Overview of 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 reboots,
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.)

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.
