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

4. Now we need to assign ports to the VLAN’s:
a. Click on [E] for VLAN membership
b. Click on [V] for VLAN assignment
c. **Type in the ports to assign for the VLAN: 4-12 (I have a 24-port switch)
d. Click on [2] to assign them to VLAN #2
e. Click on [E] for VLAN membership
f. Click on [V] for VLAN assignment
g. **Type in the ports to assign for the VLAN: 13-24 (I have a 24-port
switch)
h. Click on [3] to assign them to VLAN #3
i. All done! You can exit back to the main menu.
** We typically do not want to use VLAN #1…we reserve it for network
management functions…I saved 3 ports on my 24 port switch for VLAN
#1…If you take the semester 7 “Building CISCO Switched Multi-Layered
Networks” then you will learn more about using VLAN 1…for now restrict
users to VLAN #2 and above.
5. Try pinging again from workstation A to B using DOS. It should not work
now. The VLAN’s “electrically separate” the two networks…it’s kind of like
using two switches.
Supplemental Lab or Challenge Activity:
1. Add a protocol inspector and observe the VLAN information.
2. Go to CISCO’s website and research VLAN information.
3. Try setting up a switch with 5 VLAN’s.
So What Have I Learned Here?
VLANs are nice to use in large networks. Instead of physically separating network users
from each other with separate (and sometimes expensive devices) we can now do it
logically without using added equipment. In the next lab we will add a router into our
little lab design and see how it improves or messes up our network
