Introduction
Today, the Internet is an inseparable part of the business of most businesses.

-

Building a standard, stable and secure network is the initial foundation for the steady
development of an enterprise. Here we propose a network solution for businesses
with the assumed name of a Hoplongtech company with the number of employees in
the future not exceeding 260 people. The solution is built on the foundation, Cisco's
reference design documents, Cisco network equipment, and is refined to suit the
financial conditions of Vietnamese businesses.

Current Status

-

New construction completely (or already have a network but not
standardized). The number of employees is less than 260 people.
Only 1 site requires Internet access.

AI.

P6 Test and evaluate the design to meet the requirements and analyze
user feedback.

1. Recommended Network Devices
-

The Catalyst 2960 Access Switches connect to Core Switch using 1 GigEthernet
uplink ports with Etherchannel technology that combines these 2 links running in
parallel to form a 2Gbps Links running to avoid bottlenecks form access Switch to
Core Switch and provide the ability redundancy between these two connections, if

one has problems the data is automatically transferred to the other, the process is
transparent to the end user.

-

Router 2911
Deliver full cost saving like never before and agile networking through the
intelligent integration of market-leading security, unified communications,
wireless, and application services.
This router provides corresponding interfaces to connect to different types of lines
to the internet, for example: ADSL, FTTH, Leaseline…

Install and configure network services and applications on your choice.
Document and analyze test results against expected results. (M3 – P8)

BI.

1. Configuring DHCP server

a. Configure address IP DHCP for LAN1
-

Configure static IP address on the DHCP server
(172.16.1.202/27) IP address: 172.16.1.202
Subnet Mask: 255.255.255.224
Default Gateway: 172.16.1.193
DNS Server: 8.8.8.8

download by :


-

Configure DHCP service
Pool name: LAN120

Default Gateway: 172.16.1.1
DNS Server: 8.8.8.8

Start IP Address: 172.16.1.0
Subnet Mask: 255.255.255.0
Maximum Number of users: 120

Configure ip-helper address in router allows the router to transmit DHCP
discover packets to a DHCP server known by the router (unicast).
Configure in Router 3
Router(config) # int g0/2

Router (config) #ip helper-address 172.16.1.202

To enable static routing we do configure ip route
Router (config-if) #ip route 0.0.0.0 0.0.0.0 172.16.1.226
Configure in Router 4
Router(config-if) #ip route 172.16.1.0 255.255.255.128 172.16.1.255
Now go to every PC and on their IP configuration tabs, enable DHCP. Every
PC should be able to obtain an IP address, default gateway and DNS server
Eg: PC Admin:

Test the configuration by pinging Route3 from DHCP

b. Configure address ip DHCP for

LAN2 - Configure DHCP service
Pool name: LAN2
Default Gateway: 172.16.1.129
DNS Server: 8.8.8.8
Start IP Address: 172.16.1.192
Subnet Mask: 255.255.255.0

#ip route 172.16.1.128 255.255.255.192 172.16.1.255
Now go to every PC and on their IP configuration tabs, enable DHCP. Every
PC should be able to obtain an IP address, default gateway and DNS server
Eg: PC Tech:

Test the configuration by pinging PC Tech from DHCP

D2. Design a maintenance schedule to support the networked system.

1. Regular maintenance

-

Every month, we send technicians to inspect the entire system and handle
problems within the maintenance scope on a certain day.

a. Frequency check: Periodically, once a month, the company sends technicians
to inspect the entire system and troubleshoot problems of the system.

During the inspection we will have a substitute product to ensure the
company's operation during that time.
b. Periodic maintenance items:
-

For the server:
Control access to network or servers
Test and configure network security services
Check, configure, and update to the latest versions of antivirus software…
Store professional data such as accounting, office operations, client's text file
on different storage devices.
Check and optimize the garbage collection and optimize application
software, office software, and protection software on computer systems
Ensuring the operation of Email, File, Document, Internet, Printing
systems regularly, stably and safely for work
Backup the server configuration (to CD, DVD or tape) to ensure that the
server is always operating properly.
Record system monitoring (maintenance book).

-

For network system:

Configure the network to access computers
Review all network cabling systems, ensure cabling is designed and
placed in an environment that meets technical standards.
Draw a layout of the server, client, peripheral devices, and network cables.
Check and test all cables and pushers to ensure satisfactory signal

transmission.
Record system monitoring (maintenance book).

image simulation of the network system

Expected to have 180 PCs, sets up DHCP to dynamically assign addresses to
users. Lan1(120 host): 172.16.1.2->172.16.1.127 in the address range
172.16.1.0/26
Lan2(60 host): 172.16.1.129->172.16.1.190 in the address
range 172.16.1.128/26

-

VI.

DHCP service has assigned dynamic addresses to the machines used
successfully (presented during installation - M3 part)

M4. Recommend potential enhancements for the networked systems.
-

The system can be expanded but the number should not exceed 260 people

-

Support for deploying the system in a server farm model that allows service
servers to be installed on the same server system or on many different servers to
help improve the system's processing power and help home. design better model
implementation.

-

Building confidentiality and security in the system
Defense in depth: The system must be protected in depth, divided into
many layers and separated into many different layers. Each layer and
layer has different security or containment policies implemented
Using many different technologies: Do not rely on only one technology or
technology product to ensure the security of a certain company's network.
Because if the company's products are found vulnerable by hackers, then

similar products of that company in the network will also be
penetrated easily and the stratification and stratification in the
defense policy is meaningless.
