i'm not able to erase configuration file , i have hp 5920 brand new Switch i was try to make irf, unfortunately i could not make it happen neither i could able to erase configuration file from current config,

reset sa
reset saved-configuration m
reset saved-configuration main
The saved configuration file will be erased. Are you sure? [Y/N]:y
Configuration file in flash: is being cleared.
Please wait ...
MainBoard:
Configuration file is cleared.

display startup
Current startup saved-configuration file: flash:/startup.cfg
Next main startup saved-configuration file: flash:/startup.cfg
Next backup startup saved-configuration file: NULL
delete startup.cfg
Delete flash:/startup.cfg? [Y/N]:y
Deleting file flash:/startup.cfg... Done.
reboot
Start to check configuration with next startup configuration file, please wait.........DONE!
Current configuration may be lost after the reboot, save current configuration? [Y/N]:n
This command will reboot the device. Continue? [Y/N]:y
Now rebooting, please wait...

If you need to reconfigure a Huawei device and do not want to delete its configuration line by line, it is the fastest way to restore the device to the default configuration. Reset saved-configuration command does not delete the existing configuration file in storage device. It is required to restart the device to activate changes. Before reboot, the device compares the configuration file to be loaded at the next startup and existing file to be deleted. Finally the device:

One needs to be familiar with Huawei network devices, such as routers, switches and firewalls, so as to configure them. Huawei has developed a general operating system for these network devices, which undoubtedly reduces the learning cost for IT practitioners. Versatile Routing Platform (VRP) is a general network operating system for Huawei network devices.

When configuring Huawei network devices for the first time, you usually log in through the Console port. After the network is configured, you can log in to the network devices through Telnet, SSH, or Web to configure the device. The general configuration of the network devices includes changing the device name, setting the device clock, configuring the IP address for the network device interface, and setting the login password.

The configuration of the device will take effect immediately after completion. At this point, the current configuration can be viewed by the display current-configuration command and can be saved by the display saved-configuration command. In addition, the configuration file to be loaded at the next boot can also be changed.

VRP manages all files (including configuration files, system files, License files and patch files of the device) and directories on the device through the file system. The VRP file system is mainly used to create, delete, modify, copy and display files and directories on the device.

VRP can run on a variety of hardware platforms, including routers, LAN switches, ATM switches, dial-up access servers, IP telephony gateways, carrier-grade integrated service access platforms, intelligent service selection gateways and dedicated hardware firewalls. VRP has a consistent network interface, user interface and management interface, providing users with flexible and rich application solutions, as shown in Fig. 3.1.

With TCP/IP protocol stack as the core, VRP implements various data link layer, network layer and application layer protocols, integrates data communication functions such as routing and switching technology, QoS technology, security technology and IP voice technology in the operating system, and provides excellent data forwarding function for network devices based on IP forwarding engine technology.

The commands in the VRP command line consist of keywords and parameters, and the total number of commands mounts to thousands. In order to realize the layered management of these commands, the VRP system registers them under different views according to the types of their functions. VRP command levels are divided into level 0 (visit), level 1 (monitoring), level 2 (configuration) and level 3 (management), while users logging into network devices are divided into levels from 0 to 15. Users of different levels can execute commands of different levels.

The function configuration and service deployment of Huawei network devices are done through VRP command lines. A command line is a string with a certain format and functions registered inside the device. A command line consists of keywords and parameters. Keywords are a set of words or phrases related to the function of the command line. A command line can be uniquely identified by keywords, and keywords of command lines are in bold font in this book. Parameters are words or numbers specified to improve the format of the command line or to indicate the object of the command, including data types such as integers, strings and enumerated values. For example, in the command line ping ip-address for testing inter-device connectivity, ping is the keyword of the command line and ip-address is the parameter (its value is an IP address).

A newly purchased Huawei network device is initially configured to be empty. If you want it to have functions such as file transfer and network interoperability, you need to enter the command line interface of the device and configure it using corresponding commands.

The command line interface is the interface for text-based command interaction between the user and the device, just like the Disk Operation System (DOS) window in the Windows operating system. The VRP command line interface is shown in Fig. 3.2.

The command line interface is divided into several command line views. When using a command line, you need to first enter the view where the command line is located. Commonly used command line views are the user view, system view and interface view, which are inter-related but have certain differences.

From the system view, you can enter the interface view, protocol view, AAA view and other views. To configure parameters such as interface parameters, routing protocol parameters and IP address pool parameters, you have to enter their respective views. By entering different views, you can use the commands in that view. If you want to enter other views, you must first enter the system view.

The VRP system has classified commands and users, with each command having a corresponding level, and each user its own privilege level. The user privilege level corresponds with the command level in a certain way. After logging in, users with certain privilege levels can only execute commands equal to or lower than their own levels.

VRP commands are divided into four levels, i.e., level 0 (visit), level 1 (monitoring), level 2 (configuration) and level 3 (management). Network diagnostic commands belong to the visit level commands, and are used to test whether the network is connected or not. Monitoring level commands are used to view the network status and basic information of the device. Configuration level commands are required for service configuration of the device. For some special functions, such as uploading or downloading configuration files, management level commands are needed.

User privileges are divided into 16 levels from 0 to 15. By default, level 3 users can operate all commands of the VRP system, which means that users of levels 4 to 15 have the same privilege as level 3 users by default. User privileges of levels 4 to 15 are generally used in conjunction with the functions to upgrade command levels. For example, when there are many device administrators, their privilege levels should be further categorized, and then you can elevate the user privilege corresponding to a key command, such as to level 15, so that the default level 3 administrator can no longer use the key command.

Once you enter the user view, you can use commands to understand the basic information of the device and view the device status, etc. If you need to configure interface GigabitEthernet1/0/0, you need to enter the system view first using the system-view command, and then use the interface interface-type interface-number command to enter the corresponding interface view.

The function of the quit command is to exit from any view to the view of the previous level. For example, the interface view is entered from the system view, so the system view is the view of the previous level of interface view.

Some command views are in such a high level that you need to execute the quit command several times in order to exit from the current view to the user view. In this case, you can use the return command to directly exit from the current view to the user view.

The VRP system provides rich command line input methods, supporting multi-line input. The maximum length of each command is 510 characters. The command keywords are not case-sensitive. And incomplete keyword input is supported. Table 3.2 lists the functions of some commonly used function keys in the command line input process.

Online help is a real-time help function provided by the VRP system. When entering command lines, users can enter a question mark (?) at any time to obtain online help. You can choose to obtain full help or partial help.

shortcut keys can further improve the efficiency of command line input. VRP system has defined some shortcut keys, which are called system-defined shortcut keys. System-defined shortcut keys have fixed functions and cannot be redefined by the user. Common VRP system-defined shortcut (combination) keys are shown in Table 3.3.
