Using the LAN Interface 2
Agilent N8211A/N8212A Performance Upconverter Synthetic Instrument Module, 250 kHz to 20 / 40 GHz 47
A firewall is preventing communication between your
PC and your instrument.
Make sure that your firewall settings allow
communication between your PC and other devices.
The instrument is using Auto-IP (That is, the
instrument assigned itself a 169.254.x.x IP address)
and your PC is not using Auto IP (That is, PC does not
have a 169.254.x.x IP address.)
• Disable Auto-IP on the instrument.
• Configure your PC to use Auto-IP.
Error Messages
• If error messages appear, check the command
syntax before continuing with troubleshooting. If
the syntax is correct, resolve the error messages
using your network documentation or by
consulting your network administrator.
• If an unknown host error appears, try using the IP
address instead of the hostname. Also, verify that
the hostname and IP address for the
N8211A/N8212A have been registered by your IT
administrator.
• Check that the hostname and IP address are
correctly entered in the node names database. To
do this, enter the nslookup <hostname>
command from the command prompt.
No Response
• No packets were received. Check that the typed
address or hostname matches the IP address or
hostname assigned to the N8211A/N8212A. Refer
to “How to Set a Static IP Address" on page 41.
• Ping each node along the route between your
workstation and the N8211A/N8212A, starting
with your workstation. If a node does not respond,
contact your IT administrator.
• If the N8211A/N8212A still does not respond to a
ping, you should suspect a hardware problem.
• Check the N8211A/N8212A connector lights
•
Verify the hostname is not being used with DHCP
addressing
Intermittent Response If you received less packets back then you sent, there
may be a problem with the network. In networks with
switches and bridges, the first few pings may be lost
until these devices “learn” the location of hosts. Also,
because the number of packets received depends on
your network traffic and integrity, the number might
be different for your network. Problems of this nature
are best resolved by your IT department.
