Network Engineering Lab 2

Network Engineering Experiment 2 Experiment Name: Login switch and VRP (Comware) Use (Preview part) 1. Review the basic principles of the switch, and then briefly answer the following questions: (1) what is the frame forwarding algorithm of a vswitch? (2) How does a vswitch create its MAC address table? 2. Briefly describe how to log on to the vswitch through the Console port. 3. Briefly describe how to log on to the vswitch through Telnet. 4. What is the main role of the distribution frame? 5. What is VRP (Comware )? 6. List common configuration views of VRP (Comware. 7. List Common commands and views of VRP (Comware), and describe their functions. 8. At least three VRP (Comware) command line skills. Experiment 2: How to log on to a vswitch and VRP (Comware) I. Objective To learn how to log on to a vswitch using the Console port and telnet mode, and how to learn about VRP (Comware) basic command usage and command line skills of VRP (Comware. Ii. Experiment Principles and content 1. Basic working principles of vswitches 2. Main methods and commands for logging on to vswitches 3. VRP (Comware) basic principles and common commands 3. experiment environment and device switches, PCs, twisted pair wires 4. Experiment steps (operation methods and questions) 1. log on to the vswitch using the Console port: (10 points) (1) Select a PC and switch on your experimental platform, and connect the comport of the PC to the Console port of the switch on the distribution frame using twisted pair wires. In the lab report, briefly describe how you connect to the distribution frame. (2) log on to the vswitch using the "Super Terminal" under Windows XP on the PC and check whether the switch can be successfully logged on. Please answer in the lab report: What are the configuration parameters in the Super Terminal serial port Properties dialog box? 2. After successfully logging on to the topic, exercise the following VRP (Comware) command in the Super Terminal window: (25 points) [Any view] displaycurrent-configuration [any view] displaysaved-configuration // [any view] display version [any view] displayinterface Ethernet 0/1 must be displayed after the "save" command is executed (Note: for the S3928P switch, the command changes to display interfaceEthernet 1/0/1) [Any view] return [any view] quit <Quidway> save <Quidway> resetsaved-configuration <Quidway> reboot: (1) what are the main functions of each command executed? (2) What is the main information displayed after each command is executed? (Select a text explanation. Each Command should contain no more than three items.) 3. Try other switch commands you can find, such as using the "sysname" command to modify the switch name. (Do not write the lab report) 4. Try the command line technique of VRP (Comware). Please describe at least three command line skills you have tried in the lab report. (10 points) 5. Use Telnet to log on to the vswitch: (25 points) (1) make necessary pre-configuration on the vswitch, such as configuring the IP address and subnet mask of the vswitch, configure the user password of the logon switch and the permission level of the logon user. Please write the configuration commands you run to complete these pre-configuration into the experiment report. (2) Select a pc (as pc a) on your platform and connect its Ethernet interface to any Ethernet port of the above switch. In the lab report, briefly describe how you connect to the distribution frame. (3) configure the IP address and subnet mask of pc a. Be sure to set the IP address of pc a and the IP address of the switch in the same CIDR block. Please write your configuration to the lab report. (4) use the telnet command in the Windows XP command line window to log on to the vswitch and check whether the logon is successful. (Note: The password entered during logon is not displayed.) If logon is successful, try some VRP (Comware) commands without having to write an experiment report. 6. Understand vswitch plug-and-play: (30 points) (1) Select a vswitch on your experimental platform, in the user view, run the "reset saved-configuration" command and the "reboot" command to clear its configuration. (2) use this switch to form a small LAN, test whether or not the four PCs can be pinged. (Note: Disable the firewall on the PC to ensure that the ping is successful.) in the lab report, to enable the four PCs in the figure to communicate with each other, does the vswitch need to be configured without any configuration? Why? Note: (1) Each team member is required to complete the preceding lab questions 1, 2, 3, 4, and 5 independently. (2) When modifying the IP address of a computer, disable the NIC in "network connection" of "Network Neighbor", modify the IP address, and then enable the NIC, to make sure the new IP address takes effect. 5.
