Statement introduced in Release 8.5 of Junos OS.
Define Routing Engine firewall authentication tracing 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 named trace-file reaches its maximum size, it is renamed to trace-file.0, then trace-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 named trace-file reaches this size, it is renamed trace-file.0. When the trace-file again reaches its maximum size, trace-file.0 is renamed trace-file.1 and trace-file is renamed trace-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: x k to specify KB, x m to specify MB, or x g to 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. The world-readable option enables any user to read the file. To explicitly set the default behavior, use the no-world-readable option.
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 operations
authentication—Trace authentication events
configuration—Trace configuration events
setup—Trace setup of firewall authentication service
Required Privilege Level
trace—To view this statement in the configuration.
trace-control—To add this statement to the configuration.
