Module 1 Question Number: J1-8, Network Construction and Configuration of Xingrui Network Technology Co., Ltd.
(1)Task description
Xingrui Network Technology Co., Ltd. is an entrepreneurial technology company. Due to the recent rapid development of Internet technology, Xingrui Company has also developed rapidly. The number of employees in the company has increased sharply, and the original network can no longer meet the needs of the growing business. The company’s senior management asked Xiaohua, the network administrator of the network department, to re-plan and manage the company’s network in a unified manner to improve network performance and enhance security.
After careful investigation and analysis, Xiaohua decided to expand the existing network of Xingrui Company and re-plan the topology. The topology adopts a relatively common three-layer architecture (access layer, aggregation layer, core layer). In order to ensure that the network can operate safely, normally and stably, the topology of Xingrui Company is as shown in the figure below:
The company network IP addresses are assigned as follows:
Task 1: Network equipment selection and interconnection (9 points)
① Select appropriate network interconnection equipment for networking and use eNSP to complete. (2 minutes)
②Choose appropriate connection cables to connect network devices. (2 minutes)
③Connect the network cable to each network device interface as needed. Note: The GE0/0/1 port of LSW1 is connected to the GE0/0/1 port of LSW2, and the GE0/0/2 port of LSW1 is connected to the GE0/0/2 port of LSW2. 2 ports are connected, the E0/0/5 port of LSW2 is connected to PC1, the GE0/0/6 port of LSW1 is connected to PC2, and the GE0/0/11 port of LSW1 is connected to PC3. (5 points)
Task 2: Basic switch configuration (9 points)
①Use eNSP to perform basic configuration on LSW1 and LSW2. LSW1 is configured with a host name of S_A, and LSW2 is configured with a host name of S_B. (6 points)
LSW1
[Huawei]sysname S_A
LSW2
[Huawei]sysname S_B
② Configure the login password for the CONSOLE port on LSW1 to be console. (3 points)
[S_A]user-interface console 0 [S_A-ui-console0]authentication-mode password [S_A-ui-console0]set authentication password cipher console [S_A-ui-console0]quit
Task 3: Divide vlan (35 points)
① Divide vlan on LSW1 and create vlan10 and vlan30. Divide vlans on LSW2 and create vlan10 and vlan30. On LSW1, GE0/0/6-10 is assigned to vlan10. Assign GE0/0/11-15 to vlan30 on LSW1, and assign E0/0/1-5 to vlan10 on LSW2. (23 points)
