DES-3526 / DES-3526DC Fast Ethernet Layer 2 Switch
Ping Test
Ping is a small program that sends ICMP Echo packets to the IP address you specify. The destination
node then responds to or "echoes" the packets sent from the Switch. This is very useful to verify
connectivity between the Switch and other nodes on the network.
Figure 9- 7. Ping Test window
The user may use Infinite times radio button, in the Repeat Pinging for field, which will tell the ping
program to keep sending ICMP Echo packets to the specified IP address until the program is stopped.
The user may opt to choose a specific number of times to ping the Target IP Address by clicking its
radio button and entering a number between 1 and 255. Click Start to initiate the Ping program.
Save Changes
The DES-3526 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 window will appear:

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:
