Saving Configurations While Using the CLI

Saving Configurations While Using the CLI

The switch operates with two configuration files:

Running-Config File: Exists in volatile memory and controls switch operation. Rebooting the switch erases the current running-config file and replaces it with an exact copy of the current startup-config file. To save a configuration change, you must save the running configuration to the startup-config file.

Startup-Config File: Exists in flash (non-volatile) memory and preserves the most recently-saved configuration as the “permanent” configuration. When the switch reboots for any reason, an exact copy of the current startup-config file becomes the new running-config file in volatile memory.

When you use the CLI to make a configuration change, the switch places the change in the running-config file. If you want to preserve the change across reboots, you must save the change to the startup-config file. Otherwise, the next time the switch reboots, the change will be lost. There are two ways to save configuration changes while using the CLI:

Execute write memory from the Manager, Global, or Context configuration level.

When exiting from the CLI to the Main Menu, press [y] (for Yes) when you see the “save configuration” prompt:

Do you want to save current configuration [y/n]?
