Figure 20-5. Ping Test
The
Infinite times
checkbox, in the
Number of Repetitions
field, tells ping to keep sending data packets to the
specified IP address until the program is stopped.
Save Changes
The DGS-3212SR has two levels of memory, normal RAM and non-volatile or NV-RAM. Configuration
changes are made effective 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 on the
Save Configuration
button in the
Save Changes
page, as shown below.
Figure 20-6. Save Changes
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.
Factory Reset
The
Factory Reset
function has several options when resetting the switch. Some of the current configuration
parameters can be retained while resetting all other configuration parameters to their factory defaults.
Note:
Only the
Reset System
option will enter the factory default parameters into the switch’s non-volatile
RAM, and then restart the switch. All other options enter the factory defaults into the current configuration, but
do not save this configuration.
Reset System
will return the switch’s configuration to the state it was when it left
the factory.
