Saving Configuration Changes
The show command always displays the running configuration of the switch.
When you make a configuration change to a switch or switch cluster, the change
becomes part of the running configuration. The change does not automatically
become part of the config.txt file in Flash memory, which is the startup
configuration used each time the switch restarts. If you do not save your changes
to Flash memory, they are lost when the switch restarts.
To save all configuration changes to Flash memory, you must enter the write
memory command in privileged EXEC mode.
Note The write memory command does not apply to the Catalyst 1900 and
Catalyst 2820 switches, which automatically save configuration changes to
Flash memory as they occur.
Tips As you make cluster configuration changes, make sure you periodically save
the configuration. The configuration is saved on the command and member
switches.

procedures are provided.
