Switch Memory and Configuration

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.

Figure 6-1. 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.

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.)

Startup-Config File

(Preserves the most recently saved configuration

through any subsequent reboot.)

Volatile Memory

Flash (Non-Volatile) Memory

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.
