Troubleshooting the LAN Connection
Troubleshooting the Initial Connection
• Error Messages
If error messages appear, then check the command syntax before
continuing with the troubleshooting. If the syntax is correct, then resolve
the error messages using your network documentation.
If an unknown host error message appears, then check the node names
database (usually /etc/hosts) to see that the hostname and IP address are
correctly entered.
•No response
No packets received indicates no response from a ping.
If there is no response, type in the IP address with the ping command.
Check that the typed address matches the IPaddress assigned in the LAN
Settings menu, then check the other addresses in the menu.
Check that the hostname and IP address are correctly entered in the node
names database on your workstation (usually /etc/hosts).
Ping each node along the route between your workstation and the logic
analyzer, starting with the your workstation. Ping each gateway, then
attempt a ping of the remote file server.
If the logic analyzer still does not respond to ping, then you should suspect
a hardware problem with the logic analyzer. To check the logic analyzer
performance, refer to "Verify the logic analyzer performance" in this
section.
• Intermittent Response
If you received 1 to 8 packets back, there is probably a problem with the
network. Because the number of packets received depends on your
network traffic and integrity, the number might be different for your
network.
Use a LAN analyzer or LAN management software to monitor activity and
determine where bottlenecks or other problems are occurring. The logic
analyzer will still function, but communications over the LAN will be
slower.
