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 tracing operations for the PPP process.
To specify more than one tracing operation, include multiple flag statements.
You cannot specify a separate trace tile. Tracing information
is placed in the system syslog file in the directory /var/log/pppd.
Default
If you do not include this statement, no PPPD-specific tracing operations are performed.
Options
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. By default, commit script process tracing output
is placed in the file ppd. If you include the file statement, you must specify a filename. To retain the default, you
can specify eventd as the filename.
files number—(Optional)
Maximum number of trace files. When a trace file named trace-file reaches its maximum size, it is renamed trace-file.0, then trace-file.1, and so on, until the maximum number of trace files is reached.
Then the oldest trace 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
Default: 3 files
disable—(Optional) Disable the tracing operation.
You can use this option to disable a single operation when you have
defined a broad group of tracing operations, such as all.
flag—Tracing operation
to perform. To specify more than one tracing operation, include multiple flag statements. The following are the PPPD-specific tracing
options.
access—Access codeaddress-pool—Address pool codeall—All areas of codeauth—Authentication codechap—Challenge Handshake Authentication Protocol (CHAP) codeconfig—Configuration codeifdb—Interface database codelcp—LCP state machine codememory—Memory management codemessage—Message processing codemlppp—Trace MLPPP codencp—NCP state machine codepap—Password Authentication Protocol (PAP) codeppp—PPP protocol processing coderadius—RADIUS processing codertsock—Routing socket codesession—Session management codesignal—Signal handling codetimer—Timer codeui—User interface code
match regex—(Optional)
Refine the output to include only those lines that match the given
regular expression.
size 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:
xkto specify KB,xmto specify MB, orxgto specify GB
Range: 10 KB through 1 GB
Default: 128 KB
world-readable—(Optional) Enable unrestricted
file access.
non-world-readable—(Optional) By default, log
files can be accessed only by the user who configures the tracing
operation. Specify non-world-readable to reset the default.
Required Privilege Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
