traceoptions (Uplink Failure Detection)

Syntax

Hierarchy Level

Description

Define tracing operations for uplink failure detection.

Default

The traceoptions feature is disabled by default.

Options

file filename—Name of the file to receive the output of the tracing operation. Enclose the name within quotation marks.

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 (xk to specify KB, xm to specify MB, or xg to specify gigabytes), at which point 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 everything.

  • dcd—Trace ufdd interaction with dcd.

  • groups—Trace uplink-failure-detection group handling.

  • interface—Trace interface notifcation handlers of ufdd.

  • parse—Trace configuration parsing.

no-stamp—(Optional) Do not place a timestamp on any trace file.

no-world-readable—(Optional) Restricted file access to the user who created the 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 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 files option.

  • Syntax: xk to specify KB, xm to specify MB, or xg to specify gigabytes

  • Range: 10 KB through 1 GB

  • Default: 128 KB

world-readable—(Optional) Enable unrestricted file access.
