Assignment Background Information
This project will provide support for high-definition IP cameras for DeVry’s campus network.
In Phase 1, you designed a network switching infrastructure that supported both the existing data traffic
as well as additional camera traffic. In Phase 2, you created standards and provided a configuration
template for implementation teams to use in future deployments. In Phase 3, you investigated and
presented recommendations for minimizing Layer 2 loops and VTP. In Phase 4, you will consider
unanticipated extensions to the current network.
Phase 4 Assignment
Your manager recently received a request from the nursing school to integrate its isolated network into
DeVry’s campus network. After a site survey and a number of meetings, specific requirements for the
nursing school were identified.
As the network engineer, your manager has asked you to provide a solution that incorporates these
requirements into DeVry’s current campus network. Additionally, he asks that your solution consider the
university’s current network budget, so cost-effectiveness is a major consideration.
Design Requirements
Your network solution should address the need to integrate the nursing school network into your newly
designed campus network. The nursing school network needs to be redesigned with the following
devices.
I will respond in line. Total cost of everything is about 15k – I realize this is high, but I could not reason to
find a cheaper router with specified needs – a cheaper switch as compared to the rest of the initial
network would not make sense given lower cost routers do not offer the ports, capabilities, and
necessary growth. Note that all of the below has been written after watching the online meeting and
noting that no configurations are required. Thus, only hardware and their purpose, cost, and
performance are measured.
1. One router with three interfaces
a1. To keep costs lower and meet our needs I am choosing a 7204VXR Cisco router because it
has one fixed port switch and it has 4 ports (1 fixed 3 not – interfaces). Also, it is the lowest tier of
router in this class thus the cost is lowest of its series (price could not be found). Lastly the router
offers security and Vlan configurations. 1.8 Gbps with NPE-G2 speeds offer the necessary backbone
speeds to connect to DeVry network, meet camera needs, and offer security. The specs of the router
as provided by cisco can be found at http://www.cisco.com/c/en/us/products/routers/7204vxrrouter/index.html.
The cost of the router is 7,363.00.

2. One fixed port switch
a2. I am choosing a 3750E-48TD switch because it is a fixed port switch and offers 48 ports thus
allowing for growth beyond the 24 estimated needed ports at start. Not only that this switch
offers PoE for the cameras that will be connected. Also, the speeds offered are sufficient for all
data, voice, and camera traffic. Lastly this switch has backwards compatibility with all other
switches and offers port / vlan options & security. Below are raw specs from cicsco.com
Cost: 5,375.00

3. Four subnets and VLANs
For simplicity sake the four subnets are as follows. I chose these arbitrary number schemes
because it does not confuse configuration with my previously configured networks in this
phased design.
1. Camera’s – 10.10.0.0 / 255.255.255.0 – Vlan: Cams
2. Data & voice 1 – 10.11.0.0 / 255.255.255.0 – Vlan: DV1
3. Data & voice 2 – 10.12.0.0 / 255.255.255.0 – Vlan: DV2
4. Data& Voice 3 – 10.13.0.0 / 255.255.255.0 – Vlan: DV3
4. Voice, four video surveillance cameras , and data support
The router and switch chosen both facilitate data, voice, and camera traffic. More specifically
the switch offers POE for the camera’s. Both also router voice and data separately, offering QoS
for voice priority of lan.
5. Twenty-four currents hosts with anticipated growth
Anticipated growth is met with the 48 port switch I chose above since it holds 24 more ports
than is initially required.
6. One local file and DHCP server
Cisco UCS C220 M3 Rack Server will be used with Windors server 2008 r2. The reason for
choosing this server is because it is general purpose suited and thus can be a local file and DHCP

server. It can also support up to 256 virtual configurations. Also, it supports TPM for security
thin the server network. Price: $1,889.99
Deliverables
You are required to prepare a detailed network report for your manager at the next scheduled meeting.
Your report should include the following.
1. Type of networking equipment, switches, router, and so forth
2. Network requirements based on current and future needs
3. A proposal for a cost-effective method to interconnect the nursing school to the DeVry campus
network because it is remote
IMPORTANT: A report template is provided beginning on the next page, and you must use it to submit
your assignment. Before submitting your assignment, delete the first three pages of this document,
containing the instructions.
Your submitted assignment should begin with the title page and only contain your report.
