Planning And Designing A Network For MNO Enterprise: Report Requirements

Design Objectives

The network designed we are proposing is purposed to serve MNO business enterprises. The business enterprise has five departments namely admin, sales, engineering finance and human resource department to be served with the proposed network. It should be put into consideration that the network to be design will be constructed on employee instructional reasons but for administrative intentions. That is, the employees of MNO are not the ones to instruct the network construction engineers what they would want the network to do for them [1].

Design Objectives  

The network to be designed has to achieve the following business objectives:

• Scalability: the designed network will be flexible to introduce fresh departments without redesigning the network afresh. Additionally, the designed network will support MNO business enterprises in the next five or so years.
• Security: his network design intends to provide total security to enterprise’s computational environment. This will be achieved by use of access-lists and Sophos firewall device.

Intended network users  

Finance, administration, engineering, human resource and sales departments are the key intended users or the proposed network. Gussets and customers will be partial users of the network since they will obtain information that has been processed by the network. The later users will have no direct access to the network.

Project hardware requirements   

To implement the above mentioned network design, tabulated below are project hardware requirements.

Access point configuration

To configure our access points, follow the steps below:

1. Make sure the access point is powered.
2. Insert network cable to one of the ports on the AP
3. Insert the other end of the cable in your computer.
4. Read behind the AP the default settings. NB. Most of the default settings are 192.168.1.1 as the default gateway and admin admin as the username and passcode respectively.
5. Change the IP address of your computer to statically match that one of AP’s LAN.
6. Access the browser from your laptop
7. Type in the URL the default gateway of the AP
8. Configuration interface will be displayed as below
9. Setting the IP address range

Configure the ip address as below. Make sure your LAN IP address match respectively. Click “Save Changes”. The AP will automatically restart.Configure Wireless access point SSID as shown below.

1. NB, each step all the changes required to be saved at every step. The Wireless AP is ready for use.

DHCP server configuration

Once the server is powered and running, IP should be assigned manually. Follow the images below on how to do it.The DHCP service will be enabled as the figure below. Be keen on the parameters being used 

Security configuration

The security will be implemented by use of access lists. Router will be the tool of implementation. Commands below are employed

HQMainRouter(dhcp-config)#ne

HQMainRouter(dhcp-config)#net

HQMainRouter(dhcp-config)#network ?

a.b.c.d                 Network number in dotted-decimal notation

HQMainRouter(dhcp-config)#network 192.168.50.0 ?
