Hierarchy Level

Release Information

Statement introduced before JUNOS Release 7.4.

Description

Specify router advertisement protocol-level tracing options.

Default

The default 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 router advertisement tracing output in the file /var/log/router-advertisement-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: 10 files

flag flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements.

  • all—All tracing operations
  • general—A combination of the normal and route trace operations
  • normal—All normal operations.
Default: If you do not specify this option, only unusual or abnormal operations are traced.
  • policy—Policy operations and actions
  • route—Routing table changes
  • state—State transitions
  • task—Interface transactions and processing
  • timer—Timer usage

no-world-readable—(Optional) Prevent any user from reading the log file.

size size—(Optional) Maximum size of each trace file, in kilobytes (KB) or megabytes (MB). 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: 128 KB

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

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.
