traceoptions (LLDP)

 

Syntax

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 9.6.

Description

Set LLDP protocol-level tracing options.

Default

The default LLDP protocol-level 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 spanning-tree protocol tracing output in the file /var/log/stp-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: 1 trace file only

flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. The following are the LLDP-specific tracing options:

  • all—Trace all operations.

  • config—Log configuration events.

  • interface—Trace interface update events.

  • protocol—Trace protocol information.

  • rtsock—Trace socket events.

  • vlan—Trace vlan update events.

The following are the global tracing options:

  • all—All tracing operations.

  • config-internal—Trace configuration internals.

  • general—Trace general events.

  • normal—All normal events. This is the default. If you do not specify this option, only unusual or abnormal operations are traced.

  • parse—Trace configuration parsing.

  • policy—Trace policy operations and actions.

  • regex-parse—Trace regular-expression parsing.

  • route—Trace routing table changes.

  • state—Trace state transitions.

  • task—Trace protocol task processing.

  • timer—Trace protocol task timer processing.

no-world-readable—(Optional) Prevent any user from reading the log file. This is the default. If you do not include this option, tracing output is appended to an existing trace file.

size maximum-file-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: 1 MB

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.
