Usage Guidelines
Caution When you use the erase command to erase a file system, you cannot recover the files in the file system.
In addition to the command options shown above, options with the prefix slave that are used to identify
nvram: and flash (such as slavenvram: and slavecat4000_flash:) appear in the command help messages
on the dual supervisor engine redundancy switch.
The erase nvram: command replaces the write erase and the erase startup-confg commands. This
command erases both the startup-config and the private-config file.
The erase /all nvram: command erases all files in nvram: in addition to startup-config file and
private-config file.
The erase cat4000_flash: command erases the VLAN database configuration file.
The erase /all non-default command facilitates the work of a manufacturing facility and repair center.
It erases the configuration and states stored in the nonvolatile storage and resets the Catalyst 4500 series
switch to the factory default settings. The default settings include those mentioned in the Cisco IOS
library as well as those set by the erase /all non-default command (vtp mode=transparent, and the
ROMMON variables: ConfigReg=0x2101, PS1= "rommon ! >" and EnableAutoConfig=1).
