.255.0
Pc3 --- ip 192.168.10.3 255.255.255.0
Pc4 --- ip 192.168.10.4 255.255.255.0
Switch --- Cisco Catalyst 2950
cables used Twisted Pair Straight-trough to connect between Switch to PC
then we try to ping between the pc means it will success....

Accessing Ports to VLAN
Switch#config t
Switch(config)#interface fastEthernet 0/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10
Switch(config-if)#interface fastEthernet 0/2
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10
Switch(config-if)#interface fastEthernet 0/3
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 20
Switch(config-if)#interface fastEthernet 0/4
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 20
Switch(config-if)#^Z
Switch#show vlan brief
VLAN Name Status Ports

To verify
ping between Same database Success
ping between different database failed
