Release Information

Statement introduced in JUNOS Release 8.5.

Description

Configure tracing operations for extended DHCP relay agent processes.

Default

If you do not include this statement, no tracing operations are performed.

Options

file-name —Name of the file to receive the output of the tracing operation. Enclose the name in quotation marks (“ ”). All files are placed in a file named jdhcpd in the directory /var/log. If you include the file statement, you must specify a filename.

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 and a filename.

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 events
  • auth—Trace authentication events
  • database—Trace database events
  • fwd—Trace firewall process events
  • general—Trace miscellaneous events
  • ha—Trace high availability-related events
  • interface—Trace interface operations
  • io—Trace I/O operations
  • packet—Trace packet decoding operations
  • packet-option—Trace DHCP option decoding operations
  • rpd—Trace routing protocol process events
  • rtsock—Trace routing socket operations
  • session-db—Trace session database operations
  • state—Trace changes in state
  • ui—Trace user interface operations

match regex —(Optional) Refine the output to include lines that contain the regular expression.

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 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 also must specify a maximum number of trace files with the files option and filename.

Syntax: xk to specify KB, xm to specify MB, or xg to specify GB
Range: 0 bytes through 4,294,967,295 KB
Default: 128 KB

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

The remaining statements are explained separately.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
