Release Information

Statement introduced in JUNOS Release 9.4.


Define tracing operations for ANCP processes.


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 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.

Range: 2 through 1000
Default: 3 files

flag flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. You can include the following flags:

  • all—Trace all operations.
  • config—Trace configuration events.
  • general—Trace general flow.
  • packet—Trace ANCP packet transmit and receive operations.
  • process—Trace process internals.
  • protocol—Trace protocol events.
  • restart—Trace process restart flow
  • routing-socket—Trace routing socket events.
  • session—Trace connection events and flow.
  • startup—Trace ANCP startup events and flow.
  • subscriber—Trace subscriber events.
  • timer—Trace timer processing.

level—Level of tracing to perform. You can specify any of the following levels:

  • all—Match all levels.
  • error—Match error conditions.
  • info—Match informational messages.
  • notice—Match notice messages about conditions requiring special handling.
  • verbose—Match verbose messages.
  • warning—Match verbose messages.

disable—Disable this trace flag.

match regex—(Optional) Refine the output to include lines that contain the regular expression.

no-remote-trace—Disable remote tracing.

no-world-readable—(Optional) Disable unrestricted file access.

size size—(Optional) Maximum size of each trace file, in kilobytes (KB), megabytes (MB), or gigabytes (GB). If you specify a maximum file size, you also must 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 1 GB
Default: 128 KB

world-readable—(Optional) Enable unrestricted file access.

Required Privilege Level

trace—To view this statement in the configuration.

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