Switch Memory and Configuration
Multiple Configuration Files
This command makes a local copy of an existing startup-
config file by copying the contents of an existing startup-
config file in one memory slot to a new startup-config file in
another, empty memory slot. This enables you to use a sepa-
rate configuration file to experiment with configuration
changes, while preserving the source file unchanged. It also
simplifies a transition from one software version to another
by enabling you to preserve the startup-config file for the
earlier software version while creating a separate startup-
config file for the later software version. With two such
versions in place, you can easily reboot the switch with the
correct startup-config file for either software version.
• If the destination startup-config file already exists, it is
overwritten by the content of the source startup-config file.
• If the destination startup-config file does not already exist,
it will be created in the first empty configuration memory
slot on the switch.
• If the destination startup-config file does not already exist,
but there are no empty configuration memory slots on the
switch, then a new startup-config file is not created and
instead, the CLI displays the following error message:
Unable to copy configuration to “< target-filename >”.
The oobm parameter specifies that the copy operation will go
out from the out-of-band management interface. If this
parameter is not specified, the copy operation goes out from
the data interface. Refer to Appendix G, “Network Out-of-
Band Management” in this guide for more information on
out-of-band management.
For example, suppose both primary and secondary flash memory contain
software release “A” and use a startup-config file named config1:
