Lab 20 Test vlan

Objective

To understand VLAN.

Topology

Basic Setting

• PC0 is connected to Fa0/1
• PC1 is connected to Fa0/2.
• IPs have been set up.

Requirements

• Create VLAN2.
• Assign Fa0/2 to VLAN2.

Steps

On PC1

PC>ping 192.168.0.2
Pinging 192.168.0.2 with 32 bytes of data:

Ping statistics for 192.168.0.2:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 7ms, Maximum = 9ms, Average = 8ms

All ports on the switch are in the VLAN1,So all the ports can communicated as long as they have IPs in the same segment.

All ports are in the default VLAN.

Create VLAN2

Switch#confi t
Switch(config)#vlan
Switch(config)#vlan 2
Switch(config-vlan)#
             Note: to delete VLAN Switch(config)#no vlan 2

Assign Fa0/2 – 5 to VLAN2

Switch(config-vlan)#exit
Switch(config)#interface range fastEthernet 0/2 - 5
Switch(config-if-range)#switchport access vlan 2
Switch(config-if-range)#

Show VLAN info
