Trace files are effective in helping our Technical Support team pinpoint your problem. The appliance provides a certain amount of tracing continuously. The results can be packaged into an ZIP archive if you click Stop Trace. This archive can be downloaded onto your computer, via Retrieve File. Once downloaded, it can be forwarded to Support. Because the trace files are generated continuously, they also provide crash analysis data.
This tab has a large number of tracing parameters, none of which should be touched except at the request of Support.
The fail-to-wire (Ethernet bypass) functionality of the Ethernet interface can be tested for a user-selected period with the feature. Enter the number of seconds for the unit to fail-to-wire (bypassing all appliance functionality and causing the unit to act as if it had a cross-over cable between the two ports) and click Submit Query. The bypass relay will close for the specified number of seconds. Afterwards, normal operation will resume.
If the appliance software has exited abnormally, core files will have been left behind. The unit will restart automatically after an abnormal exit, except in cases of persistent crashes, where it will disable acceleration while leaving the management interface active.
The “Line Test: SERVER” function starts an iperf server on the appliance, running in TCP mode. Iperf is a free TCP/UDP performance testing tool, available for Windows and UNIX systems from:
The documentation for iperf is also on this site. Iperf is preinstalled on appliances as a convenience.
To run iperf tests, one system (an appliance or other host) must run iperf as a server, and another must connect to it as a client. The defaults on the Diagnostics Tools page are the usual defaults for iperf. Click Start Server to start an iperf server on the appliance.
The “Line Test: CLIENT” function starts an iperf client on the unit, running in TCP mode. You specify the iperf server to connect to, the port number, the interface, and the length of the test. For the latter two parameters, the defaults are usually adequate. When the test is complete, the connection speed will be reported.
The Ping and Traceroute tabs (not shown) allow you to use the standard ping and traceroute utilities to test connectivity to remote systems.
The System Info tab takes you to a page that lists all parameters that are not set to their defaults. This information is read-only. It is used by Support when some kind of misconfiguration is suspected. When you report a problem, you may be asked to check one or more values on this page.
The information is intended for use by Support, and is not documented.
The Diagnostic Data tab packages data for analysis by Citrix Support. There are two features: tracing and one-button data collection. Use them only at the request of Citrix Support, which will provide you with instructions for which options to set and where to send the resulting data files.
