Configuration File Management; Overview - HP PROCURVE 6120 Management And Configuration Manual

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.)

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.
Switch Memory and Configuration
Overview
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.
