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 6-15. 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 6-6-15,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 6-32.)
