Description
Objective:
In this lab we will continue learning about how to configure VLANs in a CISCO environment by building
on the previous assignments. This lab will include the addition of another VLAN and require a unique
address space for each VLAN.
The addition of a router will allow a unique addressing space for each
VLAN. Review the included links and videos to assist in the configuration of the CISCO equipment
needed to complete this complex assignment. This assignment will demonstrate how VLANs are used to
create multiple unique networks on a single piece of networking hardware. This lab will utilize the
Institute of Electrical and Electronics Engineers (IEEE) standard ethernet frame and the IEEE 802.1Q
standard for VLAN tagging.
While building the Packet Tracer model be sure to save the command input/outputs to a .txt file and
create incremental saves of your work. These will help to identify errors, if you have any trouble with
your configuration.
The TA will be available to assist you with this lab.
Supporting Concepts for Lab 5:
*Lab 1 – CISCO Packet Tracer Training
*Lab 2 – Build Cat5e Patch-Cable / T568B Pinout
*Lab 3 – Connecting to Equipment utilizing Console Interface (Putty/xTerm)
*Lab 4 –Static VLAN Configuration | Trunk Interfaces
2 Credit for this assignment will require:
1) Packet Tracer file: CNT4703C-Lab5-[full-name-of-student]
2) Screenshots of Packet Tracer Model
a. Network Topology (Logical)
b. Successful Ping from PC to PC
c. Unsuccessful Ping from PC to PC (between VLANs)
d. Command Output: [hostname]#show vlan
3) Photos of Switch/Router/Workstations
a. Configuration of Interfaces (IPv4)
i. 1 Workstation from each VLAN
b. Command Output:
i. Router: #show ip int brief
ii. Switch: #show vlan
iii. Ping from Router to Workstation
iv. Ping from Workstation to Workstation
LAB 5 Questions:
1) On the CISCO Router/Switch:
a. How many sub-interfaces were used?
b. What is the command to check how the interfaces are configured?
c. What is the command to check what VLANs are set?
d. Which port(s) were trunked?
2) How many Mask Bits are there in a 192.168.100.0/28 subnet?
a. What is the subnet mask? Convert this mask to binary.
b. How many addresses are available in this subnet?
3) What is the maximum length you can run CAT5e?
4) What is a MAC Address?
5) What is a gateway and what purpose does it serve on a network?
