Cisco Packet Tracer VLAN Configuration Example

Packet Tracer VLAN Configuration

As an example, you can see a VLAN topology below. In this topology, 2 Cisco Catalyst 2950-24 switches and 6 PCs are used.

PC Configurations

For our VLAN Configuration example, we will set our PC IPaddresses as below. These ip addresses will be required at the end of this configuration example to test our configuration.

PC 1 –> 192.168.1.2 VLAN 2
PC 2 –> 192.168.1.3 VLAN 2
PC 3 –> 192.168.1.4 VLAN 3
PC 4 –> 192.168.1.6 VLAN 3
PC 5 –> 192.168.1.7 VLAN 3
PC 6 –> 192.168.1.8 VLAN 2

VLAN Configuration on Switch 1

After PC IP configurations, now, we can start our VLAN Packet Tracer Configuration steps. Here, we will follow the below steps:

 

1. We will set access ports that will access specific VLANs. We will do this with “switchport mode access” command under these interfaces.
2. We will also set the VLAN, that this port will access.
3. After that, we will set the trunk port that will carry multiple VLANs with “swithcport mode trunk” command.
4. Then we will also set this port with “no negotiate” command to prevent negotiation about the port role.
5. Laslty, we will set the allowed VLANs with “switchport trunk allowed vlan” command on this trunk and save our configuration.

 

Switch 1(config)# interface fastEthernet 0/2
Switch 1(config-if)# switchport mode access
Switch 1(config-if)# switchport access vlan 2

Switch 1(config)# interface fastEthernet 0/3
Switch 1(config-if)# switchport mode access
Switch 1(config-if)# switchport access vlan 2

Switch 1(config)# interface fastEthernet 0/4
Switch 1(config-if)# switchport mode access
Switch 1(config-if)# switchport access vlan 3

Switch 1(config)# interface fastEthernet 0/1
Switch 1(config-if)# switchport mode trunk
Switch 1(config-if)# switchport nonegotiate

Switch 1(config-if)# switchport trunk allowed vlan 2-4

Switch 1# copy running-config startup-config

VLAN Configuration on Switch 2

After configuring the first switch, we will configure switch 2 similar to switch 1 as below.

Switch 2(config)# interface fastEthernet 0/2
Switch 2(config-if)# switchport mode access
Switch 2(config-if)# switchport access vlan 3

Switch 2(config)# interface fastEthernet 0/3
Switch 2(config-if)# switchport mode access
Switch 2(config-if)# switchport access vlan 2

Switch 2(config)# interface fastEthernet 0/4
Switch 2(config-if)# switchport mode access
Switch 2(config-if)# switchport access vlan 2

Switch 2(config)# interface fastEthernet 0/1
Switch 2(config-if)# switchport mode trunk

Switch 2(config-if)# switchport nonegotiate

Switch 2(config-if)# switchport trunk allowed vlan 2-4

Switch 2# copy running-config startup-config

Checking VLAN Configuration

Our last step of VLAN Packet Tracer Example is configuration verification. to verify our VLAN Packet Tracer Configuration, we will use verification commands like “show vlan brief“, “show interfaces“, “show interfaces trunk” etc.

Switch# show vlan brief
