PurposeCommand or Action
Device# erase nvram
For all platforms except the Class
A Flash file system platforms, this
command erases NVRAM. The
startup configuration file cannot
be restored once it has been
deleted. On Class A Flash file
system platforms, when you use
the erase startup-config EXEC
command, the device erases or
deletes the configuration pointed
to by the CONFIG_FILE
environment variable. If this
variable points to NVRAM, the
device erases NVRAM. If the
CONFIG_FILE environment
variable specifies a flash memory
device and configuration filename,
the device deletes the
configuration file. That is, the
device marks the file as “deleted,”
rather than erasing it. This feature
allows you to recover a deleted
file.
