traceoptions (Protocols Link Management)

Syntax

Hierarchy Level

Release Information

Statement introduced before Junos OS Release 7.4.

Support for hello-packets, packets, and state flags added in Junos OS Release 8.1.

Description

Trace options for the LMP protocol.

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.

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 must also include the size statement to specify the maximum file size.

• all—Trace all available operations
• hello-packets—Trace hello packets on any LMP control channel
• init—Output from the initialization messages
• packets—Trace all packets other than hello packets on any LMP control channel
• parse—Operation of the parser
• process—Operation of the general configuration
• route-socket—Operation of route socket events
• routing—Operation of the routing protocols
• server—Server processing operations
• show—show command servicing operations
• state—Trace state transitions of the LMP control channels and traffic engineering links

• detail—Provide detailed trace information
• receive—Packets being received
• send—Packets being transmitted

no-world-readable—(Optional) Prevent all users from reading 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 this 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 include the files statement to specify the maximum number of files.

world-readable—(Optional) Enable log file access for all users.

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.
