Switch Memory and Configuration
Multiple Configuration Files
1. Reboot the switch through the Primary boot path using the startup-config
file named backupConfig.
2. Use the CLI to make configuration changes in the running-config file, and
then execute write mem.
The result is that the startup-config file used to reboot the switch is modified
by the actions in step 2.

Figure 6-18. Example of Reboot Process and Making Changes to the Startup-Config
File
Creating an Alternate Startup-Config File. There are two methods for
creating a new configuration file:
■ Copy an existing startup-config file to a new filename, then reboot the
switch, make the desired changes to the running-config file, then execute
write memory. (Refer to figure 6-18, above.)
■ Erase the active startup-config file. This generates a new, default startup-
config file that always results when the switch automatically reboots after
deletion of the currently active startup-config file. (Refer to “Erasing a
Startup-Config File” on page 6-33.)
The commands described later in this section enable you to view the current
multiple configuration status, manage multiple startup-config files, configure
reboot policies, and override reboot policies on a per-instance basis.
