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.

[IP
address]

• 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.
