Saving Changes

The DES-3550 has two levels of memory, normal RAM and non-volatile or NV-RAM.
Configuration changes are made effective by clicking the Apply button. When this is done, the
settings will be immediately applied to the switching software in RAM and will immediately
take effect.
Some settings, though, require you to restart the Switch before they will take effect. Restarting
the Switch erases all settings in RAM and reloads the stored settings from the NV-RAM.
Thus, it is necessary to save all setting changes to NV-RAM before rebooting the Switch.
To retain any configuration changes permanently, click the Save Changes link in the
Maintenance folder. The following screen will appear:
Figure 9- 7. Save Changes Screen
Click the Save Configuration button to save the current switch configuration in NV-RAM.
The following dialog box will confirm that the configuration has been saved:
