traceoptions (Protocols Secure Neighbor Discovery)

Syntax

Hierarchy Level

Description

Configure tracing operations for Secure Neighbor Discovery events. To specify more than one tracing operation, include multiple flag statements.

Options

file filename—Name of the file to receive 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 must also specify a maximum file size with the size option.

  • Range: 2 through 1000 files

  • Default: 10 files

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

Secure Neighbor Discovery Tracing Options

  • configuration—All configuration events.

  • cryptographic-address—Cryptographically generated address events.

  • protocol—All protocol processing events.

  • rsa—RSA events.

Global Tracing Options

  • all—All tracing operations.

You can specify one or more of following flag modifiers:

  • detail—Provide detailed trace information.

  • receive—Packets being received.

  • send—Packets being transmitted.

match regular-expression—(Optional) Specify a regular expression to match the output of the trace file you want to log.

no-remote-trace—Disable remote tracing globally or for a specific tracing operation.

no-world-readable—(Optional) Prevent any user from reading this 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.

  • 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 this log file.

Required Privilege Level

routing and trace—To view this statement in the configuration.

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

Release Information

Statement introduced in Junos OS Release 9.3.
