If you generate the replacement configuration file externally, it must comply with the format of files
Note
generated by Cisco IOS devices.
Configuring the Configuration Archive
Using the configure replace command with the configuration archive and with the archive config
command is optional but offers significant benefit for configuration rollback scenarios. Before using the
archive config command, you must first configure the configuration archive. Starting in privileged
EXEC mode, follow these steps to configure the configuration archive:
Command
Step 1
configure terminal
Step 2
archive
Step 3
path url
Step 4
maximum number
Step 5
time-period minutes
Step 6
end
Step 7
show running-config
Step 8
copy running-config
startup-config
Cisco Catalyst Blade Switch 3130 and 3032 for Dell Software Configuration Guide
B-22
Appendix B
Make sure that the switch also has sufficient free memory to execute the configuration replacement
or rollback configuration commands.
Certain configuration commands, such as those pertaining to physical components of a networking
device (for example, physical interfaces), cannot be added or removed from the running
configuration.
A configuration replacement operation cannot remove the interface interface-id command line
–
from the running configuration if that interface is physically present on the device.
The interface interface-id command line cannot be added to the running configuration if no
–
such interface is physically present on the device.
When using the configure replace command, you must specify a saved configuration as the
replacement configuration file for the running configuration. The replacement file must be a
complete configuration generated by a Cisco IOS device (for example, a configuration generated by
the copy running-config destination-url command).
Purpose
Enter global configuration mode.
Enter archive configuration mode.
Specify the location and filename prefix for the files in the configuration
archive.
(Optional) Set the maximum number of archive files of the running
configuration to be saved in the configuration archive.
number—Maximum files of the running configuration file in the configuration
archive. Valid values are from 1 to 14. The default is 10.
Note
(Optional) Set the time increment for automatically saving an archive file of
the running configuration in the configuration archive.
minutes—Specify how often, in minutes, to automatically save an archive file
of the running configuration in the configuration archive.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.

configuration command to specify the location and filename prefix for
the files in the configuration archive.
