traceoptions (Captive Portal Content Delivery)


Hierarchy Level


Define tracing operations for captive-portal-content-delivery processes.


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. Ensure that filenames are unique for each logical system or routing instance in which Mobile IP is configured.


Global messages (common to all logical systems and routing instances) are always saved in /var/log/mipd. Messages that are specific to a logical system or routing instance are never saved in /var/log/mipd. If you do not configure a trace filename for a logical system or routing instance, then nothing is traced for that entity.

size size—(Optional) Maximum size of each trace file, in 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: xk to specify KB, xm to specify MB, or xg to specify GB

  • Range: 10 KB through 1 GB

  • Default: 128 KB

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 also must specify a maximum file size with the size option.

  • Range: 2 through 1000

  • Default: 3 files

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.

  • clicommand—Trace CLI command operations.

  • configuration—Trace home agent state machine operations.

  • general—Trace general operations.

  • gres—Trace graceful routing switchover operations.

  • ipc—Trace Inter-Process Communication (IPC) messages between the PIC and the Routing Engine.

  • rtsock—Trace routing socket operations.

  • rules—Trace rules operations.

  • ssets—Trace service sets operations.

  • statistics—Trace statistics operations.
