traceoptions (PPPoE)

 

Syntax

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 9.6.

Option filter introduced in Junos OS Release 12.3

Description

Define tracing operations for PPPoE processes.

Options

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 to create before overwriting the oldest one. 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

disable—Disable this trace flag.

filter—Additional filter to refine the output to display particular subscribers. Filtering based on the following subscriber identifiers simplifies troubleshooting in a scaled environment.

Best Practice

Due to the complexity of agent circuit identifiers and agent remote identifiers, we recommend that you do not try an exact match when filtering on these options. For service names, searching on the exact name is appropriate, but you can also use a regular expression with that option.

  • aci regular-expression—Regular expression to match the agent circuit identifier provided by PPPoE client.

  • ari regular-expression—Regular expression to match the agent remote identifier provided by PPPoE client.

  • service regular-expression—Regular expression to match the name of PPPoE service.

  • underlying-interface interface-name—Name of a PPPoE underlying interface. You cannot use a regular expression for this filter option.

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.

  • events—Trace events.

  • gres—Trace GRES events.

  • init—Trace initialization events.

  • interface-db—Trace interface database operations.

  • memory—Trace memory processing events.

  • protocol—Trace protocol events.

  • rtsock—Trace routing socket events.

  • session-db—Trace connection events and flow.

  • signal—Trace signal operations.

  • state—Trace state handling events.

  • timer—Trace timer processing.

  • ui—Trace user interface 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 warning messages.

Default: error

match regular-expression—(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 maximum-file-size—(Optional) Maximum size of each trace file. By default, the number entered is treated as bytes. Alternatively, you can include a suffix to the number to indicate 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: sizek to specify KB, sizem to specify MB, or sizeg to specify GB

Range: 10240 through 1073741824

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.
