Checking Current Configuration; Using "Ping" To Test Physical Connectivity - Panasonic DP-1820P Service Manual

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
The following example shows the output after you type "ipconfig /all" at a command prompt:
C:\>ipconfig /all
Windows NT IP Configuration
Host Name
DNS Servers
Node Type
NetBIOS Scope ID
IP Routing Enabled.
WINS Proxy Enabled
NetBIOS Resolution Uses DNS
Ethernet adapter IBMFE1
Description

DHCP Enabled
IP Address
Subnet Mask
Default Gateway
Primary WINS Server
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.
