Learning by Doing: CISCO Certified Network ... - SCN Research

Basic VLAN
Objective:
To learn how to construct and understand how to use basic Virtual LAN’s in a network.
Tools and Materials:
(1) CISCO switch (1900 series)
(2) straight-through cables
(2) Windows PC workstations with Hyperterminal and Ethereal installed
(1) console cable

Background:
Virtual Lan’s (VLAN’s) are used to keep devices from communicating to each other
without the services of a layer 3 device (router). If you were designing a school it would
be nice to use a VLAN for teachers and a VLAN for students. No communication would
be possible without the use of a router. So let’s get to the “learning by doing!”
Step-By-Step Instructions:
1. Set up and cable the lab as shown. The switch requires no ip address, mask or
gateway.
2. Ping from workstation A to B using DOS. It should work just fine.
3. Now let’s put the teachers on one VLAN and the students on another. From
the switch console let’s create the two VLANs:
a. Click on [M] for menus
b. Click on [V] for VLANs
c. Click on [A] for add a VLAN (this will become VLAN #2)
d. Click on [1] for “Ethernet” type VLAN
e. Click on [S] to save and exit
f. Click on [V] for VLANs
g. Click on [A] for add a VLAN (this will become VLAN #3)
h. Click on [1] for “Ethernet” type VLAN
i. Click on [S] to save and exit
