Release Information

Statement modified in Release 9.6 of Junos OS.

Description

Configure NAT tracing options.

Options

filename —By default, the name of the log file that records trace output is the name of the process being traced. Use this option to specify another name.

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.

size maximum-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—Trace operation to perform. To specify more than one trace operation, include multiple flag statements.

all—Trace with all flags enabled
destination-nat-pfe—Trace destination NAT events on PFE-ukernel side
destination-nat-re—Trace destination NAT events on Routing Engine (RE) side
destination-nat-rt—Trace destination NAT events on Packet Forwarding Engine real-time (PFE-RT) side
source-nat-pfe—Trace source NAT events on PFE-ukernel side
source-nat-re—Trace source NAT events on RE side
source-nat-rt—Trace source NAT events on PFE-RT side
static-nat-pfe—Trace static NAT events on PFE-ukernel side
static-nat-re—Trace static NAT events on RE side
static-nat-rt—Trace static NAT events on PFE-RT side

no-remote-trace—Set remote tracing as disabled.
