Examples
This example shows how to reset system configuration to factory defaults.
hostname(config)# delete nvram
This command resets the switch with factory defaults. All parameters will revert to their default factory settings. All static system and dynamic addresses will be removed.
Reset system with factory defaults, [y]es or [n]o?
Press Y or N to proceed.
This example shows how to reset the ATM module in slot A to factory defaults.
hostname(config)# delete nvram atm 1
This command resets the module and restores all settings to factory defaults.
The module is deinstalled until it successfully completes its self tests.
Reset module with factory defaults, [Y]es or [N]o?
Press Y or N to proceed.
