Module 1 Question Number: J1-15, Network Construction and Configuration VLANIF and Telnet of Shijia Information Technology Co., Ltd.
(1) Task description
The business of Shijia Information Technology Co., Ltd. has been developing very rapidly in recent years. The company’s senior management suggested setting up branches in other cities to further expand its business. According to the requirements, Xiao Wang, the network administrator of the information department, is responsible for the branch’s network planning and design.
The branch of Shijia Information Technology Co., Ltd. has more than 400 terminals and is divided into development department, administration department, marketing department and network management department. The head office requires that the business of each department does not affect each other. Each department is in an independent broadcast domain, and the gateway address uses the first address of the subnet.
In addition, hosts on each business network segment on the intranet are required to be able to communicate with each other. The branch network topology is as follows:
Task 1: Network equipment selection and interconnection (9 points)
① Select appropriate network interconnection equipment for networking, and use the simulator eNSP to complete the process according to the actual situation. (3 points)
②Choose appropriate connection cables to connect network devices. (2 minutes)
③Connect the network cable to each network device interface as needed. Note: The G0/0/1 port of LSW1 is connected to the G0/0/1 port of LSW2, and the G0/0/2 port of LSW3 is connected to the G0/0/ of LSW2. 2 ports connected. (4 points)
Task 2: Basic configuration of the switch (13 points)
① Use eNSP to perform basic configuration on LSW1, LSW2, and LSW3. LSW1 is configured with a host name of SWITCH_A, LSW2 is configured with a host name of SWITCH_B, and LSW3 is configured with a host name of SWITCH_C. (6 points)
LSW1
[Huawei]sysname SWITCH_A
LSW2
[Huawei]sysname SWITCH_B
LSW3

Task 3: Divide vlan (38 points)
① Divide vlan on LSW1, create vlan10, vlan11, vlan12, vlan13, vlan10 is named kaifabu, vlan11 is named xingzhengbu, vlan12 is named shichangbu, and vlan13 is named wangguan. (8 points)
[SWITCH_A]vlan batch 10 to 14 Info: This operation may take a few seconds. Please wait for a moment...done.

② Divide vlan on LSW2 and create vlan10 and vlan11. (2 minutes)
[SWITCH_B]vlan batch 10 to 13
③ Divide vlan on LSW3 and create vlan12 and vlan13. (2 minutes)
[SWITCH_C]vlan batch 12 13
④ On LSW2, put Ethernet0/0/1 into vlan10 and Ethernet0/0/2 into vlan11. On LSW3, put Ethernet0/0/1 into vlan12 and Ethernet0/0/2 into vlan13. (20 points)
LSW2
