10-4 Troubleshooting

Troubleshooting a TCP/IP Network Using a Ping Utility

Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet

to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP

network is made very easy by using the ping utility in the built-in Manager interface (Menu 24.4)

or in your PC or workstation.

Testing the LAN Path to Your Router

To verify that the LAN path to your router is set up correctly, from the Windows 95

(or Windows NT

) run menu, type Ping and the IP address of the router. Press the Enter key.

You should see a message like this one:

Pinging <IP address> with 32 bytes of data

If the path is working, you see this message:

Reply from < IP address >: bytes=32 time=NN ms TTL=xxx

If the path is not working, you see this message:

Request timed out

If the path is not functioning correctly, you could have one of the following problems:

• Wrong physical connections

– Make sure the LAN Link LED is on. If the LAN Link LED is off, follow the instructions

in “LAN Link LED” on page 10-2.

– Check that the corresponding Link LEDs are on for your network interface card and for

the hub ports (if any) that are connected to your workstation and router.

• Wrong network conﬁguration

– Verify that the Ethernet card driver software and TCP/IP software are both installed and

conﬁgured on your PC or workstation.

– Verify that the IP address for your router and your workstation are correct and that the

addresses are on the same subnet.
