Nonvolatile data is information stored by the Layer 3 Module which is
retained even when the module is not powered on.
You can do the following tasks with nonvolatile data:
Create a backup copy of the module's nonvolatile configuration.
Retrieve the backed-up file.
Reset system data to its factory-configured values, if necessary.
During a save, the contents of nonvolatile memory are written to a disk
file. All configurable parameters are saved in nonvolatile memory,
including:
Module name
Passwords
IP interface configurations
RIP mode setting
SNMP community string settings
SNMP trap destination configurations
The file also contains the following information, which is used to resolve
any inconsistencies when nonvolatile data is restored:
Software version number
System ID
Date and time of creation
Type of configuration
Data checksums
When the module saves nonvolatile data, it writes it to a disk file on a
host computer (that is, a server) using the Trivial File Transfer Protocol
(TFTP). You can then retrieve the information from the disk file by using
the
system nvData restore
command.
