Release Information

Statement introduced before JUNOS Release 7.4.

Support for routing instances introduced in JUNOS Release 9.0.

Description

Set RIPng protocol-level tracing options.

Default

The default RIPng protocol-level trace options are inherited from the global traceoptions statement.

Options

disable—(Optional) Disable the tracing operation. One use of this option is to disable a single operation when you have defined a broad group of tracing operations, such as all.

file filename—Name of the file to receive the output of the tracing operation. Enclose the name in quotation marks. We recommend that you place RIPng tracing output in the file /var/log/ripng-log.

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 must also specify a maximum file size with the size option.

Range: 2 through 1000 files
Default: 1 trace file only

flag flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. The following are the RIPng–specific tracing options:

The following are the global tracing options:

Default: If you do not specify this option, only unusual or abnormal operations are traced.

flag-modifier—(Optional) Modifier for the tracing flag. You can specify one or more of these modifiers:

no-world-readable—(Optional) Disallow any user to read the log file.

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 must also specify a maximum number of trace files with the files option.

Syntax: xk to specify KB, xm to specify MB, or xg to specify GB
Range: 10 KB through the maximum file size supported on your system
Default: 1 MB

world-readable—(Optional) Allow any user to read the log file.
