I have had many opportunities that I believe will continue to grow and influence my professional life while furthering my personal growth and development in the future. This report would not have been possible without the collaboration and contributions of others. My sincere gratitude goes to these people. The people who helped me during the internship are Mr. Lawrence Chia, the Director of ESBU for approving my application for the internship. Mr. Victor Lim, he is the head of the routing and switching team that I was a part of. Mr. Yusni Yusof, he has been there since I set foot in this company. He is one of the network engineers and he literally taught me the basics of networks from scratch. I am forever grateful for his advice. Last but not least, Ms. Jing Ping, the pre-sales engineer, went the extra mile to help me whenever I encountered difficulties. Say no to plagiarism.

IIntroductionInternship is a fundamental platform for anyone to gain experience in a real workplace. So, NEC Pacific Asia is a good opportunity for students to learn and understand how the IT industry works. This company is primarily project-based, so future interns are expected to meet deadlines, face the inevitable problems that may arise during projects, and be able to make informed decisions that will benefit the company ultimately. long term. Compared to theoretical learning in school, we only scratch the surface, but by doing this internship, I learned the practical approach to dealing with a real world. Most importantly, I believe this internship helped me control my attitude and behavior towards all kinds of people and situations. It made me realize that I was still lacking as an individual and employee who fully helped me identify my strengths and weaknesses. Apart from that, I sincerely wanted to acquire professional knowledge and skills by doing this internship. I wanted to actively contribute to the company's goals by applying what I learned at Republic Polytechnic so that I could seize this golden opportunity to improve current systems or automate theirworkflow. I am confident that everything I have experienced in NEC Pacific Asia will be beneficial in the future. General Organization Information Kunihiko Iwadare founded Nippon Electric Company, Limited in 1899 and was renamed NEC Corporation in 1983, all two expressed today as the NEC. This is Japan's first joint venture with foreign capital in association with the American company Western Electric Company (currently Alcaltel-Lucent). Their motto “Better Products, Better Services” has driven them to provide value to their customers by maintaining high ethical standards, creating world-class products and reliable aftercare service. Fast forward to now, they specialize in providing information and communication technology solutions. The company provides systems integration, managed services and network technology services. NEC solutions are designed to provide customers with exceptional levels of versatility and scalability, giving them the edge in the IT industry. Training and Work Assignments I report to the Enterprise Business Solutions (ESBU) department, but I work specifically with the Routing and Switching team. I am deployed offsite to establish network infrastructure for IMDA. The work processes in which I have been involved start during the deployment phase of this project. The first training we received was wireless deployment. This involves setting coverage and capacity targets that meet the needs of the customer's business objectives. This means introducing a predictive site survey, performing a manual site survey and deployment plans. The tools that will be used in the NEC context would be the Aerohive Wi-Fi scheduling tool in HiveManager Classic. We will need to determine the number of clients expected to serve, the type of traffic expected on the network, the throughput provided by the network, the number of access points (APs) needed and where to mount them for maximum coverage. As such, a predictive model is created before performing a manual site survey to verify the accuracy of the predictions. Subsequently, we can make possible adjustments if necessary. As with the first project, I have to go to the NEC warehouse store to take inventory of the switches that will be placed on levels 3, 4, 5 and 6 of the wiring centers. This simply means that I have to cross-reference the list of materials given to me and transfer it to an Excel sheet in ascending order before the floors. I discovered a free and open source terminal emulator, serial console and network file transfer called PuTTY which involves OSI Layer 2 programming. I need to connect my laptop to the switches in order to do the inventory. Next, I need to identify the serial number and model type of the switch for Excel. So instead of manually looking at the serial number. From each switch, I can simply type a command that lists all the information needed for an inventory check. Next, we will need to put all the switches back in their respective boxes and clean the place, which can be done by 2 people. Once this is done we are ready for deployment, we just need to transport the switches to the site so we need transportation and place them at IMDA's cabling center, Mapletree Business City and this process is finished. I have to go offsite to Mapletree Business City to do real work. Apparently some levels are under construction, so I'll have to wear a helmet everywhere I go for safety reasons. My task differs from day to day. I amwalked into a server room with all the switches and wires connecting one end to the other. My task was to go through levels 3, 4, 5 and 6 each comprising 2 wiring rooms with 3 racks of switches and do some PuTTY programming. I had to do some stacking, which means converting the default switch numbering from 1 to 1, 2,3,4,5 in order. Therefore, I need to create a unique IP address for each part and do another inventory. Second, the team will need to inspect the premises. This means the customer will accompany us to the wiring center (server) and individual switch rooms on each floor so we know which switches on our side will be placed in which room. Apparently we need to establish 2 networks A and B respectively and the installation of switches will be done by hired contractors. Editing must always be done first, otherwise you can't start with anything. I will need to complete another inventory checklist for Network A and the power supply as they are already assigned to different rooms while someone else does the configuration and upgrade for Network A. This may be done in one day, but we wasted time because mounting the switches is difficult. the bottleneck. Third, I was able to listen to the instructions clearly so the next day I was in charge of doing network B. I was trained on site and managed to do some stacking, also creating an address IP under VLAN 1 for switches like version upgrade using WinSCP (file transfer) and inventory check. Fourth, once the switches are up and running, we can already mount the access points. The process begins with the transfer of AP boxes to level 7 where the cabling center is located. Then we need to open it and arrange the APs line by line. It will then be connected by the switch using an Ethernet cable. My colleague will then assign this AP to an available spot from level 3 to level 6 in ascending order. Thus, each floor has approximately 22 to 24 APs multiplied by 4 floors, there is a minimum of 88 APs to be installed by the contractor. Once this task is completed, we need to carry out the certification of Alcatel switches, which can be done in the main console of the wiring center and that's it. Next comes the hardening of Alcatel. Alcatel is one of the brands that NEC offers users for the acquisition of switches. I was given a template to document the hardening of switch A to H of network A. In Excel itself, there are various hardening rules such as Authentication, Authorization, and Accounting (AAA) rules, access rules, banner rules, password rules, clock rules, etc. There is a user-provided description, as in the AAA rule, the "configuration class that enforces access controls to devices, provides a mechanism to track configuration changes, and enforce security policy." This should be applied to user login authentication, local console and VTY lines where applicable. It also shows the commands that should appear from the SSH PuTTY program. So I need to see if the code entered into the switch matches the command given by the user. If it doesn't match, I'll have to recode it to satisfy the user's requirements. Once everything looks the same as the template, I need to take a screenshot and paste it into the Excel template. The other task I had to do was user acceptance testing. I was only told to help the engineer turn the main power on and off and.
