Back up switch configuration information using TFTP

Use TFTP to back up switch configuration information before using commands to maintain network equipment and modify the configuration file, you should first back up the configuration information of the device, this is very important because tftp commands are commonly used in conjunction with cisco's backup software cisco TFTP server. Take a layer-3 Switch in h3c as an example: ① After logon via telnet, you can see the user's read and write permissions, generation time, and file name in the path where the flash file is saved by dir. We can see that the user's file name is startup. cfg ② find a host that can be connected to him as a tftp server, open the cisco TFTP server, and then enter tftp-I 192.168.0.8 (assuming the address is a tftp server) put startup. cfg indicates startup. the cfg file is uploaded to the tftp server host at 192.168.0.8. I indicates that the file is sent as a binary code. ④ The tftp server prompts that a message is received successfully. It will create a. cfg file in the root directory of the software. It is the configuration file, which can be opened in notepad. You only need to perform the inverse operation to restore the backup to the vswitch.
