Trace dumps

How a trace dump is used
The generation of a trace dump causes a CRITICAL message to be logged to the system error log.
When a trace dump is detected, issue the supportSave command on the affected switch. This
command packages all error logs, the supportShow output, and trace dump, and moves these to
your FTP server. You can also configure your switch to automatically copy trace dumps to your FTP
server (refer to “Setting up automatic trace dump transfers”).
In addition to automatic generation of trace dumps on faults, you can also generate a trace dump
manually or when certain system error messages are logged. This is normally done with assistance
from Brocade customer support when diagnosing switch behavior.
For details on the commands, refer to the Fabric OS Command Reference.
Setting up automatic trace dump transfers
You can set up a switch so that diagnostic information is transferred automatically to a remote
server. Then, if a problem occurs you can provide your customer support representative with the
most detailed information possible. To ensure the best service, you should set up for automatic
transfer as part of standard switch configuration, before a problem occurs.
Setting up for automatic transfer of diagnostic files involves the following tasks:
• Specifying a remote server to store the files.
• Enabling the automatic transfer of trace dumps to the server. (Trace dumps overwrite each
other by default; sending them to a server preserves information that would otherwise be lost.)
Specifying a remote server
To specify a remote server, perform the following steps.
1. Open the Switch Administration window.
2. Click Show Advanced Mode, if it is not selected.
3. Select the Trace tab.
4. Enter the FTP host IP address, path of the remote directory for the trace dump files, FTP user
name, and FTP password in the appropriate fields.
The IP address can be IPv4 or IPv6 format, or a DNS name.
The password is optional if you log in as an anonymous user.
5. Click Apply.
Enabling automatic transfer of trace dumps
To enable the automatic transfer of trace dumps, perform the following steps.
1. Open the Switch Administration window.
2. Click Show Advanced Mode, if it is not selected.
3. Select the Trace tab.
4. Select Enable in the Auto FTP Upload section to enable automatic uploading of the trace dump
to the FTP host.
