Pinging to Test LAN Connectivity

The security appliance and most TCP/IP terminal devices contain a ping utility that sends an ICMP echo-request packet to the designated device. The device responds with an echo reply. Troubleshooting a TCP/IP network is made very easy by using the ping utility in your PC or workstation.

This section includes the following topics:

•Testing the LAN Path from Your PC to Your Security Appliance, page 457

•Testing the LAN Path from Your PC to a Remote Device, page 458

Testing the LAN Path from Your PC to Your Security

Appliance

STEP 1 On your PC, click the Windows Start button, and then click Run.

STEP 2 Type ping <IP_address> where <IP_address> is the IP address of the security appliance. Example: ping 192.168.75.1.

STEP 3 Click OK.

STEP 4 Observe the display:

•If the path is working, you see this message sequence:

Pinging <IP address> with 32 bytes of data

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

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

Pinging <IP address> with 32 bytes of data Request timed out

•If the path is not working, check the physical connections between the PC and the security appliance. If the LAN port light is off, verify that the corresponding link lights are lit for your network interface card and for any hub ports that are connected to your workstation and security appliance.

•If the path is still not up, test the network configuration.

-Verify that the Ethernet card driver software and TCP/IP software are installed and configured on the PC.
