Description
Enabling tracing can adversely impact scale and performance and may increase security risk. We strongly recommend using the trace, tracing, or traceoptions commands only under the guidance of a JTAC support engineer. After collecting the debug information, immediately disable tracing to minimize risk and restore normal system performance.
Define Routing Engine firewall authentication tracing options.
Options
file filename—Name of the file to receive the output of the tracing operation. Enclose the name within quotation marks. All files are placed in the directory/var/log.files number—(Optional) Maximum number of trace files. When a trace file namedtrace-filereaches its maximum size, it is renamed totrace-file.0, thentrace-file.1, and so on, until the maximum number of trace files is reached. The oldest archived file is overwritten.If you specify a maximum number of files, you also must specify a maximum file size with the size option and a filename.
Range: 2 through 1000 files
Default: 10 files
match regular-expression—(Optional) Refine the output to include lines that contain the regular expression.sizemaximum-file-size—(Optional) Maximum size of each trace file, in kilobytes (KB), megabytes (MB), or gigabytes (GB). When a trace file namedtrace-filereaches this size, it is renamedtrace-file.0. When thetrace-fileagain reaches its maximum size,trace-file.0is renamedtrace-file.1andtrace-fileis renamedtrace-file.0. This renaming scheme continues until the maximum number of trace files is reached. Then the oldest trace file is overwritten.
If you specify a maximum file size, you also must specify a maximum number of trace files with the files option and filename.
Syntax:
xkto specify KB,xmto specify MB, orxgto specify GB
Range: 10 KB through 1 GB
Default: 128 KB
world-readable | no-world-readable—(Optional) By default, log files can be accessed only by the user who configures the tracing operation. Theworld-readableoption enables any user to read the file. To explicitly set the default behavior, use theno-world-readableoption.flag flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. You can include the following flags.
all—All tracing operationsauthentication—Trace authentication eventsconfiguration—Trace configuration eventssetup—Trace setup of firewall authentication service
