Saving Changes

Selecting APPLY from a console menu makes the configuration effective for the current session only. The configuration data will be lost if the switch is restarted. To make the configuration effective after a switch restart, select Save Changes to enter the configuration into non-volatile (NV-RAM).

The DES-3326 has two levels of memory: normal RAM and non-volatile or NV-RAM. Configuration changes are made effective by highlighting APPLY and pressing Enter. 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.

Figure 6-5. Main Menu

To retain any configuration changes permanently, highlight Save Changes from the Main Menu. The following screen will appear to verify that your new settings have been saved to NV-RAM:

Figure 6-6. Save Changes Confirmation screen

Once the switch configuration settings have been saved to NV-RAM, they become the default settings for the switch. These settings will be used every time the switch is rebooted.
