11.3 Pinging to Test LAN Connectivity
Most TCP/IP terminal devices and firewalls contain a ping utility that sends an ICMP
echo-request packet to the designated device. The DSR responds with an echo reply.
Troubleshooting a TCP/IP network is made very easy by using the ping utility in your
PC or workstation.
