2. Checking Current Configuration
Print the current unit Internet Parameters configuration.
Locate a PC connected to the same Subnet Mask as the unit, then from the DOS Prompt, type the
following command-line utility: "ipconfig /all" for Windows 98/Me/2000/NT/XP.
Verify that the displayed Network configuration on the PC, matches the following Internet Parameter
settings of the unit:
Default Gateway IP Address:
DNS Server IP Address:
Subnet Mask: (whether it is valid)
For Windows 98 / Me / 2000 / NT / XP / Windows Server 2003
The following example shows the output after you type "ipconfig /all" at a command prompt:
From the above examples, you know the Network configuration for the specified Subnet Mask is as
follows: IP Address: 192.168.3.4; Subnet Mask: 255.255.255.0; Default Gateway (Default Router IP
Address): 192.168.3.254; DNS Server: 192.168.1.1, and the Domain Name: labo.pcc.com
(obtained from the Host Name).
3. Using "PING" to Test Physical Connectivity
The Packet Internet Groper (PING) is a command-line tool included with every Microsoft TCP/IP client
(any DOS, or Windows client with the TCP/IP protocol installed). PING is a simple utility that is used to
send a test packet to a specified IP Address, or Hostname, then, if everything is working properly, the
packet is echoed back (returned).
Sample command-line PINGing, and parameters are shown below. There are several available
options that can be specified with the PING command. However, for our examples, we will use two
options (-n, and -w) which are commonly used when the response from the destination location is too
long.
-n count : The number of echo requests that the command should send. The default is four.
-w timeout : Specifies the period PING will wait for the reply before deciding that the host is not
responding.
