Switch Memory and Configuration

Overview

Overview

This chapter describes:

How switch memory manages configuration changes

How the CLI implements configuration changes

How the menu interface and web browser interface implement configu­
ration changes

How the switch provides software options through primary/secondary
flash images

How to use the switch’s primary and secondary flash options, including
displaying flash information, booting or restarting the switch, and other
topics

Configuration File Management

The switch maintains two configuration files, the running-config file and the
startup-config

file.

Volatile Memory

Running-Config File

(Controls switch operation. When the switch boots, the
contents of this file are erased and replaced by the
contents of the startup-config file.)

Flash (Non-Volatile) Memory

Startup-Config File

(Preserves the most recently saved configuration
through any subsequent reboot.)

CLI configuration
changes are written to
this file. To use the CLI to
save the latest version of
this file to the startup­
config file, you must
execute the write
memory
command.

Menu interface configu­
ration changes are simul­
taneously written to both
of these files.

Conceptual Illustration of Switch Memory Operation

Running Config File:

Exists in volatile memory and controls switch

operation. If no configuration changes have been made in the CLI since
the switch was last booted, the running-config file is identical to the
startup-config file.
