Release Information
Statement introduced in JUNOS Release 9.0.
Description
Define tracing operations for DHCP processes.
Options
-
file filename—Name of the file that receives the output of the tracing operation. Enclose the name in quotation marks. All files are placed in the directory /var/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 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 operations.
- auth—Trace authentication operations.
- 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 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: 10 KB through 1 GB
- Default: 128 KB
-
world-readable—(Optional) Enable unrestricted file access.
