2-10 Communications Test
If the basic settings (in particular the IP address and subnet mask) have been
made correctly for the Ethernet Unit, then it should be possible to communi-
cate with nodes on the Ethernet.
This section describes how to use the PING command to perform communi-
cations testing between Ethernet Units.
2-10-1 PING Command
The PING command sends an echo request packet to a remote node and
receives an echo response packet to confirm that the remote node is commu-
nicating correctly. The PING command uses the ICMP echo request and
responses. The echo response packet is automatically returned by the ICMP.
The PING command is normally used to check the connections of remote
nodes when configuring a network. The Ethernet Unit supports both the ICMP
echo request and reply functions.
