How does a layer-3 Switch clear configuration files?

We all know how to clear the configuration file of the ZTE layer-3 switch. The cisco switch clearing configuration is erase startconfig! Then reload. However, ZXR10 series switches do not have this command. ZXR10 saves the configuration as write, and writes the configuration information to flash. There is a cfg folder under flash, the file is saved in the configuration file written in. You only need to delete the file and restart the switch. The specific command for www.2cto.com is: ZXR10 # cd cfg // switch to the folder ZXR10 # DIR // view the file Directory of flash:/cfgZXR10 # delete startrun. cfgAre you sure to delete files?
