Release Information

Statement introduced before JUNOS Release 7.4.

Description

Trace traffic flowing through a VPLS routing instance.

Options

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.

file filename—Name of the file to receive the output of the tracing operation. Enclose the name in quotation marks (" ").

files number—(Optional) Maximum number of trace files. When a trace file named trace-file reaches this size, it is renamed trace-file.0. When 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 number of files, you also must specify a maximum file size with the size option.

Range: 2 through 1000 files
Default: 2 files

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

  • all—All VPLS tracing options
  • connections—VPLS connections (events and state changes)
  • error—Error conditions
  • nlri—VPLS advertisements received or sent by means of the BGP
  • route—Routing information
  • topology—VPLS topology changes caused by reconfiguration or advertisements received from other provider edge (PE) routers using BGP

flag-modifier—(Optional) Modifier for the tracing flag. You can specify the following modifiers:

  • detail—Provide detailed trace information.
  • disable—Disable the tracing flag.
  • receive—Trace received packets.
  • send—Trace sent packets.

no-world-readable—Do not allow 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 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.

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

world-readable—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.
