1 Verify the communications link.
Verify the communications link between the PC and the logic analyzer using
the ping utility or other similar echo request utility.
To aid in troubleshooting, go to the Ethernet Statistics menu under LAN
Settings on the logic analyzer. You can view transmit and receive activity on
this menu. If needed, refer to "Network Status Information" in this chapter
for more information about the Ethernet Statistics menu.
If the ping utility is not available on the PC, then this is an indication that the
PC-based NFS software is not properly installed. Reinstall the PC-based NFS
software and attempt to verify the communications link.
The syntax of the ping command varies with the NFS software used. Usually,
the command requires at least the IP address.
If
the syntax permits a
specified number of echo requests, then specify 10 as the number of echo
requests. Refer to the NFS software documentation for more information.
ping
[IP
address] 10
• Normal Response
A normal response to the ping will be a total of 9, 10, or possibly 11
packets received if 10 echo requests were specified. Because the
number of packets received depends on your network traffic and
integrity, the normal number might be different for your network.
For every packet transmitted and received because of the ping
command, the Transmit Successful and Receive Successful fields in
the Ethernet Statistics menu increases by 1.
Go to step 2, "Attempt a remote NFS mount."
• 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 NFS documentation.
Certain PC-based NFS software packages permit the use of hostname
in place of the IP address. In this case, if an unknown host error
message appears, then check the node names database to see that the
hostname and IP address are correctly entered.
Refer to the NFS software documentation for specific information on
any error messages.
