Using the LAN to Control the Analyzer
Pinging the Analyzer from Your Computer or Workstation
Verify the communications link between the computer and the analyzer
remote file server using the ping utility.
From a UNIX workstation, type:
ping hostname 64 10
where 64 is the packet size, and 10 is the number of packets
transmitted.
From a DOS or Windows environment, type:
ping hostname 10
where 10 is the number of echo requests.
Normal Response for UNIX
A normal response to the ping will be a total of 9, 10, or possibly 11
packets received with a minimal average round-trip time. The
minimal average will be different from network to network. LAN
traffic will cause the round-trip time to vary widely.
Because the number of packets received depends on your network
traffic and integrity, the normal number might be different for your
network.
Normal Response for DOS or Windows
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.
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, or by
consulting your network administrator.
If an unknown host error message appears, then check that the host
name and IP address for your analyzer are correctly entered from
the front panel. Press
System, Config I/O.
No Response
No packets received indicates no response from a ping.
If there is no response, try typing in the IP address with the ping
command, instead of using the hostname. Check that the typed
address matches the IP address assigned in the
System, Config I/O
menu, then check the other addresses in the menu.
