Running Traces 633

About Trace Results The trace commands use the underlying logging mechanism to deliver trace messages. Trace messages are generated with the debug severity level. By default, the only log target that receives debug-level messages is the volatile trace buffer. (To see the contents of the trace buffer, see “Displaying Trace Results” on page 633.)

The volatile trace buffer receives messages for all log severities when any trace area is active. However, if no trace area is active, no messages are sent to the trace buffer regardless of their severity. If you do not enable trace commands, the trace buffer is effectively disabled.

Because traces use the logging facility, any other logging target can be used to capture trace messages if its severity is set to debug. However, since tracing can be voluminous, 3Com discourages this in practice. To enable trace output to the console, enter the command set log console severity debug.

If you attempt to send trace output to a Telnet session, be aware that tracing is disabled for areas processing packets that might be associated with the Telnet session.

Displaying Trace To view the output of currently running trace commands, use the Results following command:

display log trace [{+-/}number-of-messages] [facility facility-name] [matching string] [severity severity-level]

For example, the following command displays a trace log of error-level events:

WX1200# display log trace severity error

KERNEL Jan 15 23:08:10 ERROR duplicate IP address 10.7.122.102 sent from link address 00:05:5d:45:ae:cd

To display a specific number of trace log messages, you must enter a plus sign (+), minus sign (-), or slash (/) before the number. These characters filter the messages displayed as follows:

„+number-of-messages — Displays the specified number of log entries, starting with the oldest in the log.

„-number-of-messages — Displays the specified number of entries, starting with the newest in the log.
