<CTRL-B>
7 – Skip current configuration file (Y)
0 – Reboot
Switch will boot from default boot option (firmware) but skip the startup config.file.
This will allow administrator user access to the device using “admin” and <blank>.
The following commands are used to return the switch to factory default settings:
reset saved-configuration
This command will remove the user saved configuration file. To see which file will be deleted, enter
display startup
sys
sysname shed
ntp-service unicast-server 129.250.35.250 (This is pool.ntp.org)
interface Vlan-interface1

Different types of saving:
If you execute the save [ safely ] command without specifying any other keyword, the command saves the configuration to the main startup configuration file. If the force keyword is not specified, you will be prompted to enter the filename to save to e.g. the next-startup configuration file. If the force keyword is specified, the command saves the configuration to the next-startup configuration file that has been specified without prompting for a file name.
Use the save command with the ‘safely’ keyword. Safe mode is slower than fast mode, but more secure. In safe mode, the system saves configuration in a temporary file and starts overwriting the target next-startup configuration file after the save operation is complete. If a reboot or power failure occurs during the save operation, the next-startup configuration file is still retained.
Comware3: save safely [Y]
Comware5: save safely main force [Y] = sa sa ma fo
This will save the running config in flash memory to a config file.
startup saved-configuration harald.cfg main
This will cause the switch to boot from the saved config file at a next power cycle.

AUX user interface is used to log in to the Switch through the console port. A fabric can have up to eight AUX user interfaces. VTY user interface is used to Telnet / SSH to the Switch. A Switch can have up to five VTY user interfaces.

reboot
<CTRL-B>
7 – Skip current configuration file (N)
0 – reboot
This will cause the switch to no longer skip the startup config file after the firmware has loaded.
